A new species of Aspalathus (Fabaceae, Crotalarieae) from the Cape Floristic Region, South Africa

A new species from the Western Cape, South Africa is described: Aspalathus praetermissa—a highly localized and critically endangered endemic, occurring between Elandsbaai, Redelinghuys, and Paleisheuwel. This species is morphologically similar to A. quinquefolia subsp. virgata, but differs in having small, 5.5–6.0 mm long, pale yellow flowers (versus flowers 7–10 mm long, bright yellow); more extensive pubescence on wing petals as well as keel petals, blade not flaring apically (versus wing petals partially pubescent to glabrous, flaring apically). A composite plate and map for A. praetermissa are presented, and a taxonomic key to the A. quinquefolia complex.

Floral pigments and their perception by avian pollinators in three Chilean Puya species.

The Chilean Puya species, Puya coerulea var. violacea and P. chilensis bear blue and pale-yellow flowers, respectively, while P. alpestris considered to be their hybrid-derived species has unique turquoise flowers. In this study, the chemical basis underlying the different coloration of the three Puya species was explored. We first isolated and identified three anthocyanins: delphinidin 3,3',5'-tri-O-glucoside, delphinidin 3,3'-di-O-glucoside and delphinidin 3-O-glucoside; seven flavonols: quercetin 3-O-rutinoside-3'-O-glucoside, quercetin 3,3'-di-O-glucoside, quercetin 3-O-rutinoside, isorhamnetin 3-O-rutinoside, myricetin 3,3',5'-tri-O-glucoside, myricetin 3,3'-di-O-glucoside and laricitrin 3,5'-di-O-glucoside; and six flavones: luteolin 4'-O-glucoside, apigenin 4'-O-glucoside, tricetin 4'-O-glucoside, tricetin 3',5'-di-O-glucoside, tricetin 3'-O-glucoside and selagin 5'-O-glucoside, which is a previously undescribed flavone, from their petals. We also compared compositions of floral flavonoid and their aglycone among these species, which suggested that the turquoise species P. alpestris has an essentially intermediate composition between the blue and pale-yellow species. The vacuolar pH was relatively higher in the turquoise (pH 6.2) and pale-yellow (pH 6.2) flower species, while that of blue flower species was usual (pH 5.2). The flower color was reconstructed in vitro using isolated anthocyanin, flavonol and flavone at neutral and acidic pH, and its color was analyzed by reflectance spectra and the visual modeling of their avian pollinators. The modeling demonstrated that the higher pH of the turquoise and pale-yellow species enhances the chromatic contrast and spectral purity. The precise regulation of flower color by flavonoid composition and vacuolar pH may be adapted to the visual perception of their avian pollinator vision.

The mechanism of white flower formation in Brassica rapa is distinct from that in other Brassica species.

A single nucleotide (G) deletion in the third exon of BraA02.PES2-2 (Bra032957) leads to the conversion of flower color from yellow to white in B. rapa, and knockout mutants of its orthologous genes in B. napus showed white or pale yellow flowers. Brassica rapa (2n = 20, AA) is grown worldwide as an important crop for edible oil and vegetables. The bright yellow flower color and long-lasting flowering period give it aesthetic qualities appealing to countryside tourists. However, the mechanism controlling the accumulation of yellow pigments in B. rapa has not yet been completely revealed. In this study, we characterized the mechanism of white flower formation using a white-flowered natural B. rapa mutant W01. Compared to the petals of yellow-flowered P3246, the petals of W01 have significantly reduced content of yellowish carotenoids. Furthermore, the chromoplasts in white petals of W01 are abnormal with irregularly structured plastoglobules. Genetic analysis indicated that the white flower was controlled by a single recessive gene. By combining BSA-seq with fine mapping, we identified the target gene BraA02.PES2-2 (Bra032957) homologous to AtPES2, which has a single nucleotide (G) deletion in the third exon. Seven homologous PES2 genes including BnaA02.PES2-2 (BnaA02g28340D) and BnaC02.PES2-2 (BnaC02g36410D) were identified in B. napus (2n = 38, AACC), an allotetraploid derived from B. rapa and B. oleracea (2n = 18, CC). Knockout mutants of either one or two of BnaA02.PES2-2 and BnaC02.PES2-2 in the yellow-flowered B. napus cv. Westar by the CRISPR/Cas9 system showed pale-yellow or white flowers. The knock-out mutants of BnaA02.PES2-2 and BnaC02.PES2-2 had fewer esterified carotenoids. These results demonstrated that BraA02.PES2-2 in B. rapa, and BnaA02.PES2-2 and BnaC02.PES2-2 in B. napus play important roles in carotenoids esterification in chromoplasts that contributes to the accumulation of carotenoids in flower petals.

Morphological and phenological characterization of Hedychium borneense R.M.SM of Borneo and its conservation management

Morphological, phenological characterization and conservation management of Hedychium borneense R.M.Sm, a terrestrial-epiphytic herb and endemic to Kalimantan, Borneo are described. Results revealed that H. bornensee has a purple-brownish bractea, a terminal and raceme inflorescence, pale yellow flowers with a broad and pale-yellow labellum and orange stamen, a triocular fruit with an orange to red inner color, and brownish seeds with a dark red arillus. There are six phenology phases: initiation phase, flower development phase, pre-anthesis phase, anthesis phase, post-anthesis phase, and fruit development. Flower development lasts for 34 days, with a two-day anthesis phase in between. The ripe fruit occurs on day 94. It grows best in porous, moist environment; sphagnum moss and sand mix compost (1:1) is the best media for this plant. Since the plant is endemic, ex-situ conservation management through generative propagation is observed to be essential. Bangladesh J. Bot. 51(2): 313-323, 2022 (June)

Systematic reinstatement of the Sumatra endemic species Mangiferasumatrana Miq. (Anacardiaceae).

Mangiferasumatrana Miq. is an endemic species from Sumatra. The taxonomic status of M.sumatrana remains unclear and is currently treated as a synonym of M.laurina. The present study employed morphological and palynological characters and molecular analyses to address the delimitation between the two species. Pollen observations were carried out with a Scanning Electron Microscope (SEM). Phylogenetic relationships were investigated using the ITS and the trnl-F intergenic spacer markers. M.sumatrana differs from M.laurina by having pyramidal panicles with a low density of pale yellow flowers pale, sepals 3-3.5 × 1.7-2 mm, fruit roundish to flattened with pale yellow pulp, a rough fibre texture, and pollen with a prolate spheroidal shape. The MP phylogenetic tree showed a divergent boundary between the two species suggesting that M.sumatrana could be an independent species, not a variety of M.laurina. The present study supports the view that these two taxa can be treated as different species.

Andaliman (Zanthoxylum Acanthopodium DC.), a Rare Endemic Plant from North Sumatra that Rich in Essential Oils and Potentially as Antioxidant and Antibacterial

Andaliman (Zanthoxylum acanthopodium DC.) is one of the endemic plants originating from North Sumatra. This plant is known for its benefits as a special seasoning spice in Batak tribe community. Humans as the image of God are given the ability to conduct an investigation and development of what God has created so that science begins to develop to investigate the potential of andaliman plants in the field of health. This writing aims to determine: 1) morphological and physiological characteristics of andaliman, 2) habitat of andaliman, and 3) utilization of andaliman as antioxidant and antibacterial agent. The method of writing used in the preparation of this article is the study of literature. The results of the literature study show that the andaliman plant has a tap root, woody stems, green, odd-numbered and jagged-edged compound leaves, pale yellow flowers, pepper-shaped fruits, and shiny black or wrinkled black seeds with thick and hard seed shells. Andaliman habitat is a place with an altitude of 1200-1500 masl with an average temperature of 15-18 ̊C and rainfall of 800-1000 mm/year and soil pH 5.5-7.6. Andaliman fruit contains 29 components of essential oils such as geranyl, cytronella, β-cytronelol, and nerol which have antioxidant activity. Andaliman fruit extract also has antibacterial activity, which inhibits the growth of microbes such as Escherichia coli, Salmonella typhimurium, Bacillus cereus, Pseudomonas fluorescens, Aspergillus flavus, Propionibacterium acnes and Staphylococcus aureus.

A new Pseudolepanthes (Pleurothallidinae: Orchidaceae) from Northwest Ecuador

A new species of the genus Pseudolepanthes discovered in Carchi province, northwest Ecuador, is described here. The new species is compared with P. zunagensis from which it is distinguished by a longer inflorescence with successive vinaceous or pale-yellow flowers, an elongate arcuate column, and a lip with an erect, thick, widely rectangular central callus.
 Keywords: Dracula Reserve, EcoMinga, Trichosalpinx, Trichosalpinx pseudolepanthes

Esterified carotenoids are synthesized in petals of carnation (Dianthus caryophyllus) and accumulate in differentiated chromoplasts

Although yellow and orange petal colors are derived from carotenoids in many plant species, this has not yet been demonstrated for the order Caryophyllales, which includes carnations. Here, we identified a carnation cultivar with pale yellow flowers that accumulated carotenoids in petals. Additionally, some xanthophyll compounds were esterified, as is the case for yellow flowers in other plant species. Ultrastructural analysis showed that chromoplasts with numerous plastoglobules, in which flower-specific carotenoids accumulate, were present in the pale yellow petals. RNA-seq and RT-qPCR analyses indicated that the expression levels of genes for carotenoid biosynthesis and esterification in pale yellow and pink petals (that accumulate small amounts of carotenoids) were similar or lower than in green petals (that accumulate substantial amounts of carotenoids) and white petals (that accumulate extremely low levels of carotenoids). Pale yellow and pink petals had a considerably lower level of expression of genes for carotenoid degradation than white petals, suggesting that reduced degradation activity caused accumulation of carotenoids. Our results indicate that some carnation cultivars can synthesize and accumulate esterified carotenoids. By manipulating the rate of biosynthesis and esterification of carotenoids in these cultivars, it should be feasible to produce novel carnation cultivars with vivid yellow flowers.

Taxonomic studies on Zingiberaceae of Myanmar II: Curcuma stolonifera (Subgenus Ecomatae), a new species from the northwestern region

In the course of taxonomic studies on Zingiberaceae in Myanmar, a new species of Curcuma assignable to subgenus Ecomatae was discovered in Htamanthi Wildlife Sanctuary, Sagaing Region, northwestern Myanmar. It is described and illustrated here as Curcuma stolonifera. This new species differs from other species in subgenus Ecomatae Skornick. & Sida f. in having a combination of the following characters; long creeping rhizomes, an oblong-lanceolate lamina with reddish midrib, a small number of green bracts, a central inflorescence, pale whitish yellow flowers, and a short slightly L-shaped anther with a curved spur.

In vitro propagation of Camellia fascicularis: a plant species with extremely small populations

Camellia fascicularis is an endangered evergreen ornamental plant with pale yellow flowers. An efficient and reproducible in vitro regeneration method is required for its large-scale propagation and germplasm conservation. In this study, one axillary bud per nodal stem was obtained from C. fascicularis cultured on Murashige & Skoog (MS) medium containing 0.1 mg L−1 indole-3-acetic acid (IAA) combined with 1.0 mg L−1 6-benzylaminopurine (BA). Axillary buds from the stem segments were transferred to modified woody plant medium (WPM) supplemented with 3.0 mg L−1 BA in combination with 0.3 mg L−1 IAA for multiplication, thereby resulting in a high shoot multiplication rate of 6.8. Multiple shoots were divided into nodal stems and shoot tips and were induced to root. The shoot tips were induced to root by culturing on one-half MS medium supplemented with 2.0 mg L−1 indole-3-butyric acid (IBA) in combination with 0.3 mg L−1 α-naphthalene acetic acid (NAA), which resulted in 76.0% rooting efficiency with 2.3 roots per shoot. The optimal hormone ratio for inducing rooting of nodal stems was 1.0 mg L−1 IBA in combination with 2.0 mg L−1 NAA, which resulted in 72.7% rooting efficiency with 1.7 roots per nodal stem. These two rooted plantlets were successfully acclimatized and established in a greenhouse.

Expression of CCD4 gene involved in carotenoid degradation in yellow-flowered Petunia × hybrida

Petunia is a popular commercial bedding plant that comes in many colors, but there are no petunia cultivars with deep yellow petals. The carotenoid degradation gene carotenoid cleavage dioxygenase (CCD4) was isolated from white and yellow-flowered petunia and we found the 226-bp insertion of a non-autonomous transposable element tourist-like miniature-inverted repeat (MITE) in the coding region of CCD4 only in yellow cultivars. The insertion interrupts gene expression because of a premature stop codon after the TE insertion and could form secondary structures in hairpin RNA that could then be processed into a mature miRNA. Here, the normal function of CCD4 isolated from a white cultivar was introduced to a yellow cultivar. The transformants showed more fading pale-yellow flowers and carotenoid content was decreased. These results indicate that transformed CCD4 expression promoted carotenoid degradation and the lack of CCD4 expression results in more carotenoid accumulation in wild-type yellow-flowered petunia.

Generation of Yellow Flowers of the Japanese Morning Glory by Engineering Its Flavonoid Biosynthetic Pathway toward Aurones.

Wild-type plants of the Japanese morning glory (Ipomoea nil) produce blue flowers that accumulate anthocyanin pigments, whereas its mutant cultivars show wide range flower color such as red, magenta and white. However, I. nil lacks yellow color varieties even though yellow flowers were curiously described in words and woodblocks printed in the 19th century. Such yellow flowers have been regarded as 'phantom morning glories', and their production has not been achieved despite efforts by breeders of I. nil. The chalcone isomerase (CHI) mutants (including line 54Y) bloom very pale yellow or cream-colored flowers conferred by the accumulation of 2', 4', 6', 4-tetrahydoroxychalcone (THC) 2'-O-glucoside. To produce yellow phantom morning glories, we introduced two snapdragon (Antirrhinum majus) genes to the 54Y line by encoding aureusidin synthase (AmAS1) and chalcone 4'-O-glucosyltransferase (Am4'CGT), which are necessary for the accumulation of aureusidin 6-O-glucoside and yellow coloration in A. majus. The transgenic plants expressing both genes exhibit yellow flowers, a character sought for many years. The flower petals of the transgenic plants contained aureusidin 6-O-glucoside, as well as a reduced amount of THC 2'-O-glucoside. In addition, we identified a novel aurone compound, aureusidin 6-O-(6″-O-malonyl)-glucoside, in the yellow petals. A combination of the coexpression of AmAS1 and Am4'CGT and suppression of CHI is an effective strategy for generating yellow varieties in horticultural plants.

Nomenclatural notes on Iris haussknechtii (Iridaceae)

The nomenclatural notes, discussed in the present communication, are based on the revision of Iris Linnaeus (1753: 38) names described from Turkey, considering this genus in its wide sense (e.g., Dykes 1924, Mathew 1989, Güner 2012). Iris haussknechtii Bornm. ex Baker (1892: 4) is a species endemic to Turkey referred to I. ser. Spuriae (Diels 1930: 502) Lawrence (1953: 361) of I. sect. Limniris Tausch (1823: without pagination), treated at the generic level under the name Chamaeiris Medikus (1790: 417) (Crespo 2011, Crespo et al. 2015). It is a rhizomatous, perennial herbaceous, compact plant, with two terminal pale yellow or yellow and white flowers on single stem, the perianth segments with only yellow veins, and the narrow, rather tough leaves slightly shorter than flowers. According to some authors (Dykes 1912, 1924, Peckham 1939, Mathew 1984), it is a close relative to I. sintenisii Janka (1877: 244), except for the colour of the flowers, the shape of the outer perianth segments, the fact that the spathe valves are not sharply keeled (Dykes 1924), and the reported chromosome number: 2n = 18 in I. haussknechtii (Özkan et al. 2001, as “I. kerneriana”) vs 2n = 16 in I. sintenisii (Popova & Ceschmedjiev 1975). Based on herbarium specimens examination (deposited at E, K, and P; acronym according to Thiers 2019), we conclude that I. haussknechtii is distributed in the following northern Turkey provinces: Canakkale, Balikesir, Bolu, Kastamonu, Cankiri, Ankara, Corum, Sinop, Amasya, Tokat, Erzincan, as well as in Eskisehir, Afyonkarahisar, Kirikkale, Kirsehir, and Sivas (A. Güner, pers. comm.). This plant usually occurs in open sites, on stony soil amongst woodland, in dry meadows, scrubland, and on steep stony slopes at elevations ranging from 1150 to 2350 m (Mathew 1984). At the best of our knowledge, the name I. haussknechtii has not yet been typified. After the examination of all the original material and protologue, we designated the lectotype for this name.

Leipoldtia nevillei(Aizoaceae: Ruschieae), a New Species from Coastal Namaqualand, South Africa

We describe a new species, Leipoldtia nevillei Klak, known from several populations between Soebatsfontein and Wallekraal in the coastal plain of Namaqualand, South Africa. The new species is easily recognized as a member of the Leipoldtia-clade by its smooth, xeromorphic leaves, mostly 10-locular fruits with large closing bodies and broad valve wings. In habit and floral morphology it resembles most closely the monotypic Hallianthus H.E.K.Hartmann, but it lacks the high turret-shaped fruits and the prominent subcentral elevations on the covering membranes that are characteristic for Hallianthus. In addition, L. nevillei differs from other species of Leipoldtia L.Bolus and from Hallianthus by its pale yellow or white flowers with a pale yellow centre. In the closely related Cephalophyllum the fruits form closing bulges below the covering membranes, whereas L. nevillei has closing rodlets below the covering membranes, as is typical for Leipoldtia.

Flower color and pigments in yellow-flowered hybrid progeny raised from the interspecific cross Pelargonium quinquelobatum × white-flowered geraniums

The aim of this study was to produce a yellow-flowered geranium (Pelargonium×hortorum Bailey). Interspecific crosses between white-flowered geraniums and Pelargonium quinquelobatum Hochst. ex A. Rich. were performed. Unilateral incompatibility was observed, such that normal seeds were obtained when P. quinquelobatum was used as the seed parent, whereas no seeds were obtained when P. quinquelobatum was used as the pollen parent. The F1 progeny produced sterile pollen; therefore, genome doubling of the F2 progeny was induced by colchicine treatment to ensure fertile pollen; F3 progeny were also produced. The F3 progeny were crossed with tetraploid geraniums to produce BC1 and BC1F2 progeny. The flower color of the hybrid progeny were pale yellow, ranged from green–yellow 1D to yellow 3C, according to the Royal Horticultural Society Color Chart, and became increasingly the value of the colorimetric parameter b* with advancing generations. The pigmentation of the pale yellow flowers involved a large amount of flavonols and a small amount of carotenoids: the main pigments were kaempferol or quercetin. The quercetin contents were significantly correlated with the b* value (r=0.82, P<0.001), whereas no correlation was found between the kaempferol or carotenoids contents and the b* value. Furthermore, the b* value was unaffected by the aluminum content or the pH value in the petals.

Review of the southern African Moraea ciliata complex (Iridaceae: Iridoideae) including the three new taxa M. flava and M. ciliata subsp. cuprina and subsp. lutescens

The Moraea ciliata complex (Moraea subg. Acaules) from the southern African winter-rainfall zone currently includes four vegetatively similar species: a widespread M. ciliata plus three more localized species, Moraea longipes, Moraea macronyx and Moraea tricolor. Examination of herbarium collections and wild populations of M. ciliata throughout its range indicates that the recognition of one new species and two subspecies better reflects the ecological and morphological patterns in the species. The new species Moraea flava from the western Karoo with pale yellow flowers and smooth leaves with thickened and crisped margins is sometimes sympatric with typical blue–flowered M. ciliata but blooms earlier in the season. M. ciliata subsp. cuprina is recognized for a series of pink- to red-flowered populations from deep sands along the Atlantic coast of Western Cape often with two inflorescences per plant and unusually long capsules. M. ciliata subsp. lutescens from stony sandstone-derived soils, mostly of montane habitats in Western Cape between Worcester and the Gifberg, differs consistently from blue- or white-flowered subsp. ciliata in its slightly smaller yellow flowers, narrower, usually hairless leaves, and short stamens with the filaments united for up to half their length. Unusual populations of small, white-flowered plants flowering in May and June from west and south of Swellendam are provisionally included in subsp. ciliata. These taxonomic changes render subsp. ciliata morphologically more homogeneous but still with a wide geographic range extending from the Cape Peninsula north to Springbok in Northern Cape and east though the western Karoo and Upper Karoo to near Lady Grey in Eastern Cape.

Thottea adichilthottiana(Aristolochiaceae), a new species from Ernakulam, Western Ghats, India

A new species of Thottea Rottb. (Aristolochiaceae) from Ernakulam District, Kerala, India, Thottea adichilthottiana Sunil and Naveen Kumar, is described and illustrated. The species is most similar to Thottea siliquosa (Lam.) Ding Hou, but differs from it in having a smaller habit with obovate or broadly elliptic–oblong leaves, depressed globose flower buds, pale yellow flowers, perianth lobes with long multicellular deep reddish purple hairs inside, 7–11 stigmatic lobes and in its green and glabrous fruits.

Desarrollo poscosecha de lirios (Lilium sp.) producidos en Duitama- Boyacá y la determinación del punto de corte

Colombia presenta una gran oferta exportadora de flores de corte, entre las que se encuentra el Lilium conocido como Lirio asiático. Esta especie se empezó a producir en el departamento de Boyacá en el año 2000, obteniéndose flores de excelente calidad, tamaño, resistencia y buena duración en florero. Sin embargo, se han observado problemas de rápida apertura, y baja vida útil en florero, especialmente cuando la flor se lleva a zonas cálidas. De aquí surgió la necesidad de identificar el punto de corte que garantice una mayor duración de la flor, y definir los métodos de selección y criterios de clasificación para que sean utilizados por los productores, el ensayo se realizó con flores variedad Nello (rojo) y girondo (amarillo pálido), provenientes de la finca “La Argentina” de Duitama, Boyacá. Las pruebas se llevaron a cabo en el laboratorio poscosecha de la Universidad Pedagógica y Tecnológica de Colombia, tomando 5 estados de apertura por variedad, con 3 tallos y con 5 repeticiones. Se estableció como punto óptimo de corte el 3, caracterizado por tener un botón entre 80 a 90 mm de largo y alcanzar una vida útil en florero de 15 días.

Eight new species of &lt;i&gt;Moraea&lt;/i&gt; (Iridaceae) from southern Africa with range extensions and morphological notes in the genus

We describe eight new southern African species in the largely sub-Saharan African genus Moraea L., one from the winterdry Great Karoo and the others from the winter-rainfall zone of the southwest of the subcontinent. M. striata Goldblatt J.C.Manning (subg. Visciramosae Goldblatt) from the southern foothills of the Great Swartberg Mtns has khaki-green flowers with reflexed tepal limbs streaked with dark lines. The acaulescent M. singularis Goldblatt J.C.Manning (subg. Umbellatae Goldblatt J.C.Manning) with terete leaf blades is restricted to the dry, interior foothills of the Kamiesberg in Northern Cape. M. filamentosa Goldblatt J.C.Manning, subg. Acaules (Baker) Goldblatt J.C.Manning, is described from the dry interior of Namaqualand in Northern Cape. The species is closely allied to the widespread M. falcifolia Klatt. In subg. Polyanthes (Goldblatt) Goldblatt J.C.Manning, we describe M. thermarum Goldblatt J.C.Manning (sect. Hexaglottis (Vent.) Goldblatt) from southwestern Namibia, allied to M. brevituba (Goldblatt) Goldblatt, and M. lazulina Goldblatt J.C.Manning (sect. Pseudospicata Goldblatt J.C.Manning) from the Little Karoo, until now confused with M. exiliflora Goldblatt but differing in its larger flowers with strongly reflexed tepals. The new M. petricola Goldblatt J.C.Manning (subg. Vieusseuxia (D.Delaroche) Goldblatt), is restricted to higher elevations of the Pakhuis Mtns of northern Western Cape. Lastly, in subg. Homeria (Vent.) Goldblatt J.C.Manning, we recognize M. doleritica Goldblatt J.C.Manning with pale yellow flowers and anthers exceeding the style branches, restricted to dolerite outcrops in the Great Karoo, and M. eburnea Goldblatt J.C.Manning from the northern foothills of the Klein Swartberg, which has a single, basal leaf and pale yellow flowers with filaments free distally. Moraea now has 222 species, including 203 in southern Africa, of which 200 are endemic to the region. In addition to describing new species, the paper brings to light range extensions of a further eight species: M. barnardii L.Bolus, M. elliotii Baker, M. exiliflora Goldblatt, M. falcifolia Goldblatt J.C.Manning, M. fenestralis (Goldblatt E.G.H.Oliver) Goldblatt, M. louisabolusiae Goldblatt, M. tulbaghensis L.Bolus and M. unguiculata Ker Gawl. Each of the species falls into one of the subgenera mentioned for the new species except M. fenestralis which belongs in subg. Galaxia.

К систематике Corydalis gorodkovii Karav. (Fumariaceae)

A new variety Corydalis gorodkovii Karav. var. coerulea Mikhailova var. nova is described from Suntar-Khayata Range. The new variety differs from the typical one by blue (not pale yellow) flowers.
