Bamboo Utilization in the Peleng Island, Banggai Kepulauan, Central Sulawesi, Indonesia

Bamboo is a useful plant that holds significant cultural and economic importance, particularly in small Indonesian islands like Peleng Island in Central Sulawesi. This paper explores bamboo utilization on Peleng Island, aiming to broaden our understanding of bamboo use on small Indonesian islands and shed light on local wisdom in bamboo utilization. The research was conducted on Peleng Island in 2019. Information on bamboo utilization was gathered through in-depth interviews with residents. Bamboo materials were collected and sent to the Herbarium Bogoriense for identification. The data were analysed descriptively. There are six bamboo species utilized on Peleng Island, namely Bambusa vulgaris, Dendrocalamus asper, Gigantochloa atter, Neololeba atra, Schizostachyum brachycladum, and Schizostachyum lima. Bamboo on Peleng Island is used for building materials (roofs, pillars, and wall weaving), cooking traditional foods like nasi jaha and bambu suman, and for various other uses (ornamental plants, water containers, stairs, poles for picking fruits/cloves, pest traps, and fish trap).

Beyond nutmeg, mace, and cloves: Checklist of the liverworts and hornworts of Maluku Islands (Moluccas), Indonesia.

The first ever liverwort and hornwort checklist is provided for the Maluku Islands (Moluccas/Spice Islands) of Indonesia. We report 355 accepted and 16 doubtful species and reject 22 species previously reported for Maluku Islands. The list is based on the specimens housed in the Herbarium Bogoriense (BO) and reports from over 500 literature references, including monographs, regional studies, and molecular investigations. The Maluku Islands are part of the Wallacea Biodiversity Hotspot with many unique species found only in Wallacea. Publications focusing on liverworts and hornworts of Maluku Islands are few and scattered. Considering regionally widespread species that have been recorded elsewhere, we predict that further fieldwork exploring the diversity of habitats coupled with collections unveiled from regional herbaria, a number of new records remain to be reported.

A checklist of Frullania (Frullaniaceae, Marchantiophyta) in Sulawesi based on herbarium specimens and literature

Frullania cordistipula is new to Sulawesi.

Preliminary study on variations in local varieties of bornean ironwood (Eusideroxylon zwageri Teijsm. & Binn.) based on vegetative characters

Bornean Ironwood (Eusideroxylon zwageri), a monotypic species of Eusideroxylon, is threatened due to its rarity in its natural habitat. It is a Class I timber commodity in Indonesia and known with several local varieties determined by local people. This study aimed to described the local varieties of ironwood from Kalimantan by taxonomic study. Field exploration had been carried out during 2022 to 2023 in North Kalimantan, East Kalimantan, and West Kalimantan provinces to collect herbarium specimens of ironwood local varieties. The specimens were then observed and characterized in Laboratory of Plant Biosystematics-BRIN. Observation was also done for ironwood collection available at Herbarium Bogoriense. Fourty one characters extracted from vegetative parts, such as stems, twigs and leaves were used to find clades within ironwood species. Phenetic analysis generated six clades in which hair characters on twigs and leaves and color variations of twigs and petiole were the main informative characters that differentiate between clades at an infraspecific level. Anatomical characters cannot be used as supporting characters in this study. Support from deeper morphological analysis involving more specimens and species groups affiliated with the genus Eusideroxylon, as well as molecular analysis is needed to strengthen the grouping at an infra-specific level.

Nothaphoebe Blume is a genus of the Lauraceae or Medang-medangan family, and is included in the Persea subgroup together with the genera Alseodaphne, Dehaasia, Persea, and Phoebe. Information on the diversity of Nothaphoebe in Sumatra, especially in Lampung province, has never been reported. Therefore, the aim of this study was to understand the morphological characters and species of Nothaphoebe occured in Lampung. The morphological characters observed included twigs, leaf shape, flowers, and fruits. The results of morphological characterisation show that there are five species of Nothaphoebe, i.e., Nothaphoebe falcata, Nothaphoebe foetida, Nothaphoebe macrocarpa, Nothaphoebe magnifica, and Nothaphoebe umbelliflora. Identification key for species, descriptions of each species and distribution maps are presented in this article. Keywords: Herbarium Bogoriense, Lauraceae, Morphology, Nothaphoebe, Lampung Province

Endemic Bamboo (Poaceae, Bambusoideae) of the Lesser Sunda Islands

More than 40 species of bamboo were known from the Lesser Sunda Islands (LSI), including several endemic species. Endemic species are often highly specialized, found in limited geographical areas, and vulnerable to extinction if their habitat is destroyed. This study aimed to provide an account of endemic bamboo species on the LSI. Fieldwork involved collecting samples of bamboo in the LSI. Herbarium specimens of bamboo deposited in the Herbarium Bogoriense (BO), collected from the LSI were examined, and endemic LSI species were recorded. The conservation status followed the International Union for Conservation of Nature (IUCN) red list categories and criteria. The conservation status of unassessed species was evaluated using IUCN red list categories and criteria. A spatial analysis was also conducted. Data were analyzed and presented descriptively. There are 10 endemic bamboo species in the LSI, namely Bambusa ooh Widjaja & Astuti from Bali (conservation status: endangered), Chloothamnus reholttumianus (Soenarko) Widjaja from Sumba (vulnerable), C. schmutzii (S.Dransf.) Widjaja from Sumbawa and Flores (near threatened), Dinochloa kostermansiana S.Dransf. from Sumba and Flores (near threatened), D. sepang Widjaja & Astuti from Bali (vulnerable), Fimbribambusa rifaiana Widjaja from Alor (near threatened), Gigantochloa aya Widjaja & Astuti from Bali (vulnerable), G. baliana Widjaja & Astuti from Bali (vulnerable), G. taluh Widjaja & Astuti from Bali (vulnerable), and Schizostachyum purpureum Damayanto & Widjaja from Sumba (data deficient). They can be found at an altitude of 20–1700 m in various habitats, including forests, bamboo forests, villages, botanical gardens, along a road, slopes, valleys, riverbanks, and around a lake.

Bamboo diversity in Weh Island, Aceh, Indonesia

Abstract. Ritonga MA, Syamsuardi, Nurainas, Damayanto IPGP. 2023. Bamboo diversity in Weh Island, Aceh, Indonesia. Biodiversitas 24: 2563-2576. Bamboo is an important plant resource in Indonesia, whose inventories were mostly conducted on the main islands. In contrast, the inventory for small islands, such as Weh Island in Northern Sumatra, has never been done. Weh Island, however, is an atoll island that has been raised above sea level and is suspected to have a unique diversity of flora, especially bamboo. This study aimed to understand the diversity of bamboo on Weh Island. Fieldwork was conducted in August-September 2022 in Weh Island, Aceh, Indonesia. Bamboo specimens were collected by collecting flora diversity method and deposited in Herbarium Andalas and Herbarium Bogoriense. Morphological characteristics were observed to identify and arrange species descriptions and as a determination key. The spatial distribution of bamboo was analyzed using QGIS software and overlaid with a land cover and altitude map. We also performed a similarities analysis using morphological characteristic. There are eight species of bamboo on Weh Island: Bambusa multiplex (Lour.) Raeusch. ex Schult.f., Bambusa spinosa Roxb., Bambusa tuldoides Munro,Bambusa vulgaris Schrad. ex J.C.Wendl., Dendrocalamus asper (Schult.f.) Backer, Schizostachyum brachycladum (Kurz ex Munro) Kurz, Schizostachyum silicatum Widjaja, and Thyrsostachys siamensis Gamble. B. vulgarisis most abundant and widespread on Weh Island; meanwhile, B. multiplexand B. tuldoidesare the least common. The presence of S. silicatum on Weh Island and Bangka Island was additional information on the expansion of these species distributions outside the mainland of Sumatra. Bamboos on Weh Island were found around settlements, plantations, and forests at 1 to 212 m asl. Bamboo species on Weh Island can be clustered into four groups based on their morphological characteristics.

Bamboo Diversity in the Maluku Islands, Indonesia

There is little documentation of bamboo species diversity and distribution in the Maluku Islands of Indonesia. This study aimed to provide information on the diversity and distribution of Maluku’s bamboo species. The research was conducted in March‒April 2021 at the Herbarium Bogoriense (BO), National Research and Innovation Agency. Herbarium specimens of bamboo in BO collected from the Maluku Islands (Provinces of Maluku and North Maluku) were studied alongside online scanned images of herbarium specimens. Bamboo species were re-identified and validated. A literature study was conducted to enrich the data. A distribution map of bamboo species in the Maluku Islands was compiled. Data were analyzed and presented descriptively. We built an identification key for the bamboo species in the Maluku Islands. There are 16 species and eight genera of bamboo in the Maluku Islands: Bambusa glaucophylla, B. maculata, B. multiplex, B. spinosa, B. tuldoides, B. vulgaris, Dendrocalamus asper, Gigantochloa atter, G. robusta, Neololeba amahussana, N. atra, Phyllostachys aurea, Racemobambos ceramica, Schizostachyum brachycladum, S. lima, and Thyrsostachys siamensis. These bamboo species were found across Maluku Province (Buru, Ambon, Seram, Kei Kecil, Kei Besar, Yamdena, and Tanimbar) and North Maluku Province (Ternate, Tidore, Halmahera, Obi, and Sula) at an altitude of 1‒1100 m above sea level in primary and secondary forests, limestone, peatland edges, city parks, and gardens.

Natural distribution of the genus Dacrydium Lamb. (Podocarpaceae) in Central Kalimantan, Indonesia

Abstract. Maimunah S, Kessler PJA, Indrioko S, Naiem M. 2022. Natural distribution of the genus Dacrydium Lamb. (Podocarpaceae) in Central Kalimantan, Indonesia. Biodiversitas 23: 2816-2822. The tropical coniferous genus Dacrydium is widespread in Kalimantan, Indonesia. It is estimated that four species still exist in Borneo, locally known as Alau. This genus thrives in a range of habitats, from heath to deep-peat forests in Central Kalimantan. This genus is currently threatened by logging, fire, and forest conversion to plantations. The objectives of this study were: 1) to know the distribution and abundance of Dacrydium, and 2) to describe the Dacrydium’s habitat. The research was conducted in a heath forest located in PT Taiyoung Engreen (PTTE) in Gunung Mas District and PT Dasa Intiga (PTDI) in Kapuas and North Barito District, and in deep-peat swamp forest located in Sebangau National Park (SNP) in Palangka Raya and Pulang Pisau District. Data were collected in plots, each measuring 50 x 80 m, and the collected data were analyzed using a biodiversity calculator device created by MSU in USAID Lestari 2019. The identified specimens of alau found were sent to Herbarium Bogoriense for validation. The results of the analysis showed that we could identify three species of alau from the four species that are suspected to exist in Kalimantan. namely Dacrydium beccarii Parl. (alau bakam (B)); Dacrydium pectinatum de Laub. (alau kelangkang (K)), and Dacrydium elatum (Roxb.) Wall. ex Hook. (alau tombak (T)) with various abundance. Depending on the conditions of habitat, Alau could be found only in some parts of heath to deep-peat swamp forest. The finding of D. pectinatum in the study areas is a new discovery because it was previously reported that this species was not found in Central Kalimantan.

Trachea features and fiber dimensions of fast-growing tree: A case study on wood samples from eastern Indonesia

Fast-growing plant is one of the characteristics of pioneer plants. Commonly, the plants grow in areas that is exposed to sunlight such as open area and forest edges. Fast-growing plants have different anatomical and physical wood characteristics compare with slow-growing plants. Therefore, this study aims to examine the anatomical characteristics of fast-growing plants, especially trees, namely the fiber cells and trachea features. A total of 33 wood samples from 28 species were used in this study. We used wood samples from Eastern Indonesia deposited at Herbarium Bogoriense. Examined wood samples are taken from branches with 1-2 cm of diameter. The anatomical characters observed were focused on two types of cells, namely fiber cells (fiber length, fiber diameter, fiber cell wall thickness, lumen width, identification of septate fibers and fibers pit) and the trachea (perforation type, pit arrangement, and pit form). From the observations of all wood samples showed that the length of fiber cells are classified as short (18 species) and medium (10 species) fiber. There are two groups of fiber cell wall thickness viz. very thin (16 species) and thin to thick (12 species). Septate fibers only found in 7 species especially Chisocheton and Teijsmanniodendron. Fiber’s pit observed in Horsfieldia parviflora, Mallotus peltatus, dan Neuburgia corynocarpa. All species have simple tracheal perforation with alternate or opposite pit arrangement. Moreover, branch wood samples have polygonal pit shape, oval or combination of those two shapes were found in some species, such as Horsfieldia parviflora, Sandoricum koetjape and Teijsmanniodendron bogoreinse.

Notes on leaf anatomy: Additional information for Indonesian Pandanus spp. (Pandanaceae)

In Indonesia, Pandanus spp. were distributed from Sumatra to Papua. These Pandanus species has broader variation of anatomical leaf characters whether epidermis or transversal section traits. This study was conducted to obtain an information of anatomical characters of Pandanus leaf and supporting character on Pandanus identification. Pandanus collections of Herbarium Bogoriense were used for this study, and some of Pandanus species from Papua New Guinea and Malay Peninsula were added as well. Paraffin method and simple peeling of the leaf surface were used to get leaf transversal sections and epidermis characters. In general, anatomical characters of examined species in this study relatively similar to other Pandanus species which were studied by former researchers. Pandanus has broad range of stomata types on the lower leaf surface, from simple stomata to the most specialized stomata. The upper leaf surface of Pandanus spp. has similar stomata type, viz. class 1 (simple). Zonation always presents on all species, except on P. atropurpureus, P. conoideus and P. nitidus. Mostly, crystals CaCO3 were found in three forms, namely rectangular and needle-like shape in idioblast cells, while prism-shape is scattered in the mesophyll area. These crystal shapes absent in P. odorifer and there is one additional crystal shape, drusse which present in P. conoideus. Silica bodies located in the upper and lower hypodermis of leaf. Bundle sheath extension was seen in all species except P. beguinii, P. conoideus, and P. fusinus.

Abstract. Mildawati, Sobir, Sulistijorini, Chikmawati T. 2021. Diversity, distribution and ecology of Davallia in Sumatra (Indonesia) and the nearby small islands. Biodiversitas 23: 33-42. Davallia is an epiphytic fern genus that shows high morphological variations in many characters. This genus is widely distributed in the tropics and subtropic areas. The diversity of Davallia has not been explored and recorded in many regions, including in Sumatra Island and its surrounding small islands. Therefore, this research aimed to study the diversity of Davallia species in Sumatra and the nearby small islands based on morphological variation, as well as to investigate their distribution and ecology. Samples were collected from Kerinci Seblat National Park (NP), Bukit Tiga Puluh NP, Siberut NP, Sipora Island, North Pagai Island and South Pagai, Bukit Barisan Grand Forest Park, and Bukit Barisan Selatan NP. In total, 369 specimen sheets (i.e.145 specimens from field explorations and 224 specimens from Herbarium Bogoriense collections) were examined its morphological characters. The results showed that as many as 13 species of Davallia were recorded in Sumatra and the nearby small islands. The species found are D. angustata Wall., D. corniculata T. Moore, D. denticulata (Burm. f.) Kuhn var. denticulata, D. divaricata Blume, D. heterophylla Sm., D. hymenophylloides (Bl.) Kuhn, D. parvula Wall., D. pectinata Sm., D. pentaphylla Blume, D. repens Kuhn, D. solida (G.Forst.) Sw. var. solida, D. trichomanoides Blume var. lorranii (Hance) Holttum, D. trichomanoides Blume var. trichomanoides, and D. triphylla Hook. Ten of which were new records for this location. There were 12 spesies found in Sumatra Island except D. parvula Wall. and 11 species found on the small islands around Sumatra except for D. corniculata T. Moore and D. divaricata Blume. Davallia denticulata (Burm. F.) Kuhn var. denticulata and D. solida (G.Forst.) Sw. var. solida had the largest number of specimens found. Almost all species had a random distribution pattern at altitudes of 1000-1500 m above sea level.

Dinochloa Scandens (Poaceae-Bambusoideae): Distribution, Habitat Preference, and Notes on Synonymy

The distribution of Dinochloa scandens is unclear. World bamboo checklists suggest it is relatively widespread in Malesia. Here we clarify issues with herbarium specimen identification. Besides, a synonym name of D. scandens, namely D. macrocarpa collected from the Philippines, needs to be reviewed. The study aims to provide information on distribution and to review the synonym of D. scandens. The habitat preferences of D. scandens are also presented. We carried out targeted fieldwork at Gunung Halimun-Salak National Park in West Java in 2019 and extensive examination of herbarium specimens from Herbarium Bogoriense and online portals to accurately circumscribe this species. All data were analyzed descriptively. Distribution, altitude, and rainfall maps for D. scandens were produced with ArcGIS Pro. Our examination on the specimens suggests that D. scandens is indeed endemic to West Java and Banten Provinces in Indonesia. This bamboo species can be found in lowland to mountain forests with an altitude of 20-1400 m, in areas with annual rainfall between 3000-4000 mm. We support D. macrocarpa as an accepted name for a bamboo species from the Philippines and remove it from synonymy with D. scandens due to clear differences in the fruit compared to specimens of D. scandens across its range.

THE GENUS PYCNOPORUS IN INDONESIA

The genus Pycnoporus is a member of Phylum Basidiomycota. This fungus is one of polypore genera that is easily recognized from the orange color of the fruiting body and it likely has high morphological features. Currently, there are 207 number fungal specimens kept in Herbarium Bogoriense (BO) under the genus Pycnoporus, and they were identified as P. sa-nguineus (L.) Murrill, P. cinnabarinus (Jacq.) P. Karst., and Pycnoporus sp. To ensure that those species name of the Pycnoporus collections is correct, thus this study was carried out. Re-identification process on the fungal collections was done based on macro-micromorphological features of all Pycnoporus specimens. This study revealed that species Pycnoporus collections stored in BO represent 2 species: P.sanguineus (L.) Murrill and P. puniceus (Fr.) Ryvarden. In addition, some specimens under the name P. cinnabarinus should be validated as P. puniceus. This information will be very useful for fungal taxonomists, non-taxonomists, and people who work on Pycnoporus species from Indonesia.

The diversity of bamboo species in the Indrokilo Botanical Garden is relatively low compared to some botanical gardens in Indonesia.</p>

Xylaria sp.; The Candle Snuff Fungus from West Java

Candle snuff fungus belongs to Xylaria group. Generally, Xylaria has a form like stick or candle or elongated fruit of shapes. Xylaria is classified into Ascomycota within Xylariaceae. This study found one species of candle-shaped mushroom in IPB Unversity. This study aimed to identified and characterized the specimen using molecular and morphological data. The specimen was collected and preservedinto FAA solution and deposited into Herbarium Bogoriense as BO 24426. Molecular analyses using Large Subunit as a region for amplification showed that the BO 24426 was classified into Xylaria sp. This species closes to Xylaria consociata. The stromata were erected, unbranched, and tapered to the apex. The texture was rigid and hard. Ascus bore 8 ascospores. The ascospores were fusiform or bean-shaped and smooth. The morphological observations supported molecular identification of BO 24426 as Xylaria sp. Other genes were needed to ensure the exact species of Xylaria

Short Communication: Note on the genus Dorstenia Plum. ex L. (Moraceae) in Java (Indonesia) and noteworthy information on the identity of D. bahiensis through ITS sequence

Abstract. Irsyam ASD, Hariri MR, Peniwidiyanti, Irwanto RR. 2021. Short Communication: Note on the genus Dorstenia Plum. ex L. (Moraceae) in Java (Indonesia) and noteworthy information on the identity of D. bahiensis through ITS sequence. Biodiversitas 22: 3358-3363. Dorstenia Plum. ex L. grouped within tribe Dorstenieae in the Moraceae. The genus comprises 105 species that are distributed in the African, Asian, and Neotropical regions. Previous studies showed that Java Island has only one species of Dorstenia, namely D. contrajerva L. This exotic species was introduced a long time ago and naturalized in Java. The field survey was carried out in Banten, Jakarta, West Java, and East Java. Herbarium study was also carried out in Herbarium Bogoriense and Herbarium Bandungense. There are two additional species from Java, D. bahiensis Klotzsch ex Fisch. and C.A. Mey. and D. foetida (Forssk.) Schweinf. Dorstenia bahiensis originated from Eastern Brazil and was found naturalized in Mekarwangi Village, Lembang, Bandung Barat regency, Indonesia. Dorstenia foetida is native to Africa and is only found as a popular cultivated plant. A molecular approach was carried out to provide the right identity of D. bahiensis because it has been mistakenly labeled as D. elata by a Javanese horticulturist. The internal transcribed spacer (ITS) sequence separated and distinguished both D. bahiensis and D. elata into different clades, which makes the popular name for D. elata actually D. bahiensis. Based on this study, there are three species of exotic Dorstenia in Java. The descriptions, photographs, and further discussions are provided.

Typification and taxonomic notes of Smilacaceae species in Java

Smilacaceae is known as a taxa with wide phenotypic variation and their taxonomical complexities remain unsolved. The three species of Smilacaceae housed in Java, are given nomenclature history. Since all the potential sources of original material have been investigated, but nothing has been identified, three neotypifications were designated here. Herbarium specimen of Koorders 34990β in Herbarium Bogoriense (BO) was chosen as the neotype of Smilax klotzschii. The de Groot & Wehlburg RD52 herbarium specimen in BO was chosen as the neotype of S. nageliana and Blume 463 herbarium specimen in L was chosen as the neotype of S. odoratissima.

A Phenetic Analysis of Korthalsia spp. in Sumatra Based on Morphological Characters

Korthalsia (Blume) is a genus in the sub-family Calamoideae of the family Arecaceae. Research on a phenetic study of Korthalsia in Sumatra has never been published. The research was conducted to describe the specific characteristics of Korthalsia spp. in Sumatra and analyze their morphological character and similarity with a phenetic analysis. There were 85 herbarium specimens of Korthalsia deposited at the Herbarium Bogoriense (BO). Twenty-four vegetative and six generative characters were observed. Scoring was analyzed with a multinomial approach. The analysis was performed using the NTSys pc 2.02. The result showed that nine species of Korthalsia in Sumatra were distinguished based on their ocrea types, leaflets shape, and rachillae. The phenogram showed a similarity coefficient value of 0.53 for two main clusters, cluster A consisting of 4 species of Korthalsia (K. debilis, K. paucijuga, K. rigida, and K. rostrata) and Cluster B consisting of 5 species (K. echinometra, K. flagellaris, K. laciniosa, K. hispida, and K. robusta).

Morphological characteristic and Phenetic Relationship of Lysurus periphragmoides Collected from West Java

Lysurus is one of the unique genera in Basidiomycetes. It has a stinky odor and slime on the head. The unusual-shaped makes the species in Lysurus easily to be identified. One of Lysurus had been found in West Java, Indonesia namely L. periphragmoides. The specimen was deposited into Herbarium Bogoriense with code BO 24418. This study aimed to obtain specimens and characterize the Lysurus BO 24418 using morphological characteristics, and analyze the phenetic relationship among Lysurus species. Lysurus BO 24418 has two phases (egg and mushroom). The egg phase is usually hypogeous underground. The mushroom has a head and stem. The head bears the mature spore with slime distribute malodor. The stem has a hollow and spongy texture with a yellowish color. The numerical data of morphological characters of species in Lysurus were analyzed using NTSys ver 2.1 software. Ten characters were used to build a dendrogram using Sequential Agglomerative Hierarchical Nested (SAHN) cluster analysis with Unweighted Pair Group Method with Arithmetic Mean (UPGMA). Phallus indusiatus was selected as an outgroup. The analyses showed the specimen was classified as L. periphragmoides with 100% of similarity coefficient and it was close L. gardneri with 40,4% of similarity coefficient. The characters that cluster among them are stem surface, head type, egg diameter, and spore max length
