New Series in Pedicularis (Scrophulariaceae)

Abstract

Three new series of Pedicularis, ser. Maximoviczianae, ser. Albertianae, and ser. Semenowianae, are described, and three species, P. maximoviczii, P chorgossica, and P albertii, are reported from China. Some of the Central Asian species of Pedicularis were not included in Flora Reipublicae Popularis Sinicae (Tsoong, 1963) but were reported later from Dzhungaria by Ivanina (1970). These include P. albertii Regel, P. maximoviczii Krassnow, and P. chorgossica Regel & Winkler. Pedicularis albertii and P. maximoviczii each belongs to a monotypic series, and the latter species most probably belongs to section Capitatae (Prain) Ivanina (Ivanina, 1991), rather than to section Cyclophyllum Bunge ser. Semenowianae Vvedensky (Vvedensky, 1955). Descriptions and distributions in China of these three species are herein provided. Tsoong (1963) placed Pedicularis semenowii Regel in series Caucasicae Maximowicz, but we believe that series Caucasicae is not represented in China. Pedicularis semenowii and three other Middle Asian species (P popovii Vvedensky, P karatavica Pavlov, and P waldheimii Bonati) belong to series Semenowianae. On the other hand, P chorgossica belongs to series Platyrrynchae Maximowicz rather than series Interruptae Vvedensky, as was determined by Vvedensky (1955). Pedicularis ser. Maximoviczianae Ivanina & T. N. Popova, ser. nov. TYPE: Pedicularis maximoviczii Krassnow. Radice crassa fasciculata; caule supra collum squamatum ramosissimo ramis dense caespitosis brevissimis glabris oligophyllus; foliis plerisque basalibus longe petiolatis, lamina pinnatisecta, segmentis oblongis; floribus roseo-albis amplis ramos omnes terminantibus breve capitatis; calyce hirsuto campanulato; corollae tubo erecto, galea falcata, ad angulum inferiorem breve truncata et infra apicem breve bidenticulata, labio galeam aequante. Capsula oblique ovato-oblonga cuspidata. Roots fleshy, fascicled, fusiform, thickened. Stems small, branched basally, branches long, alternate and opposite, crowded. Flowers axillary and apical, 1-3 on long pedicels. Corolla 3-3.5 cm; tube suberect; upper lip erect or slightly bent with small widely triangular teeth, beakless. Capsule obliquely ovate-oblong. Series Maximoviczianae is monotypic and is related to series Flexuosae Prain and series Acaules Prain. From series Flexuosae, it differs in having short stems (5-15 cm tall) and beakless corolla galeas, instead of stems more than 40 cm tall and corolla galeas with robust beaks. From series Acaules, it differs in having corolla galeas with 2 marginal teeth and flowers axillary and in apical inflorescences. In contrast, series Acaules has corolla galeas without marginal teeth and flowers exclusively axillary. Vvedensky (1955) placed Pedicularis maximoviczii in series Seminovianae Vvedensky, but species of this series typically have opposite or verticillate lower stem leaves and subcapitate inflorescences, instead of alternate lower stem leaves and non-capitate inflorescences characteristic of P. maximoviczii. In our opinion, series Maximoviczianae and Seminowianae are unrelated. Pedicularis maximoviczii Krassnow, Zap. Russk. Geogr. Obz. 19: 339. 1888; Scripta Bot. Horti Univ. Imp. Petrop. 2: 18. 1889. TYPE: China. Xinjiang: [Dzhungaria], Muzart, 1886, Krassnow s.n. (lectotype, here designated, LE). Herbs perennial. Roots fleshy, fusiform-thickened. Stems 5-15 cm tall, branched basally, glabrous. Basal leaves long-petiolate, 1-5 cm, lanuginose; stem leaves alternate, uppermost subopposite, crowded near inflorescences; blade 2-5 cm, lanceolate, pinnatisect, segments oblong, pinnatipartite. Flowers axillary, 1-3 with short pedicels on branches and 2 or 3 with long pedicels on apical inflorescences; bracts leaflike, petioles mostly pubescent. Calyx campanulate, membranous, densely pubescent, 1.2-1.5 cm; lobes narrowly triangular, serrate; tube 1.5X longer than lobes. Corolla reddish white, glabrous, 3-3.5 cm; tube straight, as long as upper lip; upper lip falcate, with 2 triangular teeth; lower lip as long as upper. Filaments 2 glabrous and 2 villous. Ovary conical. Capsule obliquely ovate-oblong. Flowering March-May, fruiting June-July. NovoN 7: 373-375. 1997.
