A new species of Gesneriaceae, Primulina melanofilamenta Ying Liu & F. Wen from Guangxi, China, is illustrated and described. It is morphologically distinct from the most similar species P. eburnea and P. atroglandulosa by the color of the corolla, dark purplish black filaments, anthers backed with a beard of white hairs, the length of staminodes and the hairs of styles. The somatic chromosome number of P. melanofilamenta is also reported as 2n = 36. 相似文献

Weber in having broadly lanceolate bracts, being 1–3‐flowered and possessing hairs on the upper part of the anthers where connected with the filaments; from P. sclerophylla (W. T. Wang) Yan Liu in having narrowly ovate to ovate leaf blade, leaf blade margin interrupted shallowly crenate, broadly lanceolate bracts, being 1–3‐flowered and possessing hairs on the upper part of the anthers where connected with the filaments; from P. shouchengensis (Z. Y. Li) Z. Y. Li in having narrowly ovate to ovate leaf blade, leaf blade margin interrupted shallowly crenate, broadly lanceolate bracts and possessing hairs on the upper part of the anthers where connected with the filaments. 相似文献

A new species of Gesneriaceae, Primulina debaoensis Neng Jiang & Hong Li, from Guangxi Zhuangzu Autonomous Region, China, is illustrated and described here. It resembles another endemic and stenochoric species in Guangxi, P. pungentisepala (W. T. Wang) Mich. Möller & A. Weber, but differs by having 12–18 or more leaves, leaf blade being broadly linear, oblanceolate‐elliptical or oblanceolate, bracts being ovate or elliptical with silvery or argenteous nerves and by having a yellow ovary that is 4–5 mm long and sparsely white pubescent. 相似文献

Primulina curvituba B. Pan, L.H. Yang & M. Kang, a new species of Primulina (Gesneriaceae) from Guangxi, China, is described and illustrated. This new species is mainly diagnosed by its strongly curved corolla tube, which is a rare character in Primulina. The morphological relationship and differences between this species and its related congeners are discussed. The conservation status of P. curvituba is assessed as ‘Critically Endangered’ (CR) according to IUCN. 相似文献

Wang and C. obtusidentata W. T. Wang, but differs by leaf blades ovate‐lanceolate, both surfaces sparsely strigulose; cymes 5‐ or 8‐flowered, bracts narrowly lanceolate, 6–8×1.5–2.0 mm; larger flowers (3.8–4.6 cm long), pink corolla, infundibuliform‐tubular tube; backside of anthers puberulous, filaments straight; staminodes glabrous, fused on the capitate top; stigma bipartite to the base with narrowly lanceolate lobes. 相似文献

Petrocodon multiflorus F. Wen & Y. S. Jiang sp. nov. (Gesneriaceae) is described and illustrated. It is most similar to P. dealbatus Hance, but can be distinguished by its leaf lamina texture, shape of leaf margins, and by the number of cymes borne by an individual plant and the number of flowers in each cyme. A key to the species of Petrocodon is provided. 相似文献

Primulina minor from the Daoxian county, Hunan province in China is described. This new species is similar to Primulina jingxiensis (Yan Liu, W. B. Xu & H. S. Gao) W. B. Xu & K. F. Chung and P. longzhouensis (B. Pan & W. H. Wu) W. B. Xu & K. F. Chung, but differs by its number of leaves (4–6), broadly ovate, orbicular‐ovate or orbicular leaf blade, 2–4 cymes, short peduncle (1.8–2.0 cm long), white (or white with light purple tinge) corolla, small corolla (8–10 mm long), 3 staminoides of which the lateral ones are short (0.75–0.90 mm long) and adnate to 1.6–1.7 mm above the corolla base. 相似文献

A new species of Primulina (Gesneriaceae) from a limestone area in southern China, P. rubella L.H. Yang & M. Kang, is described and illustrated. The new species has purple‐red flowers and is thus similar to P. lijiangensis, but differs by its petiole, leaf blade, cyme, filament, stigma and ovary. In adition, a molecular phylogenetic reconstruction indicated that P. rubella and P. lijiangensis belong to quite different clades. Instead, P. rubella appears to be closely related to the sympatric P. qingyuanensis, although these two species are obviously differentiated both in terms of flower color and other vegetative and floral characters. The conservation status of P. rubella is assessed as ‘Critically Endangered’ (CR) according to the IUCN red list categories and criteria. 相似文献
