Plant Ecology and Evolution 146 (2): 203–211.

ABSTRACT

A new species, Anna rubidiflora S. Z. He, F.Wen & Y.G.Wei, a stenochoric species from the southern part of China (Kaiyang county of Guizhou province), is described and A new species, Anna rubidiflora S. Z. He, F.Wen & Y.G.Wei, a stenochoric species from the southern part of China (Kaiyang county of Guizhou province), is described and illustrated. It differs from the morphologically similar species A. ophiorrhizoides (Hemsl.) Burtt & Davidson by being a larger plant with undivided stem, its entire leaf blade margins, its abaxial greenish-white leaf blades with slightly purple nerves, its obovate-lanceolate calyx lobes with truncate and nearly rounded apex without nerves, and its reddish-purple corolla. The newly described species is illustrated both by a line drawing and photographs. A locality and distribution map is also presented. A phylogenetic analysis confirmed that A. rubidiflora is a member of Anna and a close relative of A. ophiorrhizoides.

ABSTRACTPrimulina lutvittata Fang Wen & Y.G. Wei, a new species of Gesneriaceae from Guangdong, China, is described and illustrated. It is morphologically similar to P. fengshanensis , but differs by several characters of the leaves, cymes, bracts, corollas and anthers.

No. 3 Wei-Bin Xu, Yan Liu, Yoshiko Kono, Hsuan Chang, Ching-I Peng & Kuo-Fang Chung: Primulina cardaminifolia (Gesneriaceae), a rare new species from limestone areas in Guangxi, China.
Botanicals Studies, 54: 19-28.

ABSTRACTBackground: Primulina cardaminifolia Yan Liu & W.B. Xu (Gesneriaceae), a distinct new species with imparipinnate leaves, is described and illustrated from a limestone valley in Guangxi Zhuangzu Autonomous Region, China. To assure its generic placement and phylogenetic affinity, phylogenetic analyses were performed using DNA sequences of nuclear ITS and chloroplasttrnL-F intron spacer region. Additionally, somatic chromosome number was counted and pollen stainability was tested.

Results: Phylogenetic analyses support its placement in Primulina; however, two phylogenetically distinct ITS sequence types were detected, suggesting a probable hybrid origin. Its pollen stainability is 100% and its chromosome number, 2n = 36, is congruent with all known counts of diploid species of the genus.
Conclusion: All available data support the recognition of the new species Primulina cardaminifolia and suggest that it could have derived from homoploid hybrid speciation. Color plates, line drawings and a distribution map are provided to aid in identification.

Phytotaxa 131 (1): 29–34.

ABSTRACTOreocharis glandulosa, a new species of Gesneriaceae from southern Yunnan, China, is here described and illustrated. It is similar to O. bodinieri in its corolla shape, but can be easily distinguished by its dense glandular pubescence on the outside of the corolla, the limb distinctly two-lipped, the adaxial lip bilobed to near base, the lobes ovate to triangularovate, the abaxial lip trilobed to the base, the included stamens, the glabrous anther connectives and the ring-like, glabrous, entire or subentire disc.

Guihaia 33(5): 591–598.

ABSTRACT

A new species of Gesneriaceae, Primulina beiliuensis B.Pan & S.X.Huang from limestone areas in Guangxi, China, is described and illustrated here. The new species is morphologically similar to P. lutea (Yan Liu & Y.G. Wei) Mich. Möller & A. Weber in its habit and leaf form, etc., but easily differs the latter in its leaf blades broadly ovate, base nearly cordate, margin shallowly obtuse-dentate or shallowly undulate-serrate, corolla purple, corolla, peduncle, bracts and calyx lobes outsides, pedicel with purple pubescence. Molecular evidences hint that it is systematically similar to P. repanda var.guilinensis (W.T. Wang) Mich. Möller & A. Weber, but the morphologies of two relatives are obviously different.
