Deinostigma fasciculatum, a new species of Gesneriaceae in Yunnan, China.

ABSTRACT: A new species of Deinostigma (Gesneriaceae) from Yunnan, China, Deinostigma fasciculatum W.H.Chen & Y.M.Shui, sp. nov., has been discovered and described. In the genus, the new species is similar to D. cicatricosum (W.T. Wang) D.J. Middleton & Mich. Möller and D. cyrtocarpum (D. Fang & L. Zeng) Mich. Möller & H.J. Atkins in dark purple flowers and falcate fruit, but differs from them mainly in the inflorescences with fasciculate flowers, calyx lobes (reflexed, narrowly lanceolate and 1.2-1.3 cm long), corolla tubes (sharply contracted below middle and white outside and below throat). The above three species grow nearby non-limestone wet cliffs and geographically isolated with different distributions (the new species in Southeast Yunnan, D. cicatricosum in Eastern Guangxi and D. cyrtocarpum in Southern Guangxi and Guangdong, China).

Four new species of Oreocharis (Gesneriaceae) in Yunnan province, China.

Project description:Four new species of Oreocharis (Gesneriaceae) are described and illustrated. These new species grow in pairs in montane forests in Yunnan province, China. One pair grows in Wenshan county, Southeast Yunnan, viz. Oreocharis eriocarpa W.H. Chen & Y.M. Shui and O. wenshanensis W.H. Chen & Y.M. Shui and another pair grows in Yongde county, Southwest Yunnan, viz. O. fulva W.H. Chen & Y.M. Shui and O. lacerata W.H. Chen & Y.M. Shui. Their morphological and geographical relationship with similar species is discussed and the IUCN endangered status is provided, based on the available data.

Oreocharis wumengensis, a new species of Gesneriaceae from northeastern Yunnan, China.

Project description:A new species of Gesneriaceae, Oreocharis wumengensis Lei Cai & Z.L.Dao from Wumeng Mountain area, Yanjin County, Yunnan Province, China, is described. The new species is morphologically similar to O. panzhouensis Lei Cai, Y.Guo & F.Wen in the shape of corolla, number of stigma and stamens, but it can be easily distinguished from this species by the leaf shape and indumentum characters of leaf blade, calyx and stamens. Detailed descriptions with photographs of the plant and holotype, and comparisons with morphologically similar species, are also provided.

Aeschynanthussmaragdinus F.Wen & J.Q.Qin (Gesneriaceae), a new species from Yunnan Province, China.

Project description:Aeschynanthussmaragdinus F.Wen & J.Q.Qin, a new species of Gesneriaceae from the monsoon rain forest in Mangbang township, Tengchong City, Yunnan Province, China, is described and illustrated here. It morphologically resembles A.chiritoides C.B.Clarke in size, shape and hairs on the leaf blades. But it can easily be distinguished from the latter by the green corolla limb with brownish-red to maroon lower lobes. At the same time, the hairs of the pedicel and calyx lobes, the length of the staminode and the size of the seed grain can also help distinguish both. It is provisionally assessed as Data Deficient (DD), according to the IUCN Red List Categories and Criteria, because field surveys for this new taxon have not been completed.

Two new species of Allocheilos (Gesneriaceae) from the karst regions in Yunnan, China.

Project description:Allocheilos W.T.Wang in Gesneriaceae was described in 1983 and is characterized by its 4-lobed adaxial lip and undivided abaxial lip with acute apex. The genus is endemic to the karst regions in southwestern China and is classified as endangered due to habitat loss. During surveys of the karst areas in Yunnan of southwestern China in 2017, we collected two unknown species of the genus and later confirmed their novelty to science based on the detailed observation of their morphological characteristics, viz. A. maguanensis W.H.Chen & Y.M.Shui and A. rubroglandulosus W.H.Chen & Y.M.Shui. Their relationships with the similar species and provisional conservation status are discussed.

Oreocharis oriolus, a new species of Gesneriaceae in a sclerophyllous oak community from Yunnan, Southwest China.

Project description:Oreocharis oriolus, a new species of Gesneriaceae in a sclerophyllous oak community from Yunnan, Southwest China, is described and illustrated. Morphologically, it resembles both O. forrestii and O. georgei, while it is distinct in combined characters of wrinkled leaves, peduncle and pedicel covered with whitish and egladular villous hairs, bract lanceolate and nearly glabrescent adaxially, and staminode absent. Molecular phylogenetic analysis based on nuclear ribosomal internal transcribed spacer (nrITS) and chloroplast DNA fragment (trnL-F) of 61 congeneric species also supported O. oriolus as a new species while it was nested with O. delavayi. It was currently assessed as 'Critically Endangered' (CR) regarding to its small-sized population and narrow distribution following the IUCN categories and criteria.
