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

Abstract

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.

Oreocharis scutifolia (Gesneriaceae) , a unique new species from the Dry and Hot Valley of Jinsha River Basin, Yunnan, China

“…These characteristics set it apart from the aforementioned two species. Detailed literature reviews (Cai et al, 2017;2020a;2020b;2020c;2020d;Chen et al, 2013;2020;Chen et al, 2017;Guo et al, 2018;Han et al, 2017;Li et al, 2015;Möller et al, 2018;Pan et al, 2019;Truong et al, 2017;Wei et al, 2016;Wu et al, 1987;1991;Yang et al, 2015;Yang et al, 2019;Yang et al, 2015;Yi et al, 2019) and morphological comparisons with herbarium specimens confirm that this is indeed a unique and previously undiscovered species. Phylogenetic analysis primarily utilizing transcriptomes, has further confirmed its position within the genusOreocharis .…”

Oreocharis xieyongii, an unusual new species of Gesneriaceae from western Hunan, China

“…This genus contains ca. 139 species (125 plus new species recently published) that mainly occur in Northeast India, southern and southwestern China, Vietnam, Thailand, Myanmar ( Möller et al., 2011b , 2016 , 2017 , 2018 , 2019 ; Fu et al., 2019a , 2019b ; Pan et al., 2019 ; Wen et al., 2019 ; Yang et al., 2019 , 2020 ; Cai et al., 2019 , 2020 ; Chen et al., 2020b ; Du et al., 2020 ; Ling et al., 2020 ; Qin et al., 2020 ). In earlier taxonomic studies, the genus Oreocharis was thought to contain about 28 species ( Wang et al., 1990 , 1998 ), but after revision based on morphological and molecular evidence it now contains 11 previously recognized genera (i.e., Ancylostemon Craib, Bournea Oliv., Briggsia Craib, Dayaoshania W.T.…”
