Loxostigma hekouensis (Gesneriaceae), a new species from Yunnan Province, China

Ann. Bot. Fennici  54: 429-433

ABSTRACT

A new species of Gesneriaceae, Loxostigma hekouensis Lei Cai, G. L. Zhang & Z. L. Dao, is described and illustrated from Hekou County, southeastern Yunnan Province, China. It is most similar to L. glabrifolium in the shape and colour of the flower but differs in the shape and indumentums of the calyx. It also resembles L. fimbrisepalum in the shape of the calyx, but it can be easily distinguished by the shape and colour of the flowers(Cited from Cai et al., 2017).
