Begonia subfiliformis is a new species of Begonia section Coelocentrum found in the karst region of southwest Guangxi, China. It has yellowish-green flowers and glandular inflorescences. Morphologically, it is similar to B. filiformis, but differs mainly by larger stipules with hairy or nearly glabrous dorsal ridge, adaxial leaves sparsely short-hispid and adorned with whitish-green patches or ring-shaped belt, larger basal bracts, larger staminate flower and tepals, and more stamens. Due to the current data, the new species is assigned to Endangered (EN) according to Guidelines for Using IUCN Red List Categories and Criteria. |
