Later, +Smith and Wasshausen (1984) +described this plant and validly published it. According to the location and coordinates provided in the original documents and collecting record of all collected specimens, it has been only found in northern +Myanmar +adjacent to the border to +Xizang +( +Tibet +) Autonomous Region of +China +. POWO (http://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:903683-1) recorded it is also distributed in SE +Xizang +, but there is no exact collection evidence to support. Therefore, our collection should be the first time of this species collected from +China +. Due to the imperfection of the +type +specimens, lacking stipules and female flowers, Smith and Wasshausen didn’t describe these parts and considered the inflorescence as unisexual. We added the characteristics description of these parts and corrected its gender as monoecious. + + + +Begonia hymenophylloides + +is similar to + +B. garrettii +Craib (1930) + +(= + +B. arboreta +Y.M.Shui (Shui 2002: 307–308) + +( + +Chen +et al. +2018 + +)). Both are epiphytic on trees, and have globose tuber and simple leaf. However, the former can be easily distinguished from the latter by its smaller (14–15 × +14–17 cm +vs. 17–29 × +8–12 cm +) leaf adaxially bullate and densely hairy, abaxially hairy (vs. both sides glabrous) along veins, ovary densely villous (vs. glabrous). + + + + \ No newline at end of file
