| Abstract: |
| Clematis tongluensis, a species distributed in Nepal, Bhutan, Northeast Indida and Bangladesh, was discovered this summer from Southeast Tibet Autonomous Region of China. This species is related to Clemateis montana Buch.-Ham. ex DC., differing from the latter in its oblong sepals caudate-acuminate at apex and hairy adaxially, glabrous abaxially. In C. montana, the sepals are obovate, at apex rounded, and glabrous adaxially, puberulous abaxially. |
