Begonia sikkimensis is a species of flowering plant in the family Begoniaceae, native to Tibet, Nepal, the eastern Himalayas, Assam, and Myanmar. With its highly dissected leaves it resembles Begonia U614, but that as yet undescribed species is rhizomatous, and Begonia sikkimensis is caulescent.

Probably Begonia U614, probably sold as Begonia sikkimensis
