+ Selaginella tenerrima A. Br. ex Kuhn

New record — RWANDA: WESTERN PROVINCE: Nyungwe NP, Cyamudongo Forest, Forest floor or on wet rocks near streams and waterfalls in montane forest, 1732 m, 02°33'04.03''S, 28°59'48.58''E, 4 Apr 2021, E. Fischer s.n. (KOBL) .

Note — Roux (2009: 28) listed Rwanda under Selaginella tenerrima, albeit without mentioning a published record. Bizzari (1985) has recorded the species only in D. R. Congo and Burundi. Therefore, our collections from Rwanda represent the first definite record of the species.
