Polystichum wilsonii Christ

First recorded — Brause & Hieronymus (1910: 4) as Polystichum aculeatum auct. non (L.) Roth.

Note — Roux (2000: 56) did not list Rwanda in his “Distribution”, but in his paragraph “without exact locality”, he listed a specimen from “Karisimbi (versant sud) nr. Biuri, c. 3000 m, De Witte 1246 (BR)”, which is a locality in Rwanda.
