 First recorded for Rwanda: — Pichi Sermolli (1985: 124) as Loxoscaphe theciferum var. concinna (Schrader 1818: 918) Kuhn (1879: 36).   
 Habitat: —Epiphyte in montane forest, also outside the forest, e.g., on roadside trees, elev. 1750–2500 m.   
 Distribution in Rwanda:—Northern Province: Volcano NP. Western Province: Gishwati-Mukura NP, Nyungwe NP. Southern Province: Huye Arboretum, Butare. Eastern Province: Akagera NP.   
 General distribution: —Africa: Cameroon to Ethiopia, southwards to Rep. South Africa, Swaziland, Madagascar. Also in the Mascarenes and Comoros.   
 Note: — Viane (2021: 203) considers this taxon to be a species of its own, Asplenium concinnum (Schrad.) Kuhn (1868: 99). Further studies are required to solve this problem. In the case that both species are recognized, A. theciferum s.str. would be restricted to America (Mexico to Bolivia).
