Holotype : — NIGERIA . Ogoja Province : grass plateau S escarpment, high forest, in soil, Ikwette-Balegette path, 29 December 1948 , H.Savory & R.W.Keay FHI25201 ( BM000785456 [digital image!]). Specimens seen:—Western Province: Nyungwe NP , road Pindura – border with Burundi , km 21, ± 1730 m , 27 July 1974 , J.Rammeloo 4082 ( FI065577 ); Cyamudongo Forest , c. 1900 m , S2°33`21.65`` E28°59`09.12`` , December 2021 , E.Fischer & B.Dumbo s.n. ( KOBL ) . First recorded for Rwanda : — Pichi Sermolli (1985: 135) . Habitat: —Terrestrial in montane forest, elev. 1700–1900 m . Distribution in Rwanda :—Western Province: Nyungwe NP, Cyamudongo Forest. Pindura – Bweyeye km 21. General distribution: —Africa: Nigeria , Cameroon , Gabon , D.R. Congo , Rwanda , Uganda , Angola . Note: — Pichi Sermolli (1985: 135) assigned the specimen Rammeloo 4082 clearly to this species: „I have compared both the specimens of Rammeloo 4082 with the holotype and paratype of A. gemmascens kept in BM; they are smaller in size, but, otherwise, they agree with this species in all its essential characteristics and thus I confidently refer them to A. gemmascens “. A search at Rammeloo’s locality was without result, as road construction work has destroyed part of the vegetation, but we found a second locality in Cyamudongo Forest.
