Notes.

The species has already been illustrated by Fischer and Killmann (2008). Dhetchuvi (1996) cites a specimen of Aframomum zambesiacum from Rwanda, Eastern Province, Parc National de la Kagera, colline Rurama, 3 Nov. 1958, Troupin 8698 (BR0000024588621) but this proved to be Aframomum angustifolium .

Excluded species

Harris and Wortley (2018) cite Aframomum alboviolaceum (Ridl.) K.Schum. from Rwanda with the specimen Froment 525 from Kibali (BR0000021390890). However, this specimen was collected at Kibali (Mahagi) by D. Froment on 11 June 1959 in a Loudetia savanna in the Democratic Republic of the Congo, phytogeographical district Lac Albert, and has thus to be excluded from the Flora of Rwanda.
