Fig. 5A

Type.

D.R. CONGO - Forestier Central • Kivu, Terr. Kalehe, km 110 route Kavumu-Walikale, réserve IRSAC à Irangi, riv. Fulonko ; 900 m; 6 Dec. 1956; Christiaensen 1918; holotype; BR [BR0000008261137] .

Habitat.

Dense rainforest in the water of the river [ Forêt ombrophile dense dans l’eau de la rivière].

Preliminary IUCN conservation assessment.

Critically Endangered: CR B2ab(iii) (possibly extinct). Amorphophallus margretae is only known from the type locality. The estimated AOO is 4 km² (assuming a 4 km² grid cell size). The habitat, a submontane rainforest, is under threat of illegal logging, and most of the area of the former Irangi Forest Reserve has been completely logged. Thus, the species might already be extinct.
