B C.Jeffrey, Fl. Zambes.: 450. 1978. Coccinia sp. B Zambia. Southern Province: Mazabuka, on Nanga Estate near Kafue pilot polder [c. 15°45'S , 27°54'E ], female, fl, 7 Mar 1963, H.J. van Rensburg 1620 (K!). Distribution. Only known from single collection. Remarks. Like Coccinia sp. A, Jeffrey (1978) suggested a closer relationship to Coccinia barteri . The tubular corolla and the coriaceous leaves support that. The collection was found in riverine bush in Acacia woodland and Hyparrhenia / Setaria grassland in a flood plain area, which is unusual for Coccinia barteri as it rather occurs in (rain) forests. White (1983a) calls the phytochorion of that region "edaphic grassland with semi-aquatic vegetation". On the one hand, the local soil conditions are not known, and water might be available throughout the year, on the other hand this individual might also represent a local adaptation towards increased drought tolerance.
