This member of the Fabaceae family was
given this name by Rudolf Wilczek in 1954. It is found in grassland
and swamps of Dem. Rep. Congo, Tanzania and Zambia, growing in a well
drained soil or even swamp with lots of water and some to lots of sun. The
caudex can grow to 14 centimetres, while the annual stems reach 50
centimetres height. The flowers are purple with a greenish outside,
the immature fruits slightly pubescent.
The subspecies; Dolichos
bianoensis subsp. orientalis are only found in Congo. It
has relatively shorter and broader acuminate leaflets. |
