This species is very close to Eriosema verdickii var. schoutedenianum[
Eriosema schoutedenianum auct.
Eriosema lebrunii is a decumbent, perennial plant, producing one to several slender, sparsely branched stems 10 - 30cm tall, from a globose or turnip-shaped tuber that is around 30mm x 15mm[
The plant is harvested from the wild for local use as a food
Tropical Africa - Nigeria, Cameroon, eastern DR Congo, Rwanda, Burundi, Tanzania, Malawi, Zimbabwe, Mozambique
Savannah, clearings, rocky ground, pastures, secondary grassland, marshy grasslandd, roadside edges, bare clayey soil; at elevations from 1,500 - 2,400 metres[
This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
]. The globose tuber is 20 - 30mm x 15mm[
Like many species within the family Fabaceae, once they have ripened and dried the seeds of this species may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[
