Indigofera rhynchocarpa is a shrub with straight, branched stem; it usually grows 50 - 200cm tall, though sometimes flowers on short coppice shoots[
The plant is harvested from the wild for local use as a medicine.
Tropical Africa - Ghana, through southern Chad to Uganda and northern Tanzania, south to Angola, Zimbabwe and Mozambique
Brachystegia, Julbernardia or Uapaca woodland often with tall grass annually burned; wooded grassland; bushy wooded places; thickets with tall herbage; savannahs; margins of seasonally wet or riparian woodland[
Indigoera species generally grow best in a sunny position, preferring a well-drained but moist soil[
]. Many of the species will also succeed in drier conditions and in poor soils.
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.
A decoction of the roots is used as a vermifuge in the treatment of threadworm infections[
Like many species within the family Fabaceae, once they have been dried for storage 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[
