This member of the Polygonaceae family was given this name by Carl Lebrecht Udo Dammer in 1895. It is found in Congo, Angola, Burundi, Kenya, Malawi, Tanzania and Za´re, growing in open areas and open woodland with a sandy soil. The branched stem can reach half a meter while the woody rootstock can reach ten centimetres or more. The flowers are greenish white. This species shows considerable variation in leaf shape and in the hairiness of the leaves. In general, the fruits are the key for identification of this genera.

The genera name means 'sharp-angled'. The species name is named after Franz Ludwig Stuhlmann, 1863-1928, a German naturalist, zoologist and African explorer.
