It contained a number of morphologically similar and variable species in southern Africa.

[3] Plants start off herbacoues with virgate growth form (erect, rod-like stems) and become increasingly woody and often decumbent (branches grow along the ground but turn up towards the ends) with age.

The leaves are linear or lance shaped and often have roughly hairy margins.

It is found in Botswana, Burundi, Eswatini, Kenya, Lesotho, Malawi, Mozambique, Rwanda, South Africa, Tanzania, Zambia, and Zimbabwe.
