Raphionacme velutina is a small much-branched perennial herb. The stems and leaves are densely covered in short, velvety hairs. They exude a milky latex when receiving surface damage. The specific name of velutina (Latin) indicates this velvety feature.

The stems grow from an underground tuberous rootstock. The leaves are simple, narrowly ovate and folded in along the whitish to pale brown midrib. Leaf colour is grey-green to blue-green. Leaves taper to pointed or rounded tips and have entire margins.

The distribution of this plant lies in the Northern Cape, the Free State and North West, as well as in Lesotho, Botswana and Namibia (Germishuizen and Fabian, 1982).
