S. lepidotum was described from imperfect material (Hopfner, 118, and Newton,. 

 33) and distinguished chiefly by the dense mealy glandul«r covering on both sides of 

 the leaves. It agrees in this respect with Welwitsch's specimen, 1661, at Kew. 

 The typical form occurs also in extratropical South Africa.
