 Hope. Stapelia lentiginosa, Curt. bot. mag. t. 505. Ait. hort. 

 kew. ed. ','d. vol. 2. p. 97. Stems branched at top. This 

 species agrees with H. guttata, in the colour and form of the 

 flowers ; but in H. guttata the peduncles are longer, rising from 

 the base of a simple stem, and having the tubercles or teeth 

 of the branches not hooked ; and the spots on the limb of the 

 corolla are larger.

 of the Cape of Good Hope. Stapelia crispa, Hort. This is 

 very distinct from both H. barbata and H. tubata, but is 

 perhaps only a monstrous variety of one of them. The teeth of 

 the branches are smaller than in any other species.
