Described from living plants and dried flowers sent to Kew by ilrs. Pater^on 

 and Mr, I, L. Drege. This species seems to have been founded bj Linnxus 

 entirely upon the figure in Conmielin's Priiludia Botanica, No specimen of it 

 exists in his Herbarium and probably he never saw the plant. Later authors 

 appear to have mistaken another closely allied species {E. Jimbriata, Scop.) for it. 

 But it is quite clear that Commelin's figure represents the Uitenhage and Port 

 Elizabeth plant, and not that figured by Berger (^Suklc. Euphorh. p. 91) as 

 E, nianimillaris, which is a native of a more westerly part of Cape Colony and is 

 commonly cultivated under that name. But the true E. mammillaris is a stouter 

 and softer plant, with more prominent and more hemispherical tubercles. The 

 synonymy above quoted belongs, I believe, to this plant, but the following may 

 partly belong to E. Jimbriata, Scop., but it is now quite impossible to determine, 

 yiz,~E, mammillaris, Mill, Gard. Did, ed. viii. no. 8 ; Thinih. Prodr. 86, and 

 Fl. Cap, ed, Schult. 403 ; Ait. Ilort. Kew, ed. 1, ii. 134 ; Haiv. Syn, PL Succ. 12S. 



Of E. mammillaris I have seen both male and female involucres in a dried state, 

 but only the male preserved in fluid. When dried flowers are boiled for dissection, 

 the male is decidedly much larger than the female and its glands appear to be of a 

 ^uch paler and possibly greenish colour. I have found both unisexual and 

 bisexual involucres on the same plant, but do not know if this is always the case.

A yonng plant sent to Kew by Mr.s. Paterson indicates that the seedling first 

 ^^ms a globose stem about 1 in. in diam., from which arise the numerous 

 cylindric erect stems that ultimately form the clump-like growth of the plant.
