181. E. parvimamma (Boiss. in DC. Prodr. xv. il. S^ and 92 



under E. pugniformis) ; steni very short, fleshy, thickened at the 

 obcouic apex, producing numerous short stellately radiating 

 branches scarcely 2 in. long ; tubercles minute, depressed^ roundish- 

 ovate, crowded, 2-3 lin. long (breadth and prominence not stated) ; 

 leaves scarcely Ih lin. long, ovate-spa thulate, mucronate. Flowers 

 unknown.

South Africa : without locahty, originally described from a cultivated plant of 

 which nothing more is known. 



So far as I have been able to ascertain, no specimen of this species exists in the 

 Boissier or any other Herbarium. But between 1866 and 1870, in the collections 

 of air. T. Cooper and Mr. W. Wilson Saunders, I saw plants cultivated under the 

 name of F, par ri mamma ^ which I now recognise to have been F. iiievmis, Mill., 

 and to a certain extent Boissier's descrij^tion agrees with that species, but as he 

 states that the branches are scarcely 2 iu. long, whilst in E. inermh (especially 

 under cultivation) they are usually much longer than that, I think It cannot have 

 been E. ineiims that he was describing and, therefore, the identification of 

 F. parvimamma must remain doubtful. However, it cannot possibly have been 

 the plant Btrger has described as E. parvimamma, since the latter has long 

 branches, with larger tubercles and leaves twice as long as those of Boissier s 

 plant. 



182. E. procumbens (Mill. Gard. Diet. ed. viil no. 12); dwarf, 



succulent, spineless; main body of the plant not morethan 3 in. 

 high ; branches spreading on the groundj seldom more than 6 in. 

 long, with square tubercles, leafless ; flowers not described. Medusea 

 procunibens^ Haw, Syn. PL Succ. 134, excL reference to Burniann ;

South Africa : originally described from cultivated plants. 



Nothing is known of this plant he^^ond the imperfect descriptions of ;Miiler and 

 Haworth, given above. The plant that has been supposed to be this species is 

 E. pasea, N, E. Br,, which see. 



183. E. Haworthii (Sweet, Hort. Brit. ed. i. 356, not of 357) ; 

 stem or branches succulent, spineless, tuberculate ; leaves linear- 

 lanceolate ; peduncles pubescent, pei^sistent ; bracts cuneate-obovate, 

 subentire ; glands of the involucre (described as petals by Baworth) 

 pectinate-serrate. Treisia Clara, Haw. Syn. PL Succ. 131, e:^cl

As Haworth describes the glands of the involucre as being toothed, the plant 

 lad could not have been E. Clara of Jacquin, which has entire ghuuls. 



Excluded species. 



E. spartioides (Jacq. Hort Schoenbr. iv. 44, t. 486) ; by some 

 error this is stated by Jacquin to be a native of South Africa, but 

 the plant represented by him is merely a form of B. Cupani, Guss., 

 a native of Sicily.
