123, E. tuberculata (Jacq. Hort. Schoeubr. ii. 43, t. 208) ; 

 succulent, 11-2 ft. high, with numerous branches fi-om a thick 

 rootstock or main stem "svhoUy or partly buried in the ground, 

 spineless, but the branches beset with the hardened persistent 

 remains of the peduncles, not true spines, only dried brandies seen, 

 3-18 in. long, |-| in. thick, evidently stouter when alive, unbranched, 

 cylindric or slightly thickened upwards, erect, covered with rhom- 

 boid conical tubercles 3-4 liu. long, 1-3 lin, broad and 1-3| lin. 

 prominent, glabrous; leaves J-2 in. long, f-l^ lin. broad, linear, 

 channelled dow^n the face from incurved margins, acute, soon 

 deciduous, glabrous, somewhat fleshy ; peduncles solitary in the 

 axils of the tubercles at the tips of the branches, persistent and 

 hardening, at first |-| in. long, apparently elongating as the fruit 

 ripens up tu 1| in. or perhaps more, bearing about 4 bracts and 

 1 involucre at the apex, glabrous; bracts H-2 lin. long and 1-2 

 lin. broad, elliptic or elliptic-ohovate, obtuse, concave, glabrous, 

 ciliate ; involucre 5-7 lin. in diam,, broadly bowl-shaped, glabrous 

 outside and within, w-ith 5 glands and 5 subquadrate toothed or 

 nearly entire and minutely ciliate lobes ; glands closely sessile on 

 the cup of the involucre, U-2| lin. long, l|-3 lin. broad at the 

 tips, broadly cuneately palmatifid, divided to half-way down into 

 3-6 linear spreading processes, recurved at the tips, slightly dilated 

 , or once or twice shortly bifid at the apex, glabrous, green and not 

 pitted on the undivided or glandular part and the processes white ; 

 ovary sessile, quite included in the involucre, thickly pubescent 

 with erect stiffish or somewhat bristle-like hairs ; styles exserted, 

 2f-3 lin. long, united nearly to the apex, with very short slightly 

 spreading thickened or bifid tips ; capsule not seen. Willd, Sp. PL

Tbe tubercles and leaves as represented by Jacquin are larger than on wild 

 specimens, from which the measurements above given are taken. 



With regard to the specsimens distributed by MacOwan as coming from Cannon 

 Hill, that locality is undoubtedly an error, and I have no doubt the specimens 

 "^ere really collected near Clanwilliam, an opinion that is confirmed by the 

 presence of pieces of E. Macmcani, K. E. Br,, mixed with it on all the sheets of 

 this distribution that I Iiave seen, as the latter species has only been collected at 

 Cianwilliam-
