aud 5 subquadrate ciliate lobes; glands | lin. in their greater diam,, 

 transversely oblong or subreniform, entire, "green" (Marloth) ; 

 ovary included; capsule with its base just exserted fruin the 

 involucre, ^ in. in diam., globose^ not angular or grooved, smootli,

 with spreading minutely bifid arms.

Described from a living plant sent to Kew by Mr. I. L. Drege, of Port 

 Elizabeth, in Aug. 1912. Called '* Voetangel" by the Dutch. 



149. E. cucumerina (Willd. Sp. PL ii. 886); stem apparently 



unbranched, 9-10 in. high, 1^ in. or more thick, eyhndric, appa- 

 rently 10-12-angled5 .succulent, spiny ; angles apparently very slii^htly 

 prominent and obtusely rounded, leafless ; spines (modified peduncles) 

 solitary, ^ in. (or more?) long; peduncles solitary, few at the apex 

 of the stem, as long as the spines, bearing 1 rather small involucre.

Western Region : Little Namaqualand, between Groene River and Koper 

 Berg, Le Vaillant. 



T6is plant is only known from Le Vaillant's figure, in which the peduncles are 

 represented as sometimes having two small spine-like branches, wliich may be 

 mtended to represent either setaceous or subulate bracts or spine-like branches 

 such as E. stelhvsjnna has. 



^_ 150. E. horrida (Boiss. Cent. Euphorb. 27 and in DC. Prodr. xv. 

 ii« 89) ; stem or stems probably erect, cylindric, 3^-41 in. in diam. 

 when driedj very deeply many- (in the specimen seen 14-) angled, 

 with the central solid part 1^-2 in. thick and the angles 1-1| in. 

 prominent, wing-like, 3-5 lin. thick at the base and 2|-3 lin. thick 

 at the margin in dried sections, with very numerous densely crowded 

 spines (modified peduncles) along their edges, glabrous ; main spines 

 stout, 4-10 lin. long and |-1 lin. thick at the base, very rigid, 

 straight, solitary, with shorter spines 2-4 lin. long about their base, 

 at first pul>erulous, finally glabrous; leaves not seen, probably 

 I'udimentary ; peduncles arising beside the bases of the spines, 

 2^-3 lin. long, bearing several bracts and 1 involucre, puberulous ; 

 bracts scale-like, |-1 lin. long, oblong, obtuse, more or less keeled 

 on the back, puberulous; involucre 2 lin. in diam., cup-shaped, 

 puberulous, with 5 glands and 5 rather large trans\ersely 

 rectangular or subquadrate finely toothed lobes; glands |-1 lin. 

 m their greater diam., transversely elliptic, entire; ovary and 

 capsule not seen.

Probably this plant is dioecious, as the involucres examined appeared to be male, 

 with a rudimentary ovarj', they are, however, immature. Drcge's specimens are 

 ^erj- hnperfect, consisting of sections and fragnieutss of the angles only.
