598 cxxii. EUPiiORBiACE^ (brown). [Eiiphorhia. 



Flowering-eyes touching the shields, producing 2-3 cymes with peduncles 

 2-3 lin. long, each bearing 3 involucres, with the lateral on branches 1 J- 

 2J lin. long, glabrous. Bracts membranous, suborbicular, about Ijlin. 

 in diam., obtuse or apiculate, entire or minutely denticulate, glabrous. 

 Involucre subsessile or very shortly pedunculate, 3^-4 lin. in diam. and 

 1^ lin. deep, shallowly cup-shaped, glabrous, with 5 glands and 5 short 

 transverse fringed lobes; glands contiguous, about If lin. in their 

 greater diam., reniform or transversely oblong, entire, unequally 2- 

 lipped or with the inner margin turned up. Ovary subses.sile, only 

 partly exserted from the involucre, glabrous, with a calyx of about 

 5 filiform segments §-1 lin. long ; styles 1 lin. long, united at the base, 

 thickened and 2-lobed at the apex. Fruit and seeds not seen.

185. E. garuana, H. E. Br. A succulent leafless spiny bush, 

 grown as a hedge plant, about 6 ft. high, probably attaining much 

 larger dimensions and perhaps becoming a tree. Bianch of the speci- 

 men seen 10 in. long, 1 in. (and probal^ly more) in diam., con- 

 stricted into 5 oblong or narrowly elliptic segments 1J-2J in. long, 4- 

 angled, with the solid central part about as thick as the wing-like angles 

 are broad ; angles not toothed or sinuate at the margins. Spines 1-1 i 

 lin. long, in pairs, diverging, with or without a pair of minute auricles 

 (not prickles) at their base and almost touching them, blackish-brown, 

 on small subhorny broadly obovate blackish-brown (possibly discoloured 

 in drying) shields 2-3 lin. apart, apparently deciduous. Flowering- 

 eyes touching the spine-shields, pioducing 1-3 cymes on peduncles 

 4-4A lin. long, bearing 3 involucres, with the central male and the 

 lateral bisexual, glabrous. Bracts suborbicular, about 2 lin. in diam , 

 very concave. Involucres 3-3 J lin. in. diam. when fully developed, 

 about IJ-lJ lin- deep, broadly and shallowly cup-shaped, glabrous, 

 with 5 glands and 5 subquadrate deeply fringed lobes ; glands con- 

 tiguous, l|-2 lin. in their greater diam., transverse, somewhat half- 

 circular, entire, apparently deflexed at the ends. Ovary (very young, 

 only seen in very immature bisexual involucres) glabrous, with a 

 calyx at its base, cut into several filiform segments ; styles 3, rather 

 more than 1 lin. long, probably longer when mature, very shortly 

 united at the base, stout, bifid at the apex. Capsule and seeds not seen.

The spine-shields of this species are softer and less liorny than in any other I have 

 seen; also tliey nppear to be quickly deciduous from all hut the one or two terminal 

 segments of the branches. 



186. E. Candelabrum, Tremaux ex Kotschy in Mittheil. Geogr, 

 Gesells. Wien, i. Ahhandl. \^Si [extract, Allgem. Ueberhl. Nilldnd, 13). A 

 tree 25 ft. high, with a short trunk of hard wood up to 3 ft. in diam., 

 divided into a mass of crowded branches forming a dome-shaped crown 

 20-25 ft. in diam. Branchlets fleshy, 3-5- (often 4-) angled, con- 

 stricted at intervals and 1-1 J in. broad across each face, glabrous, green ; 

 angles slightly compressed, but not wing-like, with shallowly concave
