wing-like angles 1-2^ in. broad and 1 lin. or more thick and a small 

 solid central part scarcely ^ in. in diam. when dried, apparently very 

 glaucous, with the angles mure or less sinuate and somewhat wavy, and 

 with a continuous horny light brown margin. Spines 2-^) lin. long, in 

 pairs, diverging, with or without a very minute pair of prickles at their 

 base, light brown with darker tips. Leaves rudimentary, scale-like, about 

 J lin. long and 1 lin. broad, transverse, somewhat semicircular, wavy or 

 crisped. Cymes subsessile or very shortly pedunculate, several together, 

 forming dense clusters, each composed of 9-18 involucres, crowded along 

 the angles of the terminal branches. Involucres about "dh lin. in diam., 

 cup-shaped, glabrous, with 5 glands and 5 transversely oblong minutely 

 toothed lobes; glands contiguous, 1| lin. in their greater diam., trans- 

 versely oblong or elliptic-oblong, somewhat 2-lipped when dried, entire, 

 yellow. Ovary subsessile, included in the involucre, with a small 

 cupular or rim-like calyx at its bnse, glabrous; styles Ij lin. long, 

 united at the basal half, then spreading, with minutely 2-lobed or rather 

 channelled stigmas. Capsule and seeds not seen.

1G6. E. ussanguensis, iV. E. Br. A succulent spiny leatiess tree 

 25-30 ft. high, with a small crown. J^ranches strongly constricted at 

 varying intervals, forming ovoid-conical segments li-4i in. long, 3-4 in. 

 or more in diam., broadest at the base, a-angled, with a small central 

 solid part, glabrous, green ; angles broadly wing-like, much compressed, 

 about J in. thick, with continuous horny brown margins having 

 peculiar fold-like sinuations midw ay between the pairs of spines. Leaves 

 not seen, probably scalt^-like. Spines 1-4 lin. long, in p-irs J-| 

 in. apart, stout, not very divergent, blown. Flowering-eyes in the 

 sinuations, J-J in. above the spine-pairs. Cymes sessile, very crowded 

 along the angles at the ends of the branches, each with 3 sessile invo- 

 lucres, glabrous. ' Bracts 1 1-2 lin. in diam., suborbiculaj-, concave, thin. 

 Involucres J in. in diam., cup-shaped, glabrous, with 5 glands and 5 

 cuneately subquadrate truncate denticulate lobes ; glands contiguous, 

 IJ lin. in their greater diam., transversely elliptic or rather narrowly 

 oblong, 2-lipped, entire, decurved at each end. Ovary ses>ile and 

 together with the united part of the styles included in the involucre, 

 with a very small cupular shortly 3-lobed calyx at its base; styles about 

 IJ lin. long or less, united for half their let.gth, spreading above, with 

 thickened entire minutely tubercnlate stigmas.— E. yyikce. Pax in

Tliis is dosely allied to E. confroversa, N. E. Br., but differs in the foltl-like 

 sinuations of the angles Jind in having very short tooth-like (not long and linear) 

 calyx-lobes under the ovnry.
