curved at the base ; branch lets probably 8-4-angled, with a rather 

 small central solid part (split down the middle in the specimen seen), 

 divided by deep constrictions into many elliptic or orbicular segments 

 1-1^ in. long and l|-l|in. broad, glabrous ; angles wing-like, somewhat 

 sinuate- toothed and with a dark brown continuous horny border along 

 the margins. Leaves rudimentary, scale-like, soon deciduous. Spines

 Flowering eyes situated exactly midway between the spine-pairs. Flowers 

 and fruit unknown. — E. DekinJtii, Pax in Eng). Jahrb. xxxiv. 73, 875.

- This is allied to E. opuntioides, VVelw., but evidently lias more angles nnd the 

 spines are much stouter and longer. In E. opuntioides the flowering eyes are 

 1^-2 lin. above the spine iJairs, not midway between tliem, but below that point. I 

 have not seen a specimen of E. Dekindtii, Piix, which is referred by him to this 

 epecies, but from the description 'it would seem to belong here. 



153. E. infausta, N. E. Br. A succulent leafless spiny bush about 

 5 ft. high, glabrous in all parts. Branches 5-1 2 in. long, J-1 in. thick, 

 4-5- (rarely 6-) angled, with or without slight constrictions; angles 

 slightly compressed, usually even or but slightly tuberculate, with a con- 

 tinuous horny dark grey border less than 1 lin. broad, bearing pairs of 

 spines 1^-3 lin. apart ; spines subequal or unequal, 1-3^ lin. long, dark 

 grey or blackish. Cymes solitary in the axils of the spine-pairs, sessile, 

 subsessileor very shortly pedunculate, with 3 involucres, 2 on very short 

 branches. Bracts ^ lin. long, elliptic or suborbicular. Involucres sessile, 

 1|^-1^ lin. in diam., cup-shaped, with 5 glands and 5 transverse or broadly 

 cuneate fringed lobes; glands §-| lin. in their greater diam., transversely 

 oblong, entire. Ovary globose-trigonous, on a distinct pedicel nearly or 

 quite as long as the ovary, glabrous ; styles |-1 lin. long, united at the 

 base only and the united part exserted from the involucre, arms recurved- 

 spreading, with 2 small thickened lobes at the apex. Capsule \\ liri. in 

 diam., with its base just exserted from the involucre. Seeds | lin. 

 long, ellipsoid, with the inner face obscurely angular, marked with a 

 brown median line, minutely scrobiculate-tuberculate, greyi.sh-white. —

This has hitherto been associated with E. polyacantha, lioiss., and E. Thi, 

 Schweinf., but it distinctly differs from both in its ovary being as broad as long, 

 seated on a pedicel as long as itself, and the shorterstylcs are united at the biiseonly, 

 not to half-way up as in those species.
