on old parts, the bark seems to separate into 4-5 ribbon -like strips, 

 bearing pairs of spines without spine-shields scattered along them, 

 <da])rous, brown, becoming dark grey. Leaves rudimentary, minute. 

 Spines i-1 lin. long, in pairs J-^ in. apart, slightly diverging, recurved, 

 dark brown or dark grey. Flowering-eyes in the axils of the sjiine- 

 pairs. Involucres i» together, sessile or subsessile, with the middle one 

 usually male, 1 l-lf lin. in diam., obconic-cup-shaped, glabrous, with a 

 spreading subtruncately 4-r)-lobed glandular rim about h lin. broad, the 

 <dands being united at the basal part, surrounding 4-5 erect broad 

 transverse fringed lobes. Ovary (young) subsessile, glabrous; styles 

 5 lin. long, free, slender, filiform, entire at the apex. Fruit not seen. —

14o. E. EUenbeckii, Pax in KikjI. Jaltrh. xxxiii. "1^'). A leafless 

 spiny succulent of unknown habit. Stems or branches of the type 

 specimen 2-2^, in. long and 5 lin. thick, but probably stouter when 

 alive, apparently cylindric, with about spiral series of grey shield- 

 shaped spine-shields on very slightly raised tubercles. Leaves not seen, 

 doubtless rudimentary. Spines 4 on each spine-shield, arranged nearly 

 in a transverse line, with the 2 outer 1-1 J lin. long and the 2 inner 

 :\-\) lin. long, slender, greyish. Flowers and fruit unknown. — Pax in 

 Engl. Jahrb. xxxiv. 81.

144. E. inaequispina, X.?J. Br. Probably dwarf and branching, 

 succulent, leafless, very spiny. Branches cylindric, \-\ in. thick when 

 dried, covered with crowded roundish or obovate horny spine-shields 

 1-1 J lin. long, each bearing a pair of spines, at first brown, soon 

 becoming grey. Spines very unequal, some pairs scarcely more than 

 Jj in. long, others up to § in. long, all needle-like, straight, horizontally 

 spreading, not very diverging. Leaves very rudimentar}-, minute. 

 Flowers and fruit not seen.

Although the spcchncn is incomplete, the cylindric stems, crowded shields, and 

 lonfr unequal spines, readily distinguish this from all other known species except 

 E. Elleiilieckii, from which it differs in the spine-shields not bejng 3-lobed, and an 

 entire absence of a pair of prickles at the base of the spines. 



145. E. golisana^ X. K. Br. Perennial, succulent, spiny, leafless, 

 about o in. high, witli stout fibrous roots. Stems erect, branching, 

 densely crowded, J-| in. thick, several-angled, glabrous; angles with 

 continuous horny dark brown margins, laised into closely set small 

 tubercles, each bearing a pair of needle-like dark brown spines J-i in. 

 long. Leaves none or very minute. Peduncles solitary in the axils of 

 the spines, about 1 J lin. long, slender, ?>• or fewer-flowered, glabrous. 

 Bracts scarcely | lin. long, oblong, toothed at the apex, glubrous. 

 Involucres shortly pedunculate or subsessile, about 1 lin. in di;im., 

 obconic, glabrous outside, with 5 glands and 5 subquadrate lobes fringe-
