lint it is quite possible tliat wiieii tlie female invohicrps of E. grandicornis are 

 developed :i peduncle may also develop, and that when better known E. breviarti- 

 culata will prove to be identicid with the latter sprcies. 



158. E. Wakefieldii, X. E. Br. A succulent leafless spiny 

 brciiiching perennial, with jstout fibrous roots, glabrous. Branches 

 o-angled, \-}j in. in dinm. when dried; angles compressed, with deltoid 

 acute teeth or lobes \-\ in. apart, without horny margins, bearing at 

 their apex a pair of divergit)g blackish spines 1^-2 lin. long, which 

 have 2 very minute points ac their base. Flowers and fruit not seen.

159. E. Robecchii, Pax in A nn. Istit. Bot. Roma, vi. 186. A succu- 

 lent leafless spiny much-branched shrub (or tree ?). Branches and branch- 

 lets in distant groups or .«omewh;it whorled, acutely 8-angled and more 

 or less twisted, ^-1 in. in diam. ; branchlets very much recurved ; angles 

 acute, toothed; teeth j-lj in. apart, l|-2 lin. long, broadly deltoid, 

 etjually sloping upwards and downwards from their apex. Leaves rudi- 

 mentary, minute, scale-like. Spines 1-1 J lin. long, in pairs, diverging, 

 grey, on narrow horny grey shields decurrent down both slopes of the 

 teeth, but scarcely beyond. Flowering-eyes about 2 lin. above the 

 spines, enclosed in the shields. Involucres (not seen) 3 together, about 

 2J lin. in diam., glabrous, with transversely ovate glands and fringed 

 lobes [Pax). — Pax in Engl. Jabrb. xxxiv. 72.

The above description, with tiie exception of tint of the involncres, is based 

 entirely npon Robeccbi-Hricchett', 287 ; tlie other nnnibers qnoted by Pax I have nob 

 seen. Tlie unniber 1061, howev.r, collected by Riva near the River Milmil, also 

 quoted by Pax nnilcr E. Rohecchii, l)elono^s to a })erfectly distinct species. Tiie 

 specimen seen of 1061 is very fragmenta y, consisting: of a section of an obtusely 

 5-an;;li'd stem 1^ in. in diam. and a loiigicudinal surface slice from a branch and 

 branchlet, which is scarcely or very obtusely angular, not obviously toothed, quite 

 spineless, with small shields about \ in. Xow^, shaped like tlie sole of a boot, enclosing 

 the tlowering-eye and not very horny ; the branchlet also is ascending, not at all 

 rccurveil. From this I suspect that two species have been included by Pax under 

 the name E. Rohecchii. 



IGO. E. Dawei, N.E.Br. "A small tree, usually palm-like 

 owing to loss of lower branches " [Bagshawe), 20-30 ft. liigh {Daive)^ 

 nearly leafless, spiny. Branchlets succulent, flat and thin in the 

 specimens seen, but stated by Dawe to be also 3-winged, constricted 

 into oblong or oblanceolate-oblong segments 4-8 in. long and 1 J-2J in. 

 broad or perhaps larger, very obtuse or slightly notched at the apex, 

 with the lateral branches usually narrowed to a short stalk-like base, 

 even or sinuate-tdothed at the margins, glabrous, apparently glaucous. 

 Leaves rudimentary or very small, recurving between the spines, 1 J-2 

 lin. long, elliptic or suborbicular, with the margins much recurved and 

 the upper side very convex, somewhat rigid, glabrous, soon deciduous. 

 Spines 1-2 lin. long, in pairs J-J in. apart, diverging, brown, becoming 

 blackish-brown and finally grey, on narrow horny shields, which are
