Euphorbia. | CXXI, EUPHORBIACEE (BROWN). 567 
long, oblong, toothed or lobed at the subtruncate apex. Involucres 
14-14 lin. in diam., with the central one shortly pedunculate, broadly 
obeonic or funnel-shaped, and the lateral pair subsessile between their 
bracts, and more cup-shaped, glabrous, with 4-5 glands and 4-5 broadly 
cuneate fringed lobes; glands 3-3? lin. in their greater diam., trans- 
versely oblong, entire, contiguous or perhaps sometimes more or less 
united. Ovary (young) not exserted, glabrous; styles 3 lin. long, 
shortly united at the base, entire and not thickened at the apex.

The only specimen seen consists of 4 pieces of stem 3—4 in. long, apparently split 
down the middie, which are mixed with aspecimen of Z. taitensis, Pax, in the British 
Museum, but have evidently got misplaced, as other sets of Kiissner’s do not contain 
this species mixed with EZ. taitensis. It is closely allied to #. glochidiata, Pax, but 
differs in having pedunculate cymes and the stem-angles produced into spine-like 
tubercles which are fleshy with horny margins at the basal 4, whilst in Z. glochidiata 
the slender forked spine arises direct from the toothless angle. 
124. E, uhligiana, Pax in Engl. Jahrb. xiiii. 86. A dwarf leafless 
spiny succulent, apparently about 4-8 in. high, branching into several 
simple or branched stems }-} in. thick when dried, interruptedly 4- 
angled, with the angles formed of very prominent compressed acute 
teeth with narrow horny grey margins (shields) more or less prolonged 
into a sort of neck supporting the spines and decurrent 4-3 of the way 
down to the tooth below. Leaves minute, rudimentary, scale-like. 
Spiues 3-6 lin. long, diverging, grey, witha pair of prickles }-2 lin. long 
at the base of the tooth. Involucres 1-3 together (really in 3-flowered 
cymes), sessile in the axils of the teeth, 14 lin. in diam., cup-shaped, 
glabrous, with the erect (?spreading when alive) rim divided into 5-7 
lobes (glands) by cut-like notches. Ovary and young capsule subsessile, 
not wholly exserted, glabrous ; styles 3 lin. long, slender, free nearly to 
the base, recurved, shortly 2-lobed at the apex.

Very closely allied to E. Schinzii, Pax, but the spines and horny margins of the 
teeti are grey (brown on Scoft-Elliot’s specimen, which otherwise seems to be this 
Species) and the apex of the teeth is much more acute and more prolonged than in 
&. Schinzii. This species, by the short union of the basal part of the two spines 
into one, forms a distinct connecting-link between the single-spined species, such as 
E. triaculeata and E. monacantha, by means of E. furcata and E. schizacantha on 
the one hand and the large series of distinctly 2-spined species on the other hand. 
_125. E. Schinzii, Pax in Bull. Herb. Boiss, vi. 739. A dwarf 
Spiny leafless succulent. Stems 4-8 in. high, simple or much-branched, 
4-angled, 4-5 lin. square, slightly channelled down the sides, with the 
‘pposing angles constricted so as to form opposite teeth or lobes }-j in. 
apart, with their upper slope nearly truncate and that below the spines 
gradual, margined by the narrow horny brown shields, which are 
not produced beyond the fleshy apex of the tooth into a sort of neck
