570 CXXII. EUPHORBIACEE (BROWN). | Euphorbia, 
eyes at the apex of the branches close to the spine-shields, lower 
down at 2-3 lin. above them. Cymes sessile, with 3 involucres, 2 of 
them on lateral peduncle-like branches }-1 lin. long, Bracts small, 
membranous, oblong, acute or toothed at the apex. Involucre 14-1} lin. 
in diam., cup-shaped, with a rim-like mark around the middle when 
hermaphrodite, glabrous, with 5 glands and 5 quadrate fringed lobes; 
glands 3-1 lin. in their greater diam., transversely linear-oblong, erect 
and closely contiguous in fruit, probably spreading in flower. Capsule 
immature, 1% lin. in diam., glabrous, with a slight rim-like calyx at its 
base, erect on a pedicel shorter than the involucre; styles 3 lin. long, 
united at the base, then recurved and curled like a cork-screw, slender, 
thickened at the apex.

Rootstock a tuber, sometimes several inches in diam. Stems numerous, 
erect, 2-3 in. high, slender, 2-24 lin. in diam., 3-angled, glabrous, 
yellowish-green ; angles acute, more or Jess sinuate-toothed. Leaves very 
rudimentary, scale-like, about 4 lin. long and 4 lin. broad, broadly 
deltoid. Spines 1-2 lin. long, in pairs 4-6 lin. apart, widely diverging 
and dilated at the base so as to form horny shields not longer than 
their breadth at the base, and bearing on the upper margin a seMml- 
circular leaf-scar. Flowering-eyes in the axil of and closely contiguous 
to the spine-shields. Cymes with peduncles 3-5 lin. long, at first with 
1 sessile male involucre, ultimately developing into a simple 2-branched 
cyme, with fertile involucres on branches 4-4 in.long, glabrous. Bracts 
3-14 lin. long, with the lower rounded and the upper obovate, very 
obtuse or rounded at the apex, apiculate, denticulate. Involucres phar

seen), cup-shaped, glabrous, yellowish, with 5 glands and 5 rather nae 
erect transversely oblong fringe-toothed lobes; glands contiguous, a i
