13-2} in, long, #-2 lin. broad, linear or linear-lanceolate, acute and 
mucronate at the apex, shortly cuneate at the sessile or subsessile base, 
revolute at the margins, with a very prominent acute or almost wing- 
like keel beneath, glabrous on both sides. Cymes terminal, umbel-like, 
with 3 once-forked rays 4-1 in. long. Bracts under the involucres 
}-1 in. long, 2-4 lin. broad, ovate-lanceolate to subcordate-ovate, acute 
or acuminate and mucronate, rounded or abruptly contracted into a 
distinct broad petiole, otherwise as in the leaves. Involucre solitary, 
sessile, 2 lin. long, 24 lin. in diam., campanulate, glabrous outside and 
within, with 4 glands and 5 subquadrangular oblong or ovate toothed 
lobes; glands about 3 lin. in their greater diam., compressed-funnel- 
shaped when viewed from the back, shallowly concave and transversely 
oblong when viewed from above, entire. Capsule erect, 34-4 lin. in 
diam., glabrous ; styles 1} lin. long, united for 3 of their length, stiffly 
erect, narrowed at the apex into the minutely bifid stigmas. Seeds 
2-2} lin, long, ovoid, subacute, smooth, light ochreous-brown.

atuber, producing 1 or more annual stems 4~9 in. high, branching into 
4 3-rayed umbel at the top and with 1-2 pairs of opposite branches (or 
® whorl of them, Pax) below, glabrous. Leaves opposite, whorled at 
the base of the umbel, sessile, subcoriaceous, $-14 in. long, 2-7 lin. 
broad, with the basal pairs very much reduced or scale-like, lanceolate or 
elliptic, acute, rounded or narrowed at the base, glabrous on both sides. 
branches and rays of the umbel 2-24 in. long, once-forked, glabrous. 
Bracts 6-10 lin. long, 4-6 lin. broad, sessile, ovate, acute. Involucres 
solitary, sessile, 14-2 lin. in diam., glabrous (pubescent, Pax), with 4 
glands and 5 oblong truncate toothed lobes; glands ? lin. in their 
greater diam., transversely oblong, concave, entire. Ovary glabrous, 
exserted on a recurved pedicel ; styles 3 lin. long, free to the base, not 
Spreading, bifid at the apex. Capsule about 2 lin. in diam. and rather 
longer than broad, oblong, trigonous.

van” not seen the type of this species, but describe from Dekindt’s specimen, 
dea a named E. verticillata by Pax himself, and agrees with the original descrip- 
diag i erg the stem does not bear 2 whorls of branches and the involucres are 
in sabia ed by 4 bracts and are glabrous. The presence of 4 bracts surrounding 
Cinna? ucre in the type suggests that it is abnormal, as no Euphorbia I have 
mined has been found to have 4 bracts to the same involucre.
