I have not seen female flowers of typical EH. media, but the male plant seems 
identical with that used asa source of rubber in Natal, which is probably E. Tirueallt, 
Linn. But flowers of the Indian plant have not yet been seen. 
1l5a. Euphorbia darbandensis, .V./. Br. A succulent branch- 
ing spiny “ cactus-like” plant 6-18 in. high (Chevalier), subdicecious ; 
branches cylindric, 1-14 in. thick, spiny and apparently somewhat tuber- 
culate at the apical part, spineless and apparently without tubercles 
below; glabrous. Leaves broken, only basal portions 2-3 in. long and 
about 4 in. broad seen, linear, narrowing at the base into an acutely 
triangular petiole and with a wing-like keel 2 lin. broad along the midrib 
beneath, glabrous, soon deciduous. Spines rather crowded, but confined 
to the terminal 1-24 in. of the branches, evidently deciduous, leaving 
the stem naked below, 4-7 lin. long, dilated and flattened from above 
at the base, where they end abruptly and do not dilate into a horny 
shield, dark brown. Peduncles solitary in the axils of the leaf-scars at 
the tips of the branches, 6-7 lin. long, bearing 3 involucres in the male 
or submoneecious plant and 1 in the female, glabrous. Bracts scale-like, 
submembranous, 14-12 lin. long, broadly ovate, usually torn at the 
rounded apex, glabrous. Involucres 13-2 lin. in diam., probably larger 
when alive, somewhat obconic or subcylindric-campanulate, scaberulous 
with very minute papille, with 5 glands and 5 subquadrate or trans- 
versely subrectangular toothed lobes; glands 1-1} lin. in their greater 
diam., transversely oblong, entire, with the inner margin slightly raised, 
apparently yellow. Ovary subacutely 3-angled, glabrous, exserted on
