Stems shrubby, erect, attaining a height of three or four feet, 
simple or sparingly branched, round, an inch thick, laxly leafy 
towards the apex. Podaria rhomboid, spirally seriate, an inch 
deep, glaucous when young. Leaves subsessile, oblanceolate, 
herbaceous, four to six inches long by twelve to fifteen lines 
broad three-quarters of the way up, narrowed gradually from 
half-way down to the base, blunt or subacute, pale green, both 
sides quite glabrous. Heads several in a lax corymb on erecto- 
patent peduncles which exceed the leaves and are persistent, but 
fragile on the old stems. Pedicels single-headed, the floral leaves 
two or three, if the latter, broadly imbricated, broad-ovate, acute, 
spreading, rather fleshy, glabrous or finely downy. Involucre 
campanulate, glabrous or finely downy, the glands bright yellow, 
suborbicular, entire. Bracts and filaments hairy. Capsule quite 
smooth and glabrous, the styles connate at the base.

The seeds of this peculiar Huphorbia, which has but little 
beauty to recommend it, I received from Mr. T. Cooper, and 
were gathered in South Africa. It grows without difficulty in a 
cool greenhouse, potted in light sandy loam, and should have but 
little water during the winter.—W. W. S.
