A native of the cape of Good Hope; not uncommon.

naked, often rooting. Leaves opposite, the lower ones often with 
tufts of small leaves in their axils, sessile, an inch long, fleshy 
but firm, a line broad, naked, bright green, slightly channelled on 
the face, semicircular on the back, the lower nodes about half an 
inch apart. Flowers terminal, solitary, or more usually in pairs 
or several, and, if so, subpaniculate, the central one sessile and 
the lateral ones stalked. ully-expanded flowers five-eighths to 
three-fourths of an inch broad, with two green lanceolate bracts 
close to them on the outside and exceeding them, the divisions of 
the single floral envelope ovate-lanceolate, white within, three or 
four lines deep, green and adpressed-hairy on the outside, but 
becoming white towards the edges. Stamens more than twenty, 
about half as long as the calyx. Capsule depresso-globose, 
obscurely pentagonal.—J. G. B. 
Seeds of this plant were sent to me from the Cape of Good 
Hope by Mr. Thos. Cooper. It grows well in any hght garden 
soil, and requires a cool greenhouse treatment.—W. W. S.
