more reniform, and more deeply cordate leaves, with shorter and 
more densely pilose petioles ; in its mode of inflorescence it 
resembles it, as well as C. andromorpha. Its internodes are 
3-3| inches long ; the leaves are 2^-2^ inches long, 2|-3 inches 
broad, with a somewhat acute basal sinus ^ inch deep, and a 
petiole 1^ inch long, inserted ^ line within the margin of the 
sinus. The raceme is 5^ inches long, with a slender and very 
woolly rachis, which is divided at intervals of ^ inch by axillets 
commencing at the ‘base, which are furnished with an acutely 
oval bract i line long, and three or four fasciculated cymules, 
each 3 or 4 lines long, with short dichotomous branches termi- 
nated by a subcapitate head of very minute flowers ; rarely a 
few of the more inferior axillets have a leaf-like bract 2 or 3 lines 
in diameter. The $ raceme is 3 inches long, on a slender rachis, 
with bracts ^ inch apart, 2 lines in diameter, diminishing up- 
wards. 
MM. St. Hilaire and Tulasne considered this species to be 
identical with C. mucronata of Richard, a plant widely diffused 
over Southern Africa ; but that will be found to be very 
different.

This species approaches C. Australis, St. Hilaire, but differs 
in its glabrous polished branches, its more peltate and more 
acute leaves, their shorter and subglabrous petiole, and in the 
form of its inflorescence. Although approaching C. littoralis in 
the style of its inflorescence, it is very dissimilar in other respects.
