C. rHomBIFoLIA (Haworth, Phil. Mag. 1825, July, No. 327, p 388). 
Caulescens, foliis late obovato-spathulatis sesqui longioribus quam 
latis, glauco-viridibus i1mmaculatis vel maculis obscuris viridibus 
paucis preditis, facie superiore plano, inferiore paullulum convexo, 
racemis simplicibus vel furcatis, floribus solitariis vel deorsum 
geminatis sessilibus, calycibus corollis quintuplo brevioribus, corolle 
segmentis deltoideis roseis patulis tubo quintuplo brevioribus. — 
D.C. Prodr. loc. cit. C. hemispherica, Harv. Fl. Cap. i. p. 376, 
ex parte. 
A native of the Cape of Good Hope. 
General habit of the preceding; the stem the same colour; the 
deaves the same kind of glaucous-green, with a horny edge, but 
not at all spotted or only very faintly so, when old, with a few 
blotches of darker green, broader upwards, the broadest part 
fully three-quarters of the distance from the base to the apex, 
the apex more broadly rounded, the base also broader, and the 
upper face in the lower part flat; the raceme often, but not 
invariably, branched ; the flowers the same size and colour and 
arranged in the same way, but not at all stalked; the calyx 
shorter in proportion, and consequently more strictly campanu- 
late; the corolla-tube thicker and less graceful; the segments 
shorter in proportion, rather deltoid than lanceolate, and not 
decurved. ; 
This and the preceding may perhaps be two varieties of a 
single species, but assuredly they are radically different from 
C. hemispherica, with which Dr. Harvey has combined them. Of 
the true hemispherica a good figure will be found in DeCandolle’s 
‘Plantes Grasses,’ t. 87, so that we have not thought it worth 
while to reproduce it here. In this the leaves are barely an inch 
long, not at all spathulate, at least twice as thick as in our plants, 
consequently very much more convex on the back (whence the 
name), slightly convex on the face, in colour a pale apple-green, 
and marked with rows of distinctly visible minute papille, which 
these two do not exhibit.—J. G. B. 
This species requires much the same soil and treatment as 
C. maculata, just described. Mr. Thos. Cooper found it in South 
Y 
Africa, and I received my plants from him.—]JV’. W. S.
