Stem slender, spreading, clothed with whitish mostly adpressed hairs. 
Leaves less than 6 lin. long, thick, oblong to oblong-lanceolate, base 
entire, truncate, nearly sessile, clothed with adpressed whitish hairs, 
sparsely above, densely beneath. Flowers solitary, on short slender 
peduncles 6 lin. long, bearinga pair of short linear tapering densely 
hairy bracts about 2 from the base. Sepals elliptic, obtuse, shortly 
cuspidate, silky, 3 lin. long. Corolla whitish, 7 lin. long, hairy in 
bud. Capsule not seen.—C. sagittatus, var. grandiflorus, subvar.

The specimen (which is a very meagre one) consists of a few slender shoots, 1-3 
in. long, springing from a sthall piece of woody stem, the upper part of which has 
been burnt. It suggests a new growth after a fire, and is probably not a fair 
representation of the plant. I cannot follow Hallier in regarding this as identical 
with the Abyssinian C. sagittatus, var. subcordata. Nor do I think, with the 
material at hand, that we are justified in regarding it as a form of C. sagittatus.
