 portions sometimes climbing, unbranched, with spreading rufescent 

 hairs, 1|-1 ft. long. Leaves thin, lanceolate, shortly petioled, f-lj in. 

 long, more or less hairy, with short adpressed reddish-brown hairs,

 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, bearing a pair of short linear tapering densely 

 hairy bracts about f- from the base. Sepals elliptic, obtuse, shortly

The specimen (which is a very meagre one) consists of a few slender shoots, 1—3 

 in. long, springing from a small 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.
