This plant is certainly allied to I. hedyantha E. Z. It agrees in being 
several-stemmed with 3—4 jugate leaves — the racemes on peduncles 
the calyx sharply 5-toothed and the pod straight. But in I. nairo- 
biensis the peduncle are shorter — the racemes shorter and fewer flowered 
— the flowers smaller and the pods shorter. 
I. hedyantha E. et Z. is a plant of the Mountains of the Eastern 
Frontern of South Africa. It also occurs in Nyasaland.

Dr. Hubert Winkler no. 3795! — Herb. Breslau, 
The flowers of this species in structure are allied to those of C. poly- 
sperma Kotschy. In both there are the two rather conspicuous bracteoles 
at the base of the calyx and in both the calyx lobes are long and the 
ovary linear. In C. Winkleri the standard is rather broader and not so 
densely pubescent externally and the carina has not such a long rostrum 
as in the figure of C. polysperma (Plantae Kotschyanae, tab. XIV).
