genera, so natural, and at the same time so small a 
group. 
As a whole, the Rafnie may be at once known among 
simple-leaved Genistee by their smooth surface, without any 
hairs in any part of the plant, often more or less glaucous, 
and turning black when dry, by their leaves not many-nerved 
from the base, as in Borbonia, and by the inflorescence which 
is never racemose as is Crotalaria; but the peduncles (except 
in the very few cases where they are simple and one-flowered) 
are more or less regularly dichotomous, with foliaceous 
bractez frequently opposite at their ramifications. In cha- 
racters derived from the flower, Rafnia comes nearest to 
Crotalaria ; but the pod is very different.
