known. However, neither has been taken up, as there are still older ones 
available. According to the Vienna rules, duplicate binomials are inadmissible, 
and hence, if Cajan be accepted as the generic name, Cajan cajan (L.) Millsp. 
is inadmissible and a new combination would be necessary; the oldest specific 
name in this case would be from Cytisus pseudo-cajan Jaeq. (1772). If, how- 
ever, Cajanus be retained as the generic name, the oldest specific name would 
of necessity have to be taken from Cyfisus cajan Linn., as the combination of 
the specific name cajan under the genus Cajanus hardly constitutes a duplicate 
binomial. Under present rules Cajan cajan is inadmissible, but Cajanus cajan 
is entirely proper and admissible (!), a very good illustration of inconsistency.

In regard to the specific name for this species, volubile, being by far the oldest 
is here adopted. Blanco’s description of Cytisus volubilis, although short, applies 
unmistakably to the material cited above. Prain™ has called attention to the 
fact that Atylosia mollis Benth. is a mixture of two different species, and the 
name, derived from Collaea mollis Grah., is applicable only to a Himalayan plant.
