The Abyssinian specimens are much more hirsute than the southern ones, but 
there appears to be no other difference, and this is only one of degree. 
* After drawing up the descriptions from De Candolle, L.c. I had an opportunity 
of seeing a set of Welwitsch’s specimens at the British Museum, and found it neces- 
sary to make some considerable alterations in the dimensions, etc.
