ENUMERATION OF LEGUMINOS. 595 
and appears to me to be of no importance. Indeed, although 
I have cut across several pods, apparently fully formed, of 
E. Meyer’s A. gracilis, I have only once seen a slight inflexion 
inside, though, in general, the carinal suture is slightly de- 
pressed outside. .Leobordea of Delile, belongs in every re- 
spect to the same section as Capnitis, E. Mey., but the 
northern species added to it by Boissier, Fenzl and Ledebour, 
have a much more prominent lower tooth to the calyx, and 
belong to the section Leptis. 
Whilst writing out these observations for the press, I have 
received the April number of the Annales des Sciences Na- 
turelles, in which is a paper on the northern species, by 
Spach, where that writer places them in Leobordea, and 
suggests the junction, under that name, of some of the 
above-named Cape genera, This name of Leobordea is, it 
is true, the first that has been published as a substantive 
genus, but in a confined sense, without any reference to the 
South African species, which De Candolle had long pre- 
viously proposed as a distinct section, under the name of 
Lotononis, expressing at the same time his opinion that it 
would thereafter be necessary to consider this section as a 
distinct genus. As, moreover, De Candolle's Lotononis would 
include all the species I now propose to refer to it, which 
Delile's Leobordea would not, it may surely be considered 
that the priority of the former has been sufficiently esta- 
blished for its adoption as the generic name, especially as, 
having been taken up by Ecklon and Zeyher, it is already 
applied to a much greater number of species than Leobordea, 
Spach does not compare Delile’s genus with De Candolle's 
Lotononis, 
As a whole, the genus, as now proposed, comes yery near 
to Crotalaria on the one hand, and to Argyrolobium on the 
other, accompanied frequently by much of the habit, though 
none of the character, of Lotus. From Crotalaria, it is 
generally known by the form of the calyx, the blunt keel, and 
the pod more or less compressed when young. There are 
some species, however, where the calyx is not distinguishable
