590 LEGUMINOSÆ INDIGENOUS TO 
two in the majority of species, four, six, or eight in others, and in 
A. filicaulis (referred to Paraspalathus) above twenty. 
Pachyraphea contains but two species distinguished by the 
short, thick pod, which, however, passes gradually into the longer 
one of others of my Pachycarpe. The other characters given 
are either imaginary, or common to species referred to other 
genera. 
Cyphocalyz is established for the A. arida (one of my Carnosa), 
in which the two upper secondary nerves of the calyx are united 
in a thickish, somewhat fleshy, dorsal rib. But this is more or 
less the case in most of my Carnose, without ceasing decidedly 
with any particular species. Moreover, if the group were really 
to be considered as a distinct genus, there are already two older 
names published for it :—Sarcophyllum of Thunberg, and Sarco- 
calyx of Vogel. 
Plagiostigma, consisting of the single A. pinea, is so near to 
the two species referred to Pachyraphea, that the differences can- 
not be considered as of more than specific importance. 
Streptosema, with only two or rather three species, is charac- 
terized by the form of the keel and pods, which are, however,’ 
common to others not included ; by the very oblique stigmatic sur- 
face which exists in one only of two species, so much alike in 
every other respect, as to be usually considered as mere varieties, 
and by a supposed resupination of the flower which I cannot see 
in these or any other Aspalathi. 
Psilolepus contains two or three of my Pedunculares, which 
have certainly a peculiar habit, but unfortunately no common 
characters of any importance. The peculiar extra-axillary inflo- 
rescence relied upon, is owing to an irregular developement of the 
flowering branches, and not constant even upon the same indi- 
vidual, the long stipes of the pod exists only in one of the species, 
and if considered sufficient to establish a genus, Desvaux’s name 
of Acropodium should be adopted, and the other characters are 
common to several other groups. 
In Trineuria, Presl has nearly hit upon a very distinct group 
which alone might claim to be of generic importance, were the
