10 MR. G. BENTHAM’S SYNOPSIS OF DALBERGIE E, 
Galegea and Phaseolee : the pedicels are usually clustered two or 
more together in the axil of the same bract ; when they are more 
than two, the axis of the cluster often forms a thickened gland-like 
node, or lengthens into the rachis of a very short lateral branch. 
The third subtribe, the Geoffroyea, is technically characterized 
by the fruit, which, in most cases, is a real drupe. It is said by 
some to be two-valved. In the few species in which I have seen 
it ripe (one Geoffroya, three Andiras, four species of Dipteryx, and 
two of Pterodon) the endocarp showed no more signs of splitting 
than do the stones of almonds or cherries in their ordinary state, 
but, like these, it is probable that the stones of the Geoffroyee may 
open in germination along the sutures;.a circumstance, which would 
not bring them under dehiscent fruits properly so-called. The 
sarcocarp in most Geoffroyee clings hard to the stone, and most 
probably rots away in germination, but in Pferodon it appears to 
fall off in two valves, leaving the flat and thin but woody putamen 
still adhering to the specimens, so as to have been occasionally 
described as the whole fruit. "When in flower, the G'eoffroyec, аз 
a whole, have little to distinguish them absolutely from other 
Dalbergiec, although each genus has characters of its own which 
may be traced in the flower as well as in the fruit. The foliage 
is variable, though always pinnate; the keel-petals free, or very 
slightly cohering at the top ; the staminal tube split open on the ` 
upper side, but never on the lower side; the ovary short, usually 
thick, with never more than four ovules, of which only one ripens 
into a pendulous seed, and in Dipteryx and Pterodon even the 
ovule is solitary. 
Before proceeding with the technical enumeration, I subjoin а 
few general observations on individual genera. 
DALBERGIA and EcASTAPHYLLUM. 
These two closely connected genera are readily distinguished 
by their anthers, which are not, as in all other Dalbergiea, versatile 
with parallel cells opening longitudinally, but small, erect, and 
didymous; their cells placed back to back, opening in diverging or 
divaricate slits, which are either so very short as to be reduced 
to oblong terminal pores, or are more or less continued to the 
base of the anther; in the former case the two cells are often quite 
distinct at the top, projecting considerably above the connectivum ; 
or when the cells open longitudinally they are usually contiguous 
at the apex, spreading widely at the base. In some semidiccious 
species the two forms of anthers are represented in the two sexes.
