26 МЕ. Ө. BENTHAM’S SYNOPSIS OF DALBERGIE XE, 
former, almost; petaloid in the latter; and more especially in the 
pod, which in Dipteryz is а thick (although slightly compressed) 
drupe, with a tough, filamentous, somewhat fleshy, thick sarcocarp 
adhering closely to the hard, woody endocarp; whilst in Pterodon 
it is very flat, the sarcocarp very thin, and falls off in two valves, 
leaving a hard, flat, woody endocarp replete with reservoirs of oil. 
As, however, none of these differences are structural, but all re- 
ducible to degree in consistence and relative thickness, it is not 
impossible that intermediate species may hereafter be found re- 
quiring their reunion into one genus. 
I have followed the generality of botanists in considering Aublet’s 
two genera, Cowmarouna and Taralea, as sections only, retaining 
Schreber’s name for the united genus, as it would now be incon- 
venient to revert to either of Aublet’s; although I think that 
Cowmarouna, derived from a not uncommon local name of the 
Tonga bean, would not have been objectionable for the whole of 
the species. І have not, however, been able to take the opposite 
or alternate leaves for the sectional character, for that would 
have separated the D. nudipes from the D. oppositifolia ; but have 
derived the distinctions rather from the ovary, as being more in 
accordance with general habit. 
I now proceed to the technical synopsis of the genera and 
species.
