1. Oroxylum, Vent. 
A glabrous tree. Leaves opposite, large, 2-3-pinnate ; leaflets entire.

Dish large, cushion-like. Ovary sub-sessile, contracted at the base, 
compressed ; style slender ; stigma 2-lobed ; ovules in 4 vertical rows 
on each placenta, very many. Capsule very large, broadly linear, 
compressed parallel to the septum, septifragally 2-valved. Seeds very

joints ; primary pinnae about 45 pairs, the lower ones 2-pinnate at base, 
pinnules 3- to 5-foliolate ; leaflets ovate, entire, acuminate at apex, side 
ones rounded and often unequal at base, terminal one cuneate at base ; 
3 to 6 in. long, 2 to 2'5 in. broad ; main-nerves 4 to 5 pairs ; petiolules 
slender, -2 to - 3 in. long. Raceme branch-like, 2 to 3 feet long, very thick, 
lower part prominently marked with the ovate scars of fallen pedicels ;
