Erecfc shrubs or trees, rarely herbs. Leave's simple, abruptly 

 pinnate. Flowers usually large and sliowy, in axillary racemes and 

 terminal panicles. Calyx-t\ihe very short ; sepals broad or narrow, 

 imbricated. Petals 5, imbricated, subequal, usually broad. Stamens 

 normally 10, but rarely all perfect, 8-5 being often reduced to stamino- 

 dia or altogether absent ; anthers mostly but not invariably basitixed, 

 dehiscing by terminal pores or with the slit more or less continued lon- 

 gitudinally. Ovary sessile or stalked, many-ovuled ; style incurved, 

 stigma terminal. Fod very variable, terete or flat, usually septate, the 

 albuminous seeds flattened, sometimes parallel with the valves, some- 

 times with the septa, dry, dehiscent or indehiscent. Species 340, spread 

 everywhere in the tropics, a few extia-tropical.
