dinally. Seeds smooth ; testa crustaceous, arillate to hilum ; coty- 

 ledons of albuminous embryo elliptical or obovate. — Small trees or 

 shrubs, sometimes spinescent ; leaves opposite or generally alter- 

 nate, entire or dentate, penninerved or 3-plinerved at base, glabrous 

 or somewhat scaly or canescent tomentose beneath, petiolate ; 

 stipules small, caducous ; flowers 1 in corymbs or racemes terminal and 

 axillary to uppermost leaves of twigs, densely ramose, cymiferous or 

 glomeruliferous, umbellifurm or elongate thyrsoid. (Temp, and trop, 

 west, regions of both Americas}) 



16. Ventilago G^irtn. 3 — Flowers hermaphrodite or more rarely 

 polygamous ; receptacle shortly obconical or broadly cupular, lined 

 with a thick annular or obtusely 5-gonal disk flat or depressed above. 

 Sepals 5, valvate, carinate within. Petals same in number deflexed 

 cucullate, entire or 2-lobed at apex. Stamens equal in number; 

 filaments free or adnate to petals at base ; anthers introrse or laterally 

 riniose ; connective sometimes excurrent. Germen immersed in 

 centre of disk, 2-locular; style very short compressed, stigmatose at 

 apex, shortly or very shortly 2-lobed, afterwards accrescent. Fruit 

 dry, indéhiscent, subglobular, girt at the base or to a greater or less 

 height with the cupular receptacle apiculate to style accrescent and 

 dilated on both sides to an erect linear membranous or coriaceous 

 veined wing. Seed 1, exalbuminous ; cotyledons of fleshy embryo 

 thick ; radicle inferior short. — Scandent or sometimes subprostrate 

 shrubs, glabrous or pubescent; leaves alternate ovate or oblong, 

 oftener oblique at base, petiolate ; stipules minute, caducous ; flowers 

 in terminal or axillary more or less compound ramose cymiferous 

 racemes, bracteolate. ( Warm Asia, Africa and Oceania})
