 anthers basifixed, snbreniform or suboblong, 2-rimose at margin. 

 Staminodes in female flower 5- cc, sterile or sometimes furnished 

 with fertile anthers. Germen sessile ; styles 3-6, short or more or less 

 elongated, unequally dilated, stigmatiferous at apex ; placentas same 

 in number, parietal ; ovules on each co, anatropous. Berry large, 

 subcorticate ; seeds oo ; testa hard, striate ; albumen oily ; embryo 

 axile ; cotyledons foliaceous, flat or subplicate. — Trees ; leaves alter-

36. Rawsonia Harv. & Sond. 5 — Flowers polygamous ; sepals 4, 5, 



much imbricated, gradually proceeding to same number of petals, 



much imbricated. Scales complanate subpetaloid or shortly pilose 



(Basylepis 6 ), placed inwardly at the base, before each petal. Stamens 



co, inserted on slightly dilated receptacle ; 7 filaments linear or 



lanceolate-oblong, more or less sagittate at base. Germen superior; 

 placentas parietal, oo-ovulate ; style erect, stigmatiferous at apex with 

 more or less elongate lobes, 8 sometimes finally radiate (Euraivsonia).
