I. OURATEiE. 



1. Ouratea Aubl. — Flowers hermaphrodite; receptacle convex. 

 Sepals 5, or more rarely 7, 8, very often coloured, imbricated, per- 

 sistent or deciduous. Petals 5, slightly longer than calyx, obovate, 

 shortly unguiculate, imbricated or contorted, usually deciduous. 

 Stamens 10, inserted with perianth, 2-seriate ; filaments free, very 

 short ; anthers elongated, outwardly rugose, 2-locular, poricidal at 

 apex. Carpels 5 (or more rarely 6-8), alternipetalous, inserted at 

 summit of receptacle, produced in cylinder beyond insertion of 

 androceum. Germen free, 1-locular; style more or less gynobasic, 

 afterwards strictly coalescing in long conical tube, at apex stigma- 

 tiferous, not thickened, free at a greater or less height, or not 

 distinct ; ovules in each germen solitary, ascending, subbasilar ; 

 micropyle extrorse, inferior. Drupes 5, or fewer by abortion, 

 inserted on variously enlarged coloured receptacle. Seed suberect ; 

 testa membranous ; embryo exalbuminous ; cotyledons plano- 

 convex, fleshy ; radicle short, inferior. — Glabrous trees or shrubs ; 

 leaves alternate, persistent, simple, coriaceous, nitid, sharply serrate; 

 nerves crowded, parallel; stipules 2, usually slightly super-axillary, 

 free or connate ; flowers in terminal or axillary racemes, sometimes 

 sub umbellate, compound cymiferous ; pedicels bracteolate, articulate 

 at base {All Trop. and Subtrop. regions). See p. 365. 



2. Elvasia DC — Flowers 3-6, or oftener 4, 5-merous; recep- 

 tacle depressed conical. Sepals petaloid and petals same in number, 

 alternate (of Ouratea or Ochna). Stamens hypogynous, 6-10, or qo ; 

 filaments inserted slightly above perianth, persistent ; anthers elon- 

 gated (Eaelvasia?) or short {Iloslmannict), poricidal at apex. Germen 

 placed at summit of slightly stipitiform receptacle, outwardly sul- 

 cate ; cells 2 {Hostmannia), or 4, 5 {Euelvasia), alternipetalous ; style
