cotyledons of exalbuminous embryo thick suborbiculate or obcordate, 

 often auriculate at base ; radicle inferior short conical or lobed. — 

 Small shrubs, undershrubs, or oftencr herbs, sometimes viscous, 

 glandular pilose ; branches terete ; leaves opposite or verticillate, 

 sometimes alternate, entire penninerved ; flowers ' solitary or race- 

 mose; peduncle axillary, lateral or oftencr interpetiolate, 2 bracteolate. 3 

 {Both trop, and subtrop. Americas.*) 



10. Antherylium Rohr and Vahl. 5 — Flowers nearly of Grislea, 

 4-merous ; tube of receptacle obconical. Sepals 4, valvate; accessory 

 teeth 0. Petals 4, oblong, corrugately imbricate. Stamens 12-co , 

 inserted at margin of thin disk lining tube ; filaments free slender ; 

 anthers curved. Germen free at bottom of receptacle ; cells 4, com- 

 plete or incomplete above, oppositipetalous ; style slender flexuose, 

 at apex stigmatose truncate. Ovules in cells co , inserted on thick 

 placenta. Fruit capsular, at base stipate with calyx, large nozzled 

 above, membranous, sub-1-locular, septifragal ; seeds close minute. — 

 Glabrous trees or shrubs ; branches sometimes armed at nodes with 

 4 small spines ; leaves opposite or alternate petiolate entire ; flowers 

 axillary cymose, spuriously umbellate ; pedicels under flower 2-
