18. Polycardia J 6 . — Flowers nearly of Celastrus, 5-merous; 

 receptacle shortly cupular. Sepals 5, imbricate, and petals same in 

 number longer, contorted, open. Stamens 5, exterior to thick disk 

 adnate to receptacle ; filaments subulate ; anthers short introrse, 

 2-rimose. Germen half immersed in receptacle, 3-5-locular ; style 

 short, apex shortly lobed stigmatic ; ovules in cells œ , 2-seriate 

 ascending ; micropyle extrorsely inferior. Capsule ovoid, loculicid- 

 ally 3-5-valved; septa seminiferous within. Seeds co, ascending 

 elongate and girt at base with a deeply laciniate aril ; embryo . . . ? — 

 Shrubs ; leaves alternate articulate, entire or spinose dentate coria-
