imbricate, deciduous. PETALS 5, inserted on the receptacle, usually erect, claws 

 connivent or sometimes coherent, aestivation imbricate, deciduous. STAMEKS 5, 

 alternating with the petals ; filaments filiform or subulate ; anthers introrse, cells 

 opening by short or long longitudinal slits. OVARY free, sessile or stipitate, of 2 

 perfect cells, or incompletely 2-5-celled ; style terminal, simple ; stigma obtuse or 

 capitate ; ovules 2-seriate, horizontal or sub-ascending, anatropous. FRUIT a capsule 

 with 2-5 half-septiferous valves, or a more or less fleshy indehiscent berry. SEEDS 

 often few from arrest, often immersed in a pulp or viscous juice ; testa loose, raphe 

 short, thick. EMBRYO minute, at the base of a fleshy dense copious albumen ; 

 cotyledons indistinct.

Kttosporea; are connected -with Celastrinca: by the polypetalous isostemonous corolla, imbricate 

 .estivation, ascending anatropous ovules, dry or fleshy fruit, albuminous embryo, woody stem, and alternate 

 leaves. But in Celastrinea; the stamens and petals are inserted outside a fleshy disk lining the bottom of 

 the calyx ; the cells of the ovary are perfect ; the seeds are enveloped in a pulpy aril, and the embryo is 

 jixile in the albumen. There is also a real affinity between Pitfnspurctr and tin- polypHalous pentandrou-s 

 Kriotnea (Lcdinn), founded on the insertion, tho estivation and isostemony of the corolla, the many- 

 celled ovary, the simple style, the anatropous ovules, Ihe structure of the fruit, the albuminous embryo,
