38 NATURAL HISTORY OF PLANTS. 



micropyle of subbasilar ovule inferior, extroso or finally lateral. Eruit 

 dry, 1-2-pyrenous. Seeds in pyrense solitary exarillate ; cotyledons 

 of slightly albuminous embryo foliaccous. — Glabrous rigid shrubs ; 

 leaves alternate entire coriaceous (oblong ovate or sputliulate) cxstipu- 

 late ; flowers^ axillary, solitary or oftener cymose or glomerulate. 

 {Antilles^ New Mexico^ Texas?) 



17 ? Wimmeria Schltl.^ — Flowers nearly of Celastrus^ 5- 

 merous ; anthers oblong introrse, 2-rimose. Germen pyramidally 

 3-gonal, confluent at base with thick disk, attenuated to 3-lobed 

 style dilate stigmatic at apex. Ovules in cells go , inserted in 

 2-series in the internal angle. Fruit broadly oblong 3-alatc, cordate 

 at base, indehiscent ; wings broad membranous ; cell 1, l'-2-spermous. 

 Seeds terete narrow linear; albumen fleshy; cotyledons of axile 

 embryo flat oblong-lanceolate. — Small glabrous trees ; leaves alternate 

 petiolate exstipulate serrate coriacious ; flowers in axillary cymes. ^

18. Polycardia J^. — 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 go , 2-seriate 

 ascending ; micropyle extrorsely inferior. Capsule ovoid, loculicid- 

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

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

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

 ceous ; flowers few glomerulate, inserted either in the middle of the 

 upper surface of the costa, or in the emarginate apex of the obcordate 

 limb."^ {Madagascar,^)
