38 NATDRAL HISTORY OF PLANTS. 



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

 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 spathulate) exstipa- 

 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 co , inserted in 

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

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

 Seeds terete narrow linear; albumen fleshy j 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-looular; style 

 short, apex shortly lobed stigmatic ; ovules in cells co , 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-
