lobes of a thick disk ; filaments free ; anthers introrse ; connective

 capitate style with stigmatic apex ; cells 2, incomplete alterni- 

 petalous. Ovules in each cell 2, ascending ; micropyle extrorsely 

 inferior. Fruit capsular oblong, loculicidally 2-valvate, tardily 

 dehiscent. Seeds oblong, enclosed in membranous multifid aril ; J 

 albumen fleshy; cotyledons of straight embryo 2 oblong. — A glabrous 

 under-shrub ; leaves opposite, very shortly petiolate, minutely stipu- 

 late, entire or serrate ; flowers in axillary cymes. 3 (North-western 

 mountainous America?') 



3. Catha Foesk. 5 — Flowers nearly of Euonymus, 5-merous ; 

 receptacle shortly concave. Calyx short 5-lobed, imbricate. Petals 

 5, longer erect, imbricate, finally opening at apex. Stamens 5, alter- 

 nipetalous, exterior to cupular disk ; filaments subulate erect ; 

 anthers short sub-2-dymis, introrsely 2-rimose. Germen free, 3- 

 locular ; style short, apex shortly 3-lobed stigmatic ; ovules in cells 

 2, ascending; micropyle extrorsely inferior. Fruit capsular, linear- 

 oblong or subclavate, obtusely 3-gonal, loculicidally 3-valved; septa 

 thickened in the middle. Seeds 6 1-3, elongate, produced below to a 

 thin (arillate ?) membranous unequally 3-angular wing ; testa crusta- 

 ceous slightly punctulatc-rugose ; albumen fleshy ; cotyledons of 

 (green) axile embryo foliaceous elliptic ; radicle rather long inferior. 

 —A glabrous shrub ; leaves oftener opposite oblong-lanceolate coria- 

 ceous, serrate or subentire ; stipules minute ciliolate ; flowers in 

 axillary short dichotomous ramose cymes. [Arabia, warm Eastern 

 and Southern Africa. 7 )
