76 NATURAL HISTORY OF PLANTS. 



and stamens of Ehamnus. Germen free, immersed in disk ; cells 2, 

 1-ovulate. Fruit ovoid baccate (or sometimes drupaceous ?), apicu- 

 late to base of style and girt at base with cupular receptacle, finally 

 corticate subdry, indehiscent; endocarp membranous, 1-2-locular. 

 Albuminous seeds and other characters of Ehamnus. — Shrubs ; leaves 

 opposite or sub opposite entire, with very closely lineate nerves ; 

 stipules small, deciduous; flowers^ crowded in axillary subsimple 

 or fasciculate cymes.^ {Trop. and South America.^) 



3 ? Macrorhamnus H. Bn.* — Flowers hermaphrodite ; petals 5, 

 subfree (?). Petals and stamens... ? Germen free, 3-locular. 

 Fruit shortly ovoid drupaceous ; exocarp ^ separable ; lobes 3, at apex 

 2-fid ; endocarp woody 3 -coccous ; cocci separable, parting elastic- 

 ally inwards. Seeds in cocci solitary suberect exarillate obovate 

 much compressed ; testa crustaceous nitid ; exalbuminous embryo

 nodose at leaves ; leaves subopposite or alternate ovate penninerved, 

 at base, sub- 5-7 -nerved reticulate-veined; flowers axillary solitary!?) ; 

 fructiferous peduncles curved.^ [Madagascar J) 



4. Karwinskia Zucc.^ — Flowers of Rhamnidium ; germen free, 

 immersed in disk ; cells 2,3, incomplete ; ovules in each 2, ascending. 

 Fruit of Rhamnidium (glandulous) ; putamen 1, 2-locular. Seeds 

 in cells solitary obovoid ; testa verrucose (dark coloured) ; albumen 

 thin; cotyledons of erect embryo ovate fleshy. — Shrubs; leaves 

 opposite or subopposite oblong penninerved punctulate; stipules 

 membranous, deciduous ; flowers in axillary cymes, oftener pedun- 

 culate in pairs. ^ [Noi^th and West South America}^)
