RHAMN ACEM. 79 



(of Rhamnus). Fruit subglobular (of Noltia) ; cocci finally solute 

 and dehiscing within; seedsi compressed sparsely albuminous. — 

 Erect or sarmentose shrubs ; leaves alternate (or very rarely opposite) 

 petiolate, penninerved or 3-nerved at base ; stipules deciduous ; 

 flowers 2 in more or less ramose axillary cymes. {All trop, regions?) 



10 ? Cormonema Eeiss. 4 — Flowers nearly of Colubrina, 5-merous; 

 germon immersed in and free from disk, 3-locular. Fruit and other 

 characters of Colubrina; cocci of endocarp finally dehiscing witliin. 

 — Prickly trees or shrubs ; leaves alternate petiolate entire mem- 

 branous penninerved ; limb 2-glandulous at base ; stipules small 

 deciduous; flowers 5 axillary cymose. 6 (BrasiU) 



11 ? Alphitonia Reiss. s — Flowers hermaphrodite or polygamo- 

 dicecious (nearly of Colubrina) ; receptacle obconical and lined with a 

 thick, 5-gonal, often pilose disk. Stamens 5, involved with elongate 

 petals. Germen adnate at base to receptacle (hence also to disk) 

 attenuated in a 2-3-fid style to free apex. Cells and ovules of 

 germen 2, 3 (of Rhamnus): Fruit globular, ovoid or ovoid-conical, 

 clothed below the middle with cupule of receptacle ; exocarp either 

 thin, dry, or oftener Anally suberose-subcarnose and at maturity 

 pulverulent ; cocci woody 2, 3, separable, dehiscing longitudinally 

 within and at base free from seminiferous receptacle. Seeds 2, 3, 

 persistent after the fall of the cocci erect, exarillate or clothed from 

 base to middle with a loose obconical aril, pervious at apex ; testa 

 hard nitid ; 6 embryo albuminous.— Trees or shrubs, either glabrous, 

 or often ferruginous-tomentose ; leaves alternate petiolate entire 

 penninerved, oftener hoary beneath; stipules small, deciduous;
