flowers^ in axillary and terminal very compound ramose many- 

 flowered cymes." [Trop, and subtrop, Oceania?^ 



12. Eerchemia Neck,* — Elowers 4, 5-merons, hermaphrodite or 

 polygamous ; receptacle concave hemispherical or turbinate, sometimes 

 cupular or subplane, lined with a disk. Germen free (immersed in 

 concavity of disk), 2-locular, attenuated to 2 -fid style ; branches at 

 stigmatose apex obtuse. Drupe ^ elongate-oblong obtuse, girt at base 

 with short cupule of receptacle ; putamen woody or crustaceous, 2- 

 locular. — Unarmed shrubs, erect or climbing ; leaves alternate pe- 

 tiolate, minutely stipulate, coriaceous penninerved ; nerves parallel 

 close; transverse veins slender; flowers^ disposed in the divaricate 

 twigs of a wide terminal ramosely- compound spike or of a much 

 branched raceme; solitary or cymulose, sessile or pedicellate.'^ 

 ( Warm regions of Africa and North America ^) 



13. Sageretia Ad. Be.^ — Flowers hermaphrodite (nearly of 

 Berchemia) ; receptacle hemispherical or urceolate. Disk lining tube 

 of receptacle, afterwards free and erect ; margin sub-entire or 5- 

 lobed. Germen immersed in concavity of disk free; cells 3; 

 1 -ovulate. Fruit drupaceous; pyrenae 3, coriaceous, indehiscent ; 

 seeds thinly albuminous and other characters of Scutia. — Unarmed or 

 spinescent shrubs ; leaves sub-opposite penninerved and reticulate 

 veined, entire or serrate ; stipules minute, deciduous ; flowers ^*' on 

 the opposite divaricate branches of a terminal or axillary oftener 



^ Ferruginous or sometimes white, pendent. * Purple or black. 



2 A genus from its germen mostly inferior ^ Greenish, or whitish, 



(within adnate to receptacle) and fruit cupulate ^ A genus hence allied to Colubrina, thence 



to middle, very closely allied to Colubrina, from to Zizyphics (n. 19). 



vhich it can scarcely be generically separated, ^ Spec. 8-10. Jacq. Ic. Rar. t. 336 {Rhamnus).
