putamen 1-3, 1-2-spermous. Seeds plano-convex smooth ; albumen 

 thin (or 0), more rarely rather thick ; cotyledons of erect somewhat 

 thick embryo rather fleshy. — Trees or shrubs, erect, sarmentose or 

 decumbent, often uncinate-aculeate ; leaves alternate, entire or 

 crenate, coriaceous or membranous, glabrous or tomentose, at base 

 oftener 3-5-nerved ; stipules 2 ; both spinescent straight or hooked ; 

 or one caducous ; flowers ^ in axillary short or subumbellate cymes.^ 

 {All warm regions.^) 



20. Condalia Cav.* — Flowers oftener hermaphrodite ; receptacle 

 broadly oboonical, lined with thick fleshy flat 5-gonal disk ; calyx 5- 

 phyllous, valvate, and other characters of Zisyphus. Petals 5, small 

 [Microrhamnus) or oftener 0. Germen immersed in concavity of disk 

 free ; style short thick, at apex stigmatose 2-3-lobed ; cell of germen 

 1 ; ovules in cell 2 subbasilar ascending ; mioropyle introrsely 

 inferior ; spurious septum more or less incomplete ventral somewhat 

 projecting between the two ovules. Fruit drupaceous or finally 

 sicoate, girt at base with cupule of receptacle; putamen thick osseous 

 or woody, 1- or spuriously 2-locular ; testa of seeds thin ; cotyledons 

 of sparsely albuminous, sometimes subruminate, embryo flat. — Eigid 

 ramose glabrous shrubs ; branches spinescent ; leaves ^ alternate or 

 fasciculate subsessile entire coriaceous penninerved, deciduous ; 

 stipules minute, deciduous ; flowers ® in axillary cymes, few or
