81 NATURAL HISTORY OF PLANTS. 



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

 thiu (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 l in axillary short or subumbellate cymes. 2 

 (All tv arm regions?) 



20. Condalia Cav. 4 — Flowers oftener hermaphrodite ; receptacle 

 broadly obconical, lined with thick fleshy flat 5-goual disk ; calyx 5- 

 phyllous, valvate, and other characters of Zizyphus. 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 ; micropyle introrsely 

 inferior ; spurious septum more or less incomplete ventral somewhat 

 projecting between the two ovules. Fruit drupaceous or finally 

 siccate, 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. — Rigid 

 ramose glabrous shrubs ; branches spinescent ; leaves 5 alternate or 

 fasciculate subsessile entire coriaceous pennincrved, deciduous ; 

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

 solitary. (Trop, and temp, regions of both Americas?)
