Stamens generally 3, more rarely 5, or 2, 4, 6, very rarely 7-15-20 

 {Asterandra,^ Plmostemon^ Oxalistylis^ Orlicularia,^ Williamia^ Chori- 

 Sandra^), central, inserted on rather convex receptacle; filaments free 

 or more or less high l-adelphous, equal or unequal I^Kirganelia''); 

 anthers 2-locular extrorse, longitudinally or horizontally rimose, much 

 varied in form, muticous or apiculate. Glands of disk equal in number 

 to and alternating with the sepals free or unequally or equally 1- 

 adelphous, in female flower sometimes connate in urceolate disk, 

 sometimes ((rfocAic^wra*). Germen sessile; cells usually 3, more 

 rarely 2 or 4, very rarely 5-15; style branches equal in number 

 to cells, entire or oftener 2-lobtilate or 2-fld stigmatiferous at apex. 

 Ovules in each cell 2, collateral, or descendent, more or less com- 

 pletely anatropous or peritropous, or more rarely suborthotropous 

 subadscendent ; micropyle extrorse superior. Fruit capsular ; exo- 

 carp sometimes subfleshy or fleshy often soluble ; cocci (usually 

 3) 2-valved, 1, 2-spermous. Seeds smooth verrucose or costulate; 

 external coat thin or more or less fleshy (arillate) ; outer coat 

 more or less thick, often crustaceous ; hilum subbasilar (in seeds 

 suborthotropous) or more or less high impressed, at internal angle 

 small or more or less depressed subregular, or more rarely very 

 unequal, irregular and concave ; micropyle not carlinculate ; cotyle- 

 dons of straight or arched copiously albuminous embryo rather wide 

 complanate. — Trees or oftener shrubs, undershrubs or herbs ; habit 

 much varied ; branches usually alternate, sometimes 2-morphous ; 

 twigs sometimes dadodiform subaphyllous {Xylophylla^), oftener 

 when leaves are evolved, simulating a compound pinnate leaf 

 and frequently (like the leaf) articulate at base, and finally solute from 

 branch ; leaves alternate or rarely opposite, often 2-stichous, some- 

 times reduced to squamules, shortly petiolate or sessile, 2-stipulate, 

 penninerved, often unequal at base ; flowers (small, often white or 

 purplish-virescent) in axils of leaves or sometimes bracts, solitary or
