Herbs. Leaves simple, often fleshy, usually opposite or whorled : stipules 

 or scarious. Flowers usually in cymes or clusters, rarely solitary, regular, ier- 

 maphrodite rarely polygamous. CtAyx of 4r-5 segments, united into a tube or 

 nearly distinct, free from the ovary in the Indian genera, often persistent Pe- 

 tals usually wanting, when present small. Stamens perigynous or hypogynous, 

 definite or indefinite ; staminodes sometimes present. Ovary free (except in 

 Mesembryanthemuni), 2-5-celled, syncarpous (except in Crisekia) ; styles as many 

 as the carpels ; ovules many in each carpel and axile, or solitary basal. Fntk 

 usually capsular, splitting dorsaJly or circumsciss, more rarely the carpels sepa- 

 rate into cocci. Seeds many or 1 in each carpel, xisually remform, compressed ; 

 embryo ciirved or ammlar, surrounding the farinaceous albumen, radicle next the 

 hilum. — ^DiSTBTB. Species 450, chiefly African, a few are scattered through most
