Calyx naked (destitute of an involucel), persistent ; the 

 five sepals united at the base, valvate in asstivation. Petals 

 5, obovate or obcordate, convolute in asstivation, hypogynous, 

 their claws adnate to the base of the stamineal column. 

 Stamens monadelphous in a column which gives oif about 

 the middle or near the apex a series of five broad and mem- 

 branaceous phalanges, situated opposite the petals (convolute 

 in aestivation), each bearing from four to eight anthers on 

 very short filaments, and at the summit divides into an inner 

 set of about ten narrow and usually diantheriferous phalan- 

 ges, or into about twenty filaments, most of which are united 

 below in pairs : anthers one-celled, as in the order. Ovaries 

 5 to 9, united in a circle around a central receptacle : styles 

 as many as the ovaries, united below, filiform, stigmatose the 

 whole length of the inner face. Ovule solitary in each car- 

 pel, peritropous-ascending, the micropyle inferior. 



Fruit of five to nine membranaceous reniform carpels, 

 which are muticous, or apiculate with a short soft beak, one- 

 seeded, separating from the central receptacle when ripe,
