Calyx of five (or rarely four) almost distinct sepals, im- 

 bricated in asstivation, persistent. Petals as many as the 

 sepals and alternate with them, somewhat perigynous, im- 

 bricated in aestivation, entire, very rarely retuse or obcordate, 

 sometimes obsolete. Stamens twice as many as the sepals 

 (very rarely fewer), inserted into a hypogynous or obscurely 

 perigynous more or less glandular-lobed disk : filaments fili- 

 form or subulate : anthers introrse, two-celled, the cells 

 opening longitudinally. Ovary one-celled : styles 3, one 

 opposite each of the two outermost sepals, the other alter- 

 nate with the third and fifth sepals, very rarely as many as 

 the sepals and opposite them, the inner face stigmatose. 

 Ovules indefinite, borne on a central columnar placenta, am- 

 phitropous. 



Capsule one-celled, chartaceous, dehiscent quite to the 

 base into as many quite entire valves as there are styles, 

 usually three, when they are as nearly as may be opposite the 

 three inner sepals ; rarely as many as the sepals, when they 

 are alternate with them. Seeds numerous, globose-reni- 

 form, campylotropous, not strophiolate, the crustaceous testa 

 smooth, granulated or muricate. Embryo coiled into a most-
