Calyx of five lanceolate or oblong sepals, valvate in aesti- 

 vation, rather coriaceous, deciduous. Petals 5, alternate 

 with the sepals, hypogynous, oblong-spatulate, quincuncially 

 imbricated, or convolute with one petal exterior, or some- 

 times with one wholly interior, in aestivation, deciduous. 

 Stamens indefinite, inserted on a short hypogynous torus : 

 filaments filiform, distinct or nearly so, or (in the American 

 species) collected into five phalanges and more or less united 

 at the base with each other and with a hypogynous petaloid 

 scale (staminodium), which stands before each petal and re- 

 sembles it, except in its smaller size : anthers fixed by the 

 middle, extrorse, two-celled ; the oblong cells separate, or 

 often disjoined by the forking of the filament, opening longi- 

 tudinally on the outside. Pollen smooth, simple. Ovary 

 ovoid, five-celled, the cells opposite the sepals : style colum- 

 nar, five-toothed at the dilated apex, the lobes introrsely stig- 

 matose. Ovules 2 in each cell, peritropous-ascending from 

 the middle of its inner angle, almost collateral, between am- 

 phitropous and anatropous, the micropyle centripetal-inferior.
