Calyx of 6 thin and membranaceous roundish-oval sepals, 

 imbricated in two series in aestivation, caducous when the 

 corolla opens. Petals 6, alternatively imbricated in aestiva- 

 tion, hypogynous, consimilar, larger than the sepals, round- 

 ish-obovate, sessile, not glandular, plane, spreading, early 

 deciduous. Stamens 6, hypogynous, opposite the sepals, 

 shorter than they: anthers oblong, longer than the terete 

 filament ; the cells somewhat extrorsely adnate to the con- 

 nective, their face (except an inner margin) separating in 

 dehiscence as an uplifted valve. Ovary oblong-ovoid, one- 

 celled, nearly straight : style very short : stigma terminal, 

 circular, depressed, slightly grooved across the middle. 

 Ovules 5 or 6, borne in two series near the base of the pla- 

 cental line which marks the inner side of the cell, ascend- 

 ing, globular, anatropous. 



Berry globular, somewhat gibbous, apiculate with the 

 nearly sessile stigma, unilaterally 2 - 4-seeded ; the flesh thin. 

 Seeds 2 to 4, ascending from near the base of the cell on 

 the ventral side, oblong, gibbous, slightly curved ; the testa 

 fleshy-coriaceous. Albumen fleshy, or corneous when dried. 

 Emrryo in the axis of the albumen, extending from the base 

 nearly to the middle, slightly curved to correspond with the 

 curvature of the seed: radicle inferior, slender ; the coty- 

 ledons nearly of its length, oblong, pretty thin, parallel with 

 the raphe.
