Calyx of five herbaceous entire sepals, quincuncially im- 

 bricated in sestivation, persistent. Petals 5, hypogynous, 

 their claws sometimes slightly united, obovate, convolute in 

 aestivation, caducous. Hypogynous glands 5, opposite the 

 sepals and next the base of the fertile filaments, or 10, the 

 additional ones opposite the sterile filaments. Stamens hy- 

 pogynous, monadelphous at the base : fertile filaments 5, 

 alternate with the petals, subulate or setaceous ; the sterile 

 alternate with these, reduced to subulate interposed teeth, or 

 often obsolete : anthers two-celled, introrse, the cells open- 

 ing longitudinally. Ovary globular, five-celled, the cells 

 opposite the petals, more or less vertically divided by an in- 

 troflexion of the dorsal suture which forms an imperfect 

 partition, sometimes becoming completely ten-celled in this 

 way : styles 5, distinct, or united at the base, occasionally 

 combined almost to the summit : stigmas terminal and capi- 

 tate, or more or less linear and introrse. Ovules a single 

 collateral pair, pendulous from the inner angle near the apex 

 of each cell, anatropous, the raphe ventral. 



Capsule scpticidal, separating into five incompletely two- 

 celled and two-seeded coriaceous cocci which become two-
