Calyx of 5 sepals ; the two exterior minute and resem- 

 bling bractlets; the three others ovate, equal, convolute in 

 aestivation, colored (yellowish) inside, united at the base, 

 persistent, at length connivent in a tube and inclosing the 

 capsule. Petals 5, hypogynous, convolute in aestivation, 

 obovate or cuneiform, much larger than the sepals, thin and 

 delicate, caducous. Stamens 9 to 30, hypogynous, decidu- 

 ous : filaments filiform : anthers roundish, innate or slight- 

 ly introrse, the cells opening laterally by a longitudinal line. 

 OvABT'sessile on the convex torus, ovoid, strictly one-celled, 

 with three nerviform parietal placentas : style long and fili- 

 form, straight, persistent : stigma truncate, minutely three- 

 lobed. Ovules two from the lower part of each placenta, 

 orthotropous, ascending, on slender funiculi. 



Capsule oblong, somewhat triangular, inclosed in the 

 connivent calyx, one-celled, three-valved ; the chartaceous 

 valves bearing the narrow placentae upon their middle. 

 Seeds one or two on each placenta, ascending from near 

 the base, ovate ; the testa nearly smooth, crustaceous. Em-
