 ing, with 5 angles, 5 plaits, and 5 shallow, pointed, equal lobes. 

 Stamens (fig. 1.) 5, equal, awl-shaped, as long as the tube, to which 

 they are united for about half their length. Anthers heart-shaped- 

 oblong, upright, compressed, blunt. Germen egg-shaped, 4-celled. 

 Style (fig. 2.) central, thread-shaped, straight, upright, the length 

 of the stamens. Stigma thick, blunt, of 2 oblique lobes, united 

 above. Capsule (fig. 3.) nearly egg-shaped, often prickly, stand- 

 ing upon the permanent base of the calyx, of 2 half divided cells, 

 and 4 valves ; receptacles (placentae) 2 to each cell, columnar, ver- 

 tical, spongy, dotted, each attached, by a lateral process, to the 

 principal transverse partition or dissepiment. Seeds numerous, 

 kidney-shaped, dotted, covering the placentae. 



Distinguished from other genera, with a monopetalous, inferior
