Calyx of five nearly equal and distinct herbaceous sepals, 

 quincuncially imbricated in aestivation, not produced or tu- 

 bular at the base, persistent. Petals 5, alternate with the 

 sepals, equal, usually obovate or obcordate, somewhat un- 

 guiculate, hypogynous, convolute, or frequently one petal 

 wholly exterior, or in the same plant occasionally quincun- 

 cially imbricated in aestivation, caducous. Hypogynous 

 GLANDS 5, alternate with the petals. Stamens 10, hypogy- 

 nous, inserted in two series on the short receptacle ; the five 

 exterior opposite the petals, and shorter than the five interior, 

 which are opposite the sepals and the glands : filaments all 

 antheriferous, subulate, flattened-dilated below, distinct to 

 the base, or usually somewhat monadclphous, persistent : an- 

 thers oblong, fixed by the middle, introrse, versatile ; two- 

 celled, destitute of any manifest connective, the cells opening 

 longitudinally. Pistil of five carpels (opposite the petals) 

 united to a prolonged and columnar central axis (gynophore) 

 which extends almost to the apex of the styles : ovaries 

 two-ovuled : styles distinct at the summit, their inner face 

 stigmatose. Ovules collateral and pendulous (always ?) from 

 about the middle of the inner angle of the cell, anatropous or 

 scmianatropous ; the raphe ventral ; the micropyle superior. 



Fruit of five membranaceous follicular carpels, with their
