Calyx of four herbaceous concave sepals, imbricated in 

 asstivation, deciduous ; the two exterior lateral, rounded, 

 much shorter than the anterior and posterior. Petals 4, un- 

 equal, alternate with the sepals and often somewhat coherent 

 with them at the base, slightly perigynous, each furnished 

 with a petaloid appendage which is connate with their base, 

 imbricated in aestivation, the two upper exterior, these bear- 

 ing a petaloid inequilateral scale which is destitute of a 

 crest; the two anterior interior in the bud, more remote from 

 the stamens, and bearing each an unguiculate scale which 

 has an inflexed crested appendage on the inner side below 

 the apex. Disk produced on the lower side exterior to the 

 stamens into two rounded or elongated glands, one before 

 each of the anterior petals. Stamens 8, thrown by the an- 

 terior projection of the disk, with the pistil which they sur- 

 round, towards the upper side of the floAver : filaments dis- 

 tinct, or often monadelphous at the base, the anterior usually 

 shorter: anthers two-celled, introrse, the cells opening lon- 

 gitudinally. OvAiiY eccentric, often slightly stipitate, trian-
