Shrubs or partially woody herbs, with erect, often tufted, or decumbent or reclining

 bearing 2 large basal glands ; petals 5, unequal in size and shape, the blades broad, clawed, 

 fimbriate all around ; stamens 5, but only 2 with perfect anthers, the filaments partially 

 united, the 2 bearing perfect anthers more united than the others ; carpels 3, with elongate 

 styles. Cleistogamous flowers sessile in the lower axils, or terminating axillary peduncles ; 

 carpels 2, with obsolete styles, only one usually maturing ; nutlets obliquelj- attached, each 

 with a median ridge or crest and rounded or angled or margined sides, the faces usually 

 wrinkled.
