are usually cleft at the apex, whence it sometimes appears 4- 
valved; but usually dehiscing at the cells, rarely at the disse- 
piment. Placentas central. Seeds numerous, small, ovate, 
angular, usually only 2 in each cell at maturity.—Small trees or 
shrubs, mostly natives of America. Leaves almost sessile, or

solitary on both sides, undivided, sometimes hairy inside. Pe- 
duncles axillary, usually trichotomous, sometimes disposed in a 
terminal corymbose panicle, rarely 3 or 1-flowered.—All the 
Asiatic plants referred to this genus are species of Wendldndia.
