Sepals 3, small, elliptic or ovate, obtuse, concave. Petals 3, obovate,

more or less dissimilar anther, and 3-2 sterile, rudimentary or cruci- 
form; filaments with or without beaded hairs. Ovary 3~2-celled. 
Capsule ovoid to linear, 3-valved; seeds several (or 2-1) superposed in 
one vertical row (in the Tropica] African species) in each cell.—Panicles
