Sepals 3, distinct or more or less connate. Petals 6, in two series, or 

 rarely 3, one series being suppressed, free or shortly connate at the base, val- 

 vate or imbricate in aestivation. Stamens indefinite, numerous (10 or fewer 

 in Clathrospermum) , free, usually closely imbricate upon a convex or rarely 

 plane torus ; filaments short or 0. Anthers adnate, linear, cuneate or quad-

 distinct, 1- or several-seeded, sessile or stipitate, usually indchiscent, or se-
