 produced on one side; placentae deeply intruded, bifid, branches much 

 recurved bearing ovules on both surfaces. Capsule narrow-lanceolate, 

 longer than the calyx, follicular, afterwards 2-valved; valves twisted;

 somewhat unequal at the base, glabrous, 2-lipped ; lobes 5, ovate, obtuse. 

 Stamens 2 perfect, 2-3 rudimentary ; filaments short, linear (in the Indian 

 species) ; anthers 2-celled, often cohering at the apex ; cells ovate, divergent 

 at the base, slits usually confluent at the apex. Ovary sessile, linear ; disc

 2-lobed ; placentae inflexed nearly to the axis, then recurved bearing the 

 ovules. Capsule linear, loculicid'al ; valves 2, twisted ; placenta at first 

 attached to the valves, twisted with them, afterwards separating from the 

 valves, which often again split each into two. Seeds minute, ellipsoid, 

 smooth, testa minutely reticulate. — Species 12, Indian, N. Chinese, N.
