Calyx herbaceous, of 5 sepals more or less united at the 

 base, quincuncially imbricated in aestivation, persistent. Pe- 

 tals 5, hypogynous, obovate or cuneiform, convolute-imbri- 

 cated or entirely convolute in aestivation (imbricated, Endl., 

 etc.), marcescent-persistent. Stamens 5, hypogynous, alter- 

 nate with the petals : filaments filiform or subulate, per- 

 sistent : anthers extrorse, immovable, two-celled ; the cells 

 often somewhat separated, opening externally by a longitu- 

 dinal line : poLLEN-grains united in fours. Ovary globular, 

 one-celled : styles 3 or 5, alternate with as many parietal 

 placentae, simple, penicillate-multifid, or more commonly 

 two-parted, with linear or clavate divisions stigmatose on 

 the inner side. Ovules numerous, in two or more series 

 occupying the whole length of the parietal placentae, hori- 

 zontal, anatropous. 



Capsule partly covered by the persistent calyx, one-cell- 

 ed, loculicidally 3 - 5-valved ; the valves bearing the nervi- 

 form many-seeded placentae on their middle for their whole 

 length. Seeds scobifonn, the loose and cellular testa very 

 much larger than thp nucleus, or oblong with the cnista-
