 anther, dehiscing by two longitudinal clefts.' The largest, alternate 

 Avith the preceding, has long filaments and anthers with extrorse 

 or marginal dehiscence.- In the female flowers the perianth is 

 generally the same, but the androceum totally disappears, or is only 

 represented by one or two verticils of sterile tongues. The glands 

 of the hypogynous disk arc free or united among themselves, and 

 the superior gyuisceum is composed of an ovary with three cells, 

 surmounted by a style whose three bifid branches are stigmatiferous 

 above and within. In the inner angle of each cell, the placenta sup- 

 ports a descendent ovule, constructed like that of Ricinus, and 

 surmounted iu the same way by a cellular obturator.^ The fruit is 

 a capsule generally tricoccate, opening elastically, and allowing the 

 arillate seeds to escape similar in all respects to those of Ricinus and
