 Mitli 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 hypogyuous disk are free or united among themselves, and 

 the superior gyna3ceum is composed of an ovary with tlii-ee 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 Eichius, and 

 surmounted in the same ^^-ay by a cellular obturator.^ The fruit is 

 a capsule generally tricoceate, opening elastically, and allowing the 

 arillato seeds to escape similar in all respects to those of Ilicinus and 

 Eiijihorhki.

Tu some species oi Jatrophn^ the number of stamens is increa.sed to 

 twenty or thirty. In others, the male flower alone has a corolla, 

 which is wanting in the female flower. In others, again, of which 

 it has been thought a genus might be made, under the name of 

 CalduscolaXj'' (figs. 16G, 1G7), the petals disappear in the flowers of 

 both sexes,*when the calyx generally becomes petaloid. In J. Curas

- The summit of the androceum column sup- 

 ports, in a certain number of llowcrs, a rudi- 

 ment of a gyna'Ccum, sometiiucs entire, some- 

 times trifid or tripartite, the existence ol' which 

 has been contested (see Atluiisonin, xi. 131).
