Asiatic species, has not been adopted. The principal points 

 to be noticed in regard to the fructification are his consider- 

 ing (with Mr. Brown,) the calyptrate capsule to be the male 

 organ, and the globular capsule containing the pedicelled se- 

 condary capsules to be the female ; his not having been able 

 to ascertain the presence of the yellow sacs, each containing 

 four bodies, figured by Martius in the contained masses, (his 

 seeds) ; and his stating that the root-like prolongations are 

 confined to their flattened edges, and not, as represented 

 by Martius, scattered over the whole surface. M. Meyen's 

 inner calyptra of the male is the nucleary membrane ? 

 M. Meyen mentions the original nucleus of the capsules 

 containing the pedicellate secondaries, as a pestle-shaped 

 body, terminating the column to which they (his partial 

 indusia,) are attached. 



The later descriptions of Sprengel and Endlicher are 

 compilations. 



Sprengel* calls the capsules receptacles, and states them 

 to be axillary ! Some of these are described as transversely 

 bilocular, the upper-cell containing triangular bodies attach- 

 ed to a common axis, the under-cell containing a mucous 

 latex or subsequently a powdery mass. The others which 

 are said to be covered by a double membrane ! contain 

 pedicelled globules, each divided into three triangular 

 corpuscles furnished with radicles. 



The best part of this curious character appears to be 

 taken from the character in Flinders's Appendix, and as re- 

 gards the contents of the pedicelled secondary capsules, 

 from figure 17 of M. Bauer. 



It is, I think, instructive to observe, that with the excep- 

 tion of the term receptacula, this character presents no 

 analogy with those of the other genera with which it is 

 classed : even the similarity of the pedicelled spherical
