SALVINIA.

12. One of the bodies intermixed with young capsules. 

 All but 46. and 8. J C. L. M. 



9a. Represents one of the future three bodies, the membrane is 

 scarcely definable, and I never saw it with a double edge, it is 

 just what one would imagine to arise from gaseous matter con- 

 tained in minute grume and mucilage; it presents a grumous 

 nucleus of irregular shape. 



III. SALVINIA. 

 Salvinia verttcillata, PI. CXXIII. 



-p\g, II. — Ovulum, terminating the axis,most of the hairs removed. 

 I observed one (not represented) like the confervoid filaments of the 

 roots. Grume plainly adhering to the foramen, and also I think 

 filling the space (or at least adhering to the walls) between the 

 nucleus, or rather sporangia, and the mouth. 



This would have been a capsule containing the few oblong bodies, 

 so the change on which one part depends takes place very early. 

 It is only cognisable by the greater or less size. 



pjo. iv. — 8. Young capsule, and a nascent secondary one, J. 



Hairs all removed. 

 9. Nascent ditto, as seen under pressure, J, the terminal cell larger 



than the next to it. 



10. One of the cellular bodies (future capsules) of the larger 

 young capsule, of which they occupy the whole fundus, being 

 exceedingly numerous. 



11. The same shewing the usual preparatory steps to the forming 

 of cellularity. 



Fig. V. — 1. One of the sphaerical more numerous capsules 1-16, 

 whole cavity occupied by grume, in which are imbedded tri- 

 facial cells, with anylaceous green granules in irregular groups 

 of cells within the pariete3 of spherical capsule. 



Fig. III.— One of the oblong larger spherical capsules, the space 

 between the central large body, and wall is occupied by fluid 

 grume, which escapes on very slight pressure, in it a few trifaci- 

 al cells occur. 1-10.
