The curved bodies at the base of the stalks, are I iraagiue, what 

 I have elsewhere called antheriform bodies. J. 



Fig. Vila. — Represents a sporule after separation from the plant, 

 lying in the body, either involucre or ovalum, at the bottom of a 

 goblet. It is of a pale whitish green tint. 



Azolla pinn ata, PI. CXX. (continued.) 



Fig. III. — L. Represents parts of the contents of a pedicellate 

 body, (Capsule) 1-16, shewing the yellow sacs contained in pa- 

 rent cells ; the membrane of which is scarcely formed. 



2. Represents the contents of a more advanced pedicellate body, 

 (Capsule). The appearances is now a good deal changed, instead, 

 of as many cells, as groups of yellow sacs, or instead 

 of the yellow sacs being 3-4 in each cell, they are several ; this 

 is one of the great anomalies, several of the yellow sacs are 

 evidently abortive. 



3. Represents a pair of bodies, very young, under pressure; one 

 accidentally ruptured, granules have past out. This shews 

 well the condensing grume in the nucleus, and the early ex- 

 istence of the cellular protuberances round the base of the 

 nucleus.

6, Two pistilliform bodies, J C. Lens, measured. Apex of tho 

 smaller one distinctly hyaline, umbilicate, disclosing confervoid fila- 

 ments passing out ; then the uninverted funnel shaped part ; then the 

 nucleus or grumous cell which appeared erect, attached by a broad 

 base. The base of the pistillum opaque, but the rest penetrable; 

 the passage out of the filaments most distinct. 



The larger one of the pair, with a mucilaginous dissolved look- 

 ing, browned, more obtuse apex, not distinctly umbilicate, and with 

 no evidence of perforation, or of a tube, the larger confervoid fil t- 

 ment appeared to pass into its apex obliquely. The nucleus the same. 

 Each cell of the superficies of both, parallelogrammic, and in all ex- 

 cept perhaps the cells of the apex ; a, nucleus of greenish colour ; c. 

 represents the confervoid filamentous structure at different foci, d. d. 

 are the most correct. 1-16 M.
