tachraent of the nucleus, rather than to any stigmatic ap- 

 paratus. 



M. Fabre says nothing of sphacelation of the stigma, which 

 it ought to present, if really stigmatic. 



III. AZOLLA. 



Azoi.la pin n ata, PL CXIX. 



Fig. I., — 1. Confervoid filaments attached to the axis near the 

 reproductive organs. I only saw these appearances in [one 

 instance. 1-16. 



2. Represents the contents of the nucleus dissected out (but dis- 

 turbed), it shows however, that there are more membranes deve- 

 loped round the condensed points than the subsequent number 

 of lobes (9) for here on one face there are 7. The grumous 

 mass below the yellow sac, is there from misplacement. 



3. One of the ovate oblong bodies : parts seen in situ, a few 

 grains still remain. In this also there are more membranes 

 than subsequent lobes The yellow sac is of this form from 

 pressure. 



4. Very young state of the reproductive organs, young involucre 

 pushed back : confervoid filaments pass from the receptacle, but 

 not with positive relations to the omda in young reproductive 

 organs. 



5. Young state of the pedicellate globose body, shewing the divi- 

 sion of the cells imbedded in its grume, parts in situ. 



Fig. U. — Represents a very young involucre: evidently open at 

 top, from which protruded two confervoid filaments ; it contained 

 one very young pistillum, the nucleus of which was beginning to be 

 enclosed in the tegument. 



Fig. I la, — Involucrum very young. 



Fig. III. — In this instance, one only presented clearly the commu- 

 nication and the sac, apparently filled with granules, or itself granu- 

 lar, the other presented neither distinctly, but from this protruded ?
