1. Portion of a frond with male inflorescence in different 

 . stages. 



2. Section of an antheriferous cavity. 



3. Do. at a more advanced stage. 



4. Fasciculus of anthers with the floor of the antheriferous 

 cavity, shewing that there exists in one fasciculus all 

 stages of developement. 



5. Perfect anther hefore dehiscence, viewed as a transparent 

 ohject. 



6. Portion of its contents. 



7. Anther after dehiscence. 



8. 9. Sections of fronds and involucra shewing the young 



capsule tipped with the dislocated cellular tissue. 



10. Young capsule detached. 



11. Do. wall of the capsule removed. 



12. Cellular cap of do. Calyptra of Sprengel etc. 



13. Upper portion of a capsule after eruption from the in-

Anthoceros P. LXXV. F. Fig. II. 



1. Long section of portion of a frond carried through the 

 point of developement of the future female organ at a 

 very early period. The funnel shaped membrane has 

 already made its appearance. The first steps are seen 

 to consist of a thickening of part of the tissue which 

 subsequently becomes the bulbous base of the capsule. 



'2. The same at a rather more advanced stage. 



Do. more advanced, the dislocation or breaking up of the 

 tissue between the apex of the very young capsule and 

 that of the involucrum is very distinct. 



4. A somewhat oblique section of a rather more advanced 

 stage, shewing the mode in which the funnel-shaped 

 membrane is spread over the apex of the young involu- 

 crum. Portion of it is reflexed.
