plants : for here we not only have sporules produced, but a 

 highly complicated covering etc. for them. 



Several things led me to suppose that impregnation does 

 take place, and in particular the sphacelation of the style : 

 neither is this weakened by the fact such takes place in most 

 of the female flowers, analogus instances occuring in some 

 Phaenogams as in Santalum. 



The growth of the seta is highly curious, and was first 

 pointed out I believe by Valentine in a paper read before the 

 Linnean society. 



It is particularly remarkable for this : that supposing im- 

 pregnation to take place, the changes ought to occur in the 

 vesicle itself, whereas we have seen that this never enters into 

 the composition of the theca, but always forms the extreme 

 apex of the included real apex of the seta. 



Palisots idea is all wrong, because the columella is invariably 

 solid. 



Funaria PI. CIX. 



1. Male body or anther with two of the singularly 

 beautiful cellular processes which always occupy the 

 centre, the anther appears open. 



2. Male bodies in different stages of developement. 



a mature \ attached is one of the cellular articulate pro- 

 cesses. 



3 ) 



4*> Arbortive Pistilla. 



5. Three Pistilla from one female inflorescense. 



6. 6a. 6b. 6c. Four do. from another inflorescence, these 

 have various developements, and all have been impreg- 

 nated. 



6. Shews the first change in the Pistilla, consisting either 

 in the enlargement of a pre-existing cell, or (and I think 

 this most probable), the formation of a cavity for the 

 commencement of the seta. 



6a. Is the most developed : 6a bis, is the apex of the young 

 seta detached.
