AOOTYLBDONOUI plants. 



I Kssential points! for consideration with reference to fc 



emulation. 



1 Prior development, of (lie nucleus. 



2 The absence of grains in the neck of the uvulum be- 

 fore the entrance or attachment of the Confervoid Fila- 



ncntii 



It The absence of sphacclat ion before the attachment of 

 the name. 



II Kssential points with reference to the development. 

 The minute examination of both ovula in order to ascer- 



tain if there is any dilVerence in the mode of fecundation. 



'J. The minute examination of the frondose mass at early 

 slaves, to reconcile it. with the ordinary development of 

 Hporcn. 



'A. The minute examination of the process of confer-ru- 

 Dfllnation, and number of germinating points. 



MUSCI AND IJEPATICJE. 



8. It is a remarkable fact that in Musci, ami the vaginulate 

 Ilepatitve, the ovnlum undergoes no change except iu situa- 

 Ution, it forming the tip, or point of the seta. And that, in 

 Azolla, the nucleus undergoes no change whatever, being de- 

 tect ihle even when the spores are completely conjerrnminate. 



li is only changed analogously, to non vaginulate llepa- 

 tiete. in the frondose-producing one. 



Memo. Hear in mind the unchanged nucleus being the 

 apex of the axis, and the pedicellate bodies being developed 

 round its base, from above downwards, this is in favour of its 

 being due to fecundation. 



The analogy of Chara, is in favour" of the frondose mass, 

 and big yellow sac-like body, being the developed female. 



To what can the capsule of Mosses and Jungerinanniacca' 

 be strictly rendered analogous?. The question is reduced 

 somewhat in iliiliculty if we examine the last, for in these 

 the cell pre existing iu the cavity of the I'istillum, is deve- 

 loped by fccund.it ion into a simpler form of reproductive 

 M-gau.
