from perfect and completely closed ovaries. Moquin- 
Tandon’ cites from Agardh an instance which seems 
more closely to resemble the state of things in the 
Beckea, and which occurred in a double hyacinth, 
wherein both anthers and ovules were borne on the 
same placenta. Probably, though the fact is not 
stated, the ovary of the hyacinth was open; and we 
are told that the flower was double—that it was, in 
fact, modified and changed in more organs than one; 
while in the Beckea nothing at all unusual was ob- 
served till the ovary was cut open. The style was 
present even in those flowers where there was no 
axile placenta; hence in these cases it could not be, 
as Lindley stated it to be in the closely alhed Babing- 
tonia, a prolongation of the placenta.’ 
Formation of pollen within the ovules—This has now been 
recorded in two instances by Mr. 8. J. A. Salter in 
Passiflora cerulea and in P. palmata,’ and by the author 
in Rosa arvensis.* 
In the case of' the passion-flower there were various 
malformations in the ovaries, which were all more or
