In Cicer arietinum ditto ditto, (quintine developed inside 
and before the quartine.) 
Lupinus varius ditto ditto. < 
Phaseolus coccineus ditto ditto. 
Anagallis arvensis ditto ditto. 
In Cucumis Anguina, the embryonary sac is quintine, 
quartine none. 
In Euphorbia Lathyris the sac is the quintine, quartine 
none, and I opine, that the nucleus is represented as the 
secundine; in this case the more opaque inner layer of the 
primine will be the secundine. This will agree well with 
Brongniart’s observation. 
In Statice the quintine is probably a development extra- 
ordinary of the filet suspenseur, perhaps it is the embryo- 
nary sac, in which case M. Brongniart's quartine will be nu- 
cleus ; this would be conformable. 
^ In Mire Pennsylvanica, the embryonary sac is quiiitide; 
the nucleary membrane is either nucleus or quartine! Mirbel 
is not certain which. 
In Tradescantia virginica, the embryonary sac is quartine. 
In Polygonum tataricum, M. Mirbel's explanation is at 
first right, but subsequently, reasoning on the assumed possi- 
bility of the nucleus even at this early period disappearing 
entirely, he almost makes the nucleus the secundine. Again 
in another figure, his quartine is nucleary membrane, or ter- 
cine, and his quintine, quartine or embryonary sac. 
M. Mirbel is of opinion, that his quintine is the sac of the 
amnios of Mr. Brown, and that this gentleman has erred in 
stating that it is of uncommon occurrence. 
Mr. Brown says—* the membrane of the nucleus usually 
constitutes the innermost coat of the seed. But in a few 
plants an additional coat, apparently originating in the inner 
membrane of Grew, the vesicula-colliquamenta, or amnios of 
Malphighi also exists." But this passage will not bear the 
construction when viewed in conjunction with the subse-
