The structure, as I have described it, agrees with the general- 
ization of Grassmann * for all Liliaceze with septal glands, except 
Allium, where the original opening of the gland is lower, but 
otherwise similar. It can be made out by careful longitudinal 
sections like that figured, or even better by breaking the fresh 
ovary lengthwise between two carpels, when the full length of 
the gland is easily laid open. I have also convinced myself that 
there is no connection with either the ovarian cells, the intrastylar 
canal or the stigmatic cavity that prolongs them both, by cutting 
serial cross-sections of the ovary like that represented in figure 2, 
through the entire length of the pistil, repeating them many times 
at the critical points, namely, the top and bottom. 
There is a more or less prevalent opinion that the glands of 
plants and animals differ in the superficial character and greater 
simplicity of the former; excepting, of course, those internal 
resin and oil passages which do not open for the liberation of their 
secretion—e. g., the resin passages of Coniferz and the oil recep- 
tacles of the orange, mints, etc. It is true that the number of 
vegetable glands which are situated within the plant but discharge 
their secretion at the surface through a duct-like opening is 
small, as I endeavored to show in an unpublished communica- 
tion to the Boston Society of Natural History a number of years 
ago; but they are occasionally met with. The follicles at the 
mouth of Nepenthes pitchers, described, I believe, by Mr. Potts 
in the Proceedings of the Philadelphia Academy, some years since, 
are the simplest type of this sort of structures, to which also be- 
long the protective nectar glands on the peduncles of the Cow 
Pea (Dolichos sp.), which I figured in the American Bee Journal, in 
1880; and presumably in the similar organs of species of Apzos 
and Phaseolus. These latter organs, which correspond to abor- 
tive flower buds, are very complex and will well repay a careful 
study of their developmental history. 
The nearest approach to such lobulated glands of animals as 
the salivary glands is, however, found in the ovarian glands of 
the endogens. Insome cases? these are produced into contracted
