ORGANOGENY OF THE GYNOECIUM 
The form, size and structure of the ovary varies much in 
the different genera and species. The ovary, in all cases 
inferior, may contain one seed, as in Szcyos, or many, as in 
Cucurbita, distributed in various ways presently to be de- 
scribed. 
As early as 1682 Nehemiah Grew”™ in his Anatomy of 
Plants described the structure of the ovary and the manner 
of placentation in Cucum7s satévus. He says, ‘* The middle 
parenchyma is divided into three columns which stand triang- 
ularly, having each of them a triangular figure.” ‘* These 
columns are, as it were, beds on which the seeds grow.” 
He found the ovary divided into six triangles and each tri- 
angle to contain three ‘‘ ovals.” 
Gaertner * more than one hundred years later described 
and figured the more obvious structural features of the seeds 
and ovaries of Szceyos, Bryonta, Momordica, Cucurbita, Cu- 
cumis and Lagenarza. Wis figures, though not very clear 
in all points, show very well the divisions of ovary and the 
parietal attachment of the seeds in Cucumzs and Cucurbita, 
In 1815 Mirbel,® in describing the form of fruit known as 
a pepo refers to the structure of the ovary of the Cucurbi- 
taceae. His reference is particularly to Cucurbzta and 
Cucumes, and he states that the ovary is divided into many 
locules by radiating placentae, the lobes of which are 
bordered by nerves which bear the ovules, the latter being 
borne in two ranks on each lobe. In some cases, he points 
out, locules are divided each by a pulpy wall. 
Brongniart * (1826) described the anatomy of the ovary of 
Cucurbita Pepo with special reference, however, to the con-
