least, before its fertilization. The bud at this stage is almost mi- 
croscopically small The ovary may be described as sessile, 
though there are a few layers of cells between its cavity and the 
. place of insertion of the succeeding organs, the stamens. The 
basal or lower part of its cavity is nearly rectangular in shape; the 
ovules are attached to the parietal placenta by short stems. The 
bundles passing through the base of the ovary, or that part which 
. may be considered the stem, number from 11 to 13. They ex- 
tend through to the tip of the ovary, branching more or less in 
their course. 
They consist of ducts with closely wound spiral markings, ac- 
companied by very delicate elongated cells in which individual 
characteristics cannot be determined. There is also a certain cluster 
of cells lying near each bundle on the side toward the centre of 
the organ. They are so near the bundle as to suggest some func- 
tional relation with it. These cells are large, prismatic in shape 
and filled with an orange colored substance; they correspond to 
those occurring frequently in the Leguminosae, which are known as 
tannin cells. 
After the egg is formed and fertilized the rudimentary stem 
begins to elongate and develop into the gynophore. The develop- 
ment of the young embryo was not studied, but the ovary itself 
remains nearly in the condition now described until the gyno- 
phore completes its growth. This may be seen from the fact that 
it does not increase perceptibly in size, but its extreme tip elongates 
slightly and is sharpened to an almost hair-like point. While the 
anatomy of the gynophore corresponds to that of the stem of any 
herbaceous dicotyledon, its manner of development resembles that 
of ordinary roots, as there are no lateral appendages and conse- 
quently no internodes. 
The cluster of meristematic or dividing cells which give rise 
to it consists of those lying just below the ovary. For convenience 
in description we may divide this cluster into three parts: first, 
those cells which give rise to the central cylinder and which lie 
immediately below the cavity of the ovary; second, those produc- 
ing the bundle cylinder, and lastly, those outside both of these, 
Which form the rind tissue, or the hollow cylinder outside the 
bundles,
