wise. The epidermal cells of the aerial portion show, on a cross 
section, a nearly oval lumen with a longer tangential diameter. 
A long section shows the length of the cells to be about three 
times their tangential diameter. Allthe walls are slightly thickened. 
These cells are interrupted by occasional stomata occurring about 
three to a square millimetre. 
The rind, or that part of the ground-tissue extending between 
the epidermal layer and the bundle-cylinder, is about eight cells in 
depth. These cells are thin walled, of a nearly circular appear- 
ance, seen in a cross section, and with frequent intercellular spaces. 
In a long section their length is seen to correspond with the epi- 
dermal cells. 
About half way between the epidermis and the bundle-cylinder 
a row of cells of peculiar character occurs. They appear to have 
a much longer tangential than radial diameter. But on examining 
them carefully they are seen to be completely plasmolytic, the 
radial walls lying in folds, which gives the appearance spoken of 
above. This row of cells was constant in the sections of the 
aerial portion of the gynophores examined. This circumstance is 
extremely puzzling, as no explanation can be offered for the 
phenomenon of plasmolysis in cells so situated. 
The bundles are arranged in a circle according to the type of 
dicotyledonous stems. Through the greater part of the length of 
the gynophore they are constantly thirteen in number, but at either 
end, that is near the fruit or near the stem, they vary from this, 
numbering sometimes more and sometimes fewer. The circle of 
bundles with the tissue between them may be described as a hol. 
low cylinder enclosing the pith. The individual bundle is covered 
toward the periphery by a partial sheath which extends laterally 
no further than the bast. This sheath is composed of one layer 
of cells which are smaller than the cells of the parenchyma of the 
rind and nearly isodiametric, and their anticlinal walls are fre- 
quently oblique. 
The outline of the bundle itself, as seen on a cross section, is 
oval with the smaller part toward the centre. The outer part of 
the bundle is occupied by a heavy cluster of bast cells, which is 
convex toward the rind and slightly concave on its inner side. 
The remaining elements of the phloem were not distinctly made
