stems may be mentioned. For example, near the base of the 
organ, that is, near the point of its attachment to the stem, the 
cells described as dividing to form the small cells are like those of 
the pith, as shown by the markings of their walls. They lie also 
in such a position as to indicate their connection with the pith 
rather than the rind cells. Owing’ to this, the bands which they 
form appear to connect the xylem parts of the bundles rather than 
the cambium layer. 
At the other extremity, or near the growing region, this is not 
so evident, though the beginning of the division of these cells was 
found in a section one centimeter from the fruit. 
Near the inner extremity of each bundle is a group of See 
Which have been referred to above as resembling the tannin cells 
of the family Leguminosae. There are usually several of these 
in a cluster, so arranged as to form a semicircle in the transverse 
section, whose concave side is toward the bundle. In the long 
section they liein continuous rows. They correspond in size and 
shape to the larger pith cells, and are conspicuous on account of 
their deep brownish-yellow color. 
The pith is composed of cells which appear circular in a cross 
section, and in a long section are seen to be somewhat elongated 
like the other cells of the ground system. The cells composing 
the outer edge of the pith are of about the same diameter as those 
of the rind tissue, but they increase in size as the centre is ap- 
proached. They are provided with numerous pores on the radial 
and periclinal walls; these are linear or slit-like, and are ar- 
ranged with their long diameters running obliquely from right to 
left. On the anticlinal walls, instead of pores, markings very 
similar to those of reticulated ducts occur. 
The anatomy of the subterranean part of the gynophore 
differs from that above ground in the following respects: (1st) 
Most of the epidermal cells grow out into long hairs. (2nd) 
À growth in thickness occurs by a process similar to that of peri- 
derm formation, by which the diameter of the subterranean part 
is considerably increased. (3rd) By the absence of plasmolytic 
cells in the rind described above. 
Nearly all of the epidermal cells develop long thin-walled 
one-celled hairs. These average about .8 mm. in length and are
