grape showing adventitious grape mentary fruit in the interior. 
in the position of a seed. 
In the normal flower there is a turbinate hollow 
calyx, whose limb is divided into five serrated lobes ; 
alternating with these latter, and springing from the 
throat of the calyx, are the petals. Originating from 
the same annular disk as the petals are the stamens, 
seven or eight mm number. The ovary is partially adhe- 
rent, is surmounted bya style, and has two or three loculi 
with an axile placenta, to which several small curved 
ovules are attached. The malformed flowers did not 
present anything peculiar in their outer parts, nor did 
the ovary, partially immersed within the expanded top 
of the flower-stalk and the calyx-tube, which is con- 
tinuous with that organ, show externally any indica- 
tion of the change within. On cutting it across, 
however, in any direction, numerous perfect stamens 
(filaments and anthers) were seen. projecting from 
the walls of the cavity (fig. 98). In most of the 
flowers the ovary was one-celled; but in a few 
there was the usual axile placenta; yet even in these 
latter cases the stamens originated from the walls 
of the cavity, and not from the placenta. The stamens 
presented different degrees of development; in some 
cases they were fully formed, the anther-lobes open, 
and the pollen exposed; while in other instances the
