=The flowers= are pendant and borne in more or less branched clusters,
located on the stem on the opposite side and usually a little below the
leaves; the first cluster on the sixth to twelfth internode from the
ground, with one on each second to sixth succeeding one. The flowers
(Fig. 2) are small, consisting of a yellow, deeply five-cleft,
wheel-shaped corolla, with a very short tube and broadly lanceolate,
recurving petals. The calyx consists of five long linear or lanceolate
sepals, which are shorter than the petals at first, but are persistent,
and increase in size as the fruits mature. The stamens, five in number,
are borne on the throat of the corolla, and consist of long, large
anthers, borne on short filaments, loosely joined into a tube and
opening by a longitudinal slit on the inside, and this is the chief
botanical distinction between this genus and _Solanum_ to which the
potato, pepper, night shade and tobacco belong. The anthers in the
latter genus open at the tip only. The two genera, however, are closely
related and plants belonging to them are readily united by grafting. The
Physalis, Husk tomato or Ground cherry is quite distinct, botanically.
The pistils of the true tomato are short at first, but the style
elongates so as to push the capitate stigma through the tube formed by
the anthers, this usually occurring before the anthers open for the
discharge of the pollen. The fruit is a two to many-celled berry with
central fleshy placenta and many small kidney-shaped seeds which are
densely covered with short, stiff hairs, as seen in Figs. 3 and 4.

It is comparatively easy to define the genus with which the tomato
should be classed botanically, but it is by no means so easy to classify
our cultivated varieties into botanical species. We have in cultivation
varieties which are known to have originated in gardens and from the
same parentage, but which differ from each other so much in habit of
growth, character of leaf and fruit and other respects, that if they had
been found growing wild they would unhesitatingly be pronounced
different species, and botanists are not agreed as to how our many and
very different garden varieties should be classified botanically. Some
contend that all of our cultivated sorts are varieties of but two
distinct species, while oth
