apple, the calyx is a cup or tube with the upper edge divided into
lobes.

Above the calyx is a broad spreading corolla which is white or
brightly colored and is divided into several distinct parts called
petals. The petals of one kind of flower are generally different in
shape, size and color from those of other flowers. In some flowers the
petals are united into a corolla of one piece which may be
funnel-shaped, as in the morning glory or petunia of the garden, or
tubular as in the honeysuckle, wheel-shaped as in the tomato and
potato, or of various other forms.

Within the corolla are found several bodies having long, slender stems
with yellow knobs on their tips. These are called stamens. The slender
stems are called stalks or filaments and the knobs anthers. The
anthers of some of the stamens will very likely be found covered with
a fine, yellow powder called pollen. This pollen is produced within
the anther which, when ripe, bursts and discharges the pollen.

The stamens vary greatly in number in different kinds of flowers. In
the centre of the cherry, peach, or mustard flower will be found an
upright slender body called the pistil. In the peach and cherry the
pistil has three parts, a lower rounded, somewhat swollen part called
the ovary, a slender stem arising from it called the style, and a
slight enlargement at the top of the style called the stigma. The
stigma is generally roughened or sticky. If the ovary is split open,
within it will be found a little body called an ovule, which is to
develop into a seed.

In the apple flower the pistils will be found to have one ovary with
