Most
of
my
readers
are
familiar
with
the
general
construction
of
a
flower,
but
in
order
to
insure
such
comprehension
it
is
well,
perhaps,
to
freshen
our
memory
by
reference
to
the
accompanying
diagram
(Fig.
2)
of
an
abstract
flower,
the
various
parts
being
indexed.
The
calyx
usually
encloses
the
bud,
and
may
be
tubular,
or
composed
of
separate
leaves
or
sepals,
as
in
a
rose.
The
corolla,
or
colored
portion,
may
consist
of
several
petals,
as
in
the
rose,
or
of
a
single
one,
as
in
the
morning-glory.
At
the
centre
is
the
pistil,
one
or
more,
which
forms
the
ultimate
fruit.
The
pistil
is
divided
into
three
parts,
ovary,
style,
and
stigma.
Surrounding
the
pistil
are
the
stamens,
few
or
many,
the
anther
at
the
extremity
containing
the
powdery
pollen.
Although
these
physiological
features
have
been
familiar
to
observers
for
thousands
of
years,
the
several
functions
involved
were
scarcely
dreamed
of
until
within
a
comparatively
recent
period.
In
the
writings
of
ancient
Greeks
and
Romans
we
find
suggestive
references
to
sexes
in
flowers,
but
it
was
not
until
the
close
of
the
seventeenth
century
that
the
existence
of
sex
was
generally
recognized.
