The Fairy-Land of Science

We
have
now
seen
how
a
plant
springs
up,
feeds
itself,
grows,
stores
up
food,
withers,
and
dies;
but
we
have
said
nothing
yet
about
its
beautiful
flowers
or
how
it
forms
its
seeds.
If
we
look
down
close
to
the
bottom
of
the
leaves
in
a
primrose
root
in
spring-time,
we
shall
always
find
three
or
four
little
green
buds
nestling
in
among
the
leaves,
and
day
by
day
we
may
see
the
stalk
of
these
buds
lengthening
till
they
reach
up
into
the
open
sunshine,
and
then
the
flower
opens
and
shows
its
beautiful
pale-
yellow
crown.
We
all
know
that
seeds
are
formed
in
the
flower,
and
that
the
seeds
are
necessary
to
grow
into
new
plants.
But
do
we
know
the
history
of
how
they
are
formed,
or
what
is
the
use
of
the
different
parts
of
the
bud?
Let
us
examine
them
all,
and
then
I
think
you
will
agree
with
me
that
this
is
not
the
least
wonderful
part
of
the
plant.
Remember
that
the
seed
is
the
one
important
thing
and
then
notice
how
the
flower
protects
it.
First,
look
at
the
outside
green
covering,
which
we
call
the
calyx.
See
how
closely
it
fits
in
the
bud,
so
that
no
insects
can
creep
in
to
gnaw
the
flower,
nor
any
harm
come
to
it
from
cold
or
blight.
Then,
when
the
calyx
opens,
notice
that
the
yellow
leaves
which
form
the
crown
or
corolla,
are
each
alternate
with
one
of
the
calyx
leaves,
so
that
anything
which
got
past
the
first
covering
would
be
stopped
by
the
second.
Lastly,
when
the
delicate
corolla
has
opened
out,
look
at
those
curious
yellow
bags
just
at
the
top
of
the
tube
(b,2,
Fig.
43).
What
is
their
use?
