The
single
flower
is
shown
enlarged
in
Fig.
19--A,
a
young
blossom,
with
analyses
B
and
C,
the
latter
indexed;
D,
an
older
blossom,
with
similar
analyses
(E
and
F).
Both
sorts
are
to
be
found
upon
every
spike
of
bloom,
as
the
inflorescence
begins
at
the
base
and
proceeds
upward.
As
we
look
into
the
more
open
flower
we
observe
a
dark-colored
speck,
which,
by
analysis,
proves
to
be
the
lid
of
the
anther.
This
portion
is
further
shown
enlarged
in
Fig.
20,
A.
If
we
gently
lift
it
with
a
pin,
we
disclose
the
pollen
masses
in
the
cavity
(B)
thus
opened
(C,
profile
section),
the
two
pairs
united
to
a
common
viscid
gland
at
the
base,
this
gland
again
secreted
behind
a
veil
of
moist
membrane,
as
also
shown
at
B.
This
membrane
is,
moreover,
very
sensitive
to
the
touch.
Below
the
flattened
tip
of
the
column,
and
at
a
sharp
inward
angle,
is
the
stigma.
In
the
freshly
opened
flower
(Fig.
19,
A)
the
column
inclines
forward,
bringing
the
anther
low
down,
and
its
base
directly
opposite
the
V-shaped
orifice
in
the
lip,
which
also
is
quite
firmly
closed
beneath
the
equally
converging
upper
hood
of
the
blossom.
The
entrance
is
thus
much
narrowed.
If
we
insert
a
pin
in
this
V-shaped
entrance
it
comes
in
contact
with
the
sensitive
membrane
below
the
anther,
and
it
is
immediately
ruptured,
as
shown
at
Fig.
20,
D.
The
sticky
gland
is
brought
into
immediate
contact,
and
clasps
the
pin,
which,
now
being
withdrawn,
brings
away
the
pollen,
as
in
E
and
F.
Thus
it
is
naturally
removed
on
the
tongue
of
its
sipping
bee.
