In
another
allied
example
of
the
orchids--the
Showy
Orchid--we
have,
however,
what
would
appear
a
clear
adaptation
to
the
head
of
a
bee,
though
one
which
might
also
avail
of
the
service
of
an
occasional
butterfly.
A
group
of
this
beautiful
species
is
shown
in
my
illustration.
A
favored
haunt
is
the
dark
damp
woods,
especially
beneath
hemlocks,
and
with
its
deep
pink
hood
and
pure
white
lip
is
quite
showy
enough
to
warrant
its
specific
title,
"spectabilis."
An
enlarged
view
of
the
blossom
is
seen
in
Fig.
7,
and
in
Fig.
8
a
still
greater
enlargement
of
the
column.
I
have
seen
many
specimens
with
the
pollen
masses
withdrawn,
and
others
with
their
stigmas
well
covered
with
the
grains.
Though
I
have
never
seen
an
insect
at
work
upon
it
in
its
haunt,
the
whole
form
of
the
opening
of
the
flower
would
seem
to
imply
a
bee,
particularly
a
bumblebee.
If
we
insert
the
point
of
a
lead-pencil
into
this
opening,
thus
imitating
the
entrance
of
a
bee,
its
bevelled
surface
comes
in
contact
with
the
viscid
discs
by
the
rupture
of
a
veil
of
membrane,
which
has
hitherto
protected
them.
The
discs
adhere
to
the
pencil,
and
are
withdrawn
upon
it
(Fig.
9).
At
first
in
upright
position,
they
soon
assume
the
forward
inclination,
as
previously
described.
The
nectary
is
about
the
length
of
a
bumblebee's
tongue,
and
is,
moreover,
so
amply
expanded
at
the
throat
below
the
stigma
as
to
comfortably
admit
its
wedge-shaped
head.
The
three
progressive
diagrams
(Fig.
10)
indicate
the
result
in
the
event
of
such
a
visit.
