Wild Flowers: An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors
Blanchan, Neltje
Wild flowers -- North America
Because few writers have arisen as yet in the newly settled
regions of the middle West and Southwest, where blue-eyed Mary
dyes acres of meadow land with her heavenly color, her praises
are little sung in the books, but are loudly buzzed by myriads of
bees that are her most devoted lovers. "I regard the flower as
especially adapted to the early flying bees with abdominal
collecting brushes for pollen - i.e., species of Osmia - and
these bees," says Professor Robertson of Illinois, "although not
the exclusive visitors, are far more abundant and important than
all the other visitors together." For them are the brownish marks
on the palate provided as pathfinders. At the pressure of their
strong heads the palate yields to give them entrance, and at
their removal it springs back to protect the pollen against the
inroads of flies, mining bees, and beetles. As the longer stamens
shed their pollen before the shorter ones mature theirs, bees
must visit the flower several times to collect it all.
MONKEY-FLOWER
(Minulus ringens) Figwort family
Flowers - Purple, violet, or lilac, rarely whitish; about 1 in.
long, solitary, borne on slender footstems from axils of upper
leaves. Calyx prismatic, 5-angled, 5-toothed; corolla irregular,
tubular, narrow in throat, 2-lipped; upper lip 2-lobed, erect;
under lip 3-lobed, spreading; 4 stamens, a long and a short pair,
inserted on corolla tube; pistil with 2-lobed, plate-like stigma.
Stem: Square, erect, usually branched, 1 to 3 ft. high. Leaves:
Opposite, oblong to lance-shaped, saw-edged, mostly seated on
stem.
Preferred Habitat - Swamps, beside streams and ponds.
Flowering Season - June-September.
Distribution - Manitoba, Nebraska, and Texas, eastward to
Atlantic Ocean.
No wader is the square-stemmed Monkey-flower whose grinning
corolla peers at one from grassy tuffets in swamps, from the
brookside, the springy soil of low meadows, and damp hollows
beside the road; but moisture it must have to fill its nectary
and to soften the ground for the easier transit of its creeping
rootstock. Imaginative eyes see what appears to them the gaping
(ringens) face of a little ape or buffoon (mimulus) in this
common flower whose drolleries, such as they are, call forth the
only applause desired - the buzz of insects that become
pollen-laden during the entertainment.
Now the advanced stigma of this flower is peculiarly irritable,
and closes up on contact with an incoming visitor's body, thus
exposing the pollen-laden anthers behind it, and, except in rare
cases, preventing self-fertilization. Delpino was the first to
guess what advantage so sensitive a stigma might mean. Probably
the smaller bees find the tube too long for their short tongues.
The yellow palate, which partially guards the entrance to the
nectary from pilferers, of course serves also as a pathfinder to
the long-tongued bees.
