Wild Flowers: An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors
Blanchan, Neltje
Wild flowers -- North America
>From New Jersey and Illinois southward, particularly in
mountainous regions, if not among the mountains themselves, the
FRINGELESS PURPLE ORCHIS (H. perarnoena) may be found blooming in
moist meadows through July and August. Moisture, from which to
manufacture the nectar that orchids rely upon so largely to
entice insects to work for them, is naturally a prime necessity;
yet Sprengel attempted to prove that many orchids are gaudy shams
and produce no nectar, but exist by an organized system of
deception. "Scheinsaftblumen" he called them. From the number of
butterflies seen hovering about this fringeless orchis and its
more attractive kin, it is small wonder their nectaries are soon
exhausted and they are accused of being gay deceivers. Sprengel's
much-quoted theory would credit moths, butterflies, and even the
highly intelligent bees with scant sense; but Darwin, who
thoroughly tested it, forever exonerated these insects from
imputed stupidity and the flowers from gross dishonesty. He found
that many European orchids secrete their nectar between the outer
and inner walls of the tube, which a bumblebee can easily pierce,
but where Sprengel never thought to look for it. The large lip of
this orchis is not fringed, but has a fine picotee edge. The
showy violet-purple, long-spurred flowers are alternately set on
a stem that is doing its best if it reach a height of two and a
half feet.
WATER-SHIELD or WATER TARGET
(Brasenia purpurea; B. peltata of Gray) Water-lily family
Flowers - Small, dull purplish, about 1/2 in. across, on stout
footstalks from axils of upper leaves; 3 narrow sepals and
petals; stamens 12 to 18; pistils 4 to 18, forming 1 to 3-seeded
pods. Stem: From submerged rootstock; slender, branching, several
feet long, covered with clear jelly, as are footstalks and lower
leaf surfaces. Leaves: On long petioles attached to center of
underside of leaf, floating or rising, oval to roundish, 2 to 4
in. long, 1 1/2 to 2 in. wide.
Preferred Habitat - Still, rather deep water of ponds and slow
streams.
Flowering Season - All summer.
Distribution - Parts of Asia, Africa, and Australia, Nova Scotia
to Cuba, and westward from California to Puget Sound.
Of this pretty water plant Dr. Abbott says, in "Wasteland
Wanderings": "I gathered a number of floating, delicate leaves,
and endeavored to secure the entire stem also; but this was too
difficult a task for an August afternoon. The under side of the
stem and leaf are purplish brown and were covered with
translucent jelly, embedded in which were millions of what I took
to be insects' eggs. They certainly had that appearance. I was
far more interested to find that, usually, beneath each leaf
there was hiding a little pike. The largest was not two inches in
length. When disturbed, they swam a few inches, and seemed wholly
'at sea' if there was not another leaf near by to afford them
shelter."
