(Habenaria ciliaris) Orchid family
Flowers - Bright yellow or orange, borne in a showy, closely set,
oblong spike, 3 to 6 in. long. The lip of each flower copiously
fringed; the slender spur 1 to 1 1/2 in. long; similar to white
fringed
orchis (q.v.); and between the two, intermediate pale
yellow hybrids may be found. Stem: Slender, leafy, 1 to 2 1/2
feet high. Leaves: Lance-shaped, clasping.
Preferred Habitat - Moist meadows and sandy bogs.
Flowering Season - July-August.
Distribution - Vermont to Florida; Ontario to Texas.
Where this brilliant, beautiful orchid and its lovely white
sister grow together in the bog - which cannot be through a very
wide range, since one is common northward, where the other is
rare, and vice versa - the yellow fringed orchis will be found
blooming a few days later. In general structure the plants
closely resemble each other. Their similar method of enforcing
payment for a sip of nectar concealed in a tube so narrow and
deep none but a sphinx moth or butterfly may drain it all (though
large bumblebees occasionally get some too, from brimming
nectaries) has been described (q.v.), to which the interested
reader is referred. Both these orchids have their sticky discs
projecting unusually far, as if raised on a pedicel - an
arrangement which indicates that they "are to be stuck to the
face or head of some nectar-sucking insect of appropriate size
that visits the flowers," wrote Dr. Asa Gray over forty years
ago. Various species of hawk moths, common in different parts of
our area, of course have tongues of various lengths, and
naturally every visitor does not receive his load of pollen on
the same identical spot. At dusk, when sphinx moths begin their
rounds, it will be noticed that the white and yellow flowers
remain conspicuous long after blossoms of other colors have
melted into the general darkness. Such flowers as cater to these
moths, if they have fragrance, emit it then most strongly, as an
additional attraction. Again, it will be noticed that few such
flowers provide a strong projecting petal-platform for visitors
to alight on; that would be superfluous, since sphinx moths suck
while hovering over a tube, with their wings in exceedingly rapid
motion, just like a hummingbird, for which the larger species are
so often mistaken at twilight. This deep-hued orchid apparently
attracts as many butterflies as sphinx moths, which show a
predilection for the white species.
>From Ontario and the Mississippi eastward, and southward to the
Gulf, the TUBERCLED or SMALL PALE GREEN ORCHIS (H. flava) lifts a
spire of inconspicuous greenish-yellow flowers, more attractive
to the eye of the structural botanist than to the aesthete. It
blooms in moist places, as most orchids do, since water with
which to manufacture nectar enough to fill their deep spurs is a
prime necessity. Orchids have arrived at that pinnacle of
achievement that it is impossible for them to fertilize
themselves. More than that, some are absolutely sterile to their
own pollen when it is applied to their stigmas artificially with
insect aid, however, a single plant has produced over 1,000,700
seeds. No wonder, then, that, as a family, they have adopted the
most marvelous blandishments and mechanism in the whole floral
kingdom to secure the visits of that special insect to which each
is adapted, and, having secured him, to compel him unwittingly to
do their bidding. In the steaming tropical jungles, where
vegetation is luxuriant to the point of suffocation, and where
insect life swarms in mvriads undreamed of here, we can see the
best of reasons for orchids mounting into trees and living on air
to escape strangulation on the ground, and for donning larger and
more gorgeous apparel to attract attention in the fierce
competition for insect trade waged about them. Here, where the
struggle for survival is incomparably easier, we have terrestrial
orchids, small, and quietly clad, for the most part.
Having the gorgeous, exotic air plants of the hothouse in mind,
this little tubercled orchis seems a very poor relation indeed.
In June and July, about a week before the ragged orchis comes
out, we may look for this small, fringeless sister. Its clasping
leaves, which decrease in size as they ascend the stem (not to
shut off the light and rain from the lower ones), are
parallel-veined, elliptic, or, the higher ones, lance-shaped. A
prominent tubercle, or palate, growing upward from the lip,
almost conceals the entrance to the nectary. and makes a side
approach necessary. Why? Usually an insect has free, straight
access down the center of a flower's throat, but here he cannot
have it. A slender tongue must be directed obliquely from above
into the spur, and it will enter the discal groove as a thread
enters the eye of a needle. By this arrangement the tongue must
certainly come in contact with one of the sticky discs to which
an elongated pollen gland is attached. The cement on the disc
hardening even while the visitor sucks, the pollen gland is
therefore drawn out, because firmly attached to his tongue. At
first the pollen mass stands erect on the proboscis; but in the
fraction of a moment which it takes a butterfly to flit to
another blossom, it has bent forward automatically into the exact
position required for it to come in contact with the sticky
stigma of the next tubercled orchis entered, where it will be
broken off. Now we understand the use of the palate. Butterfly
collectors often take specimens with remnants of these pollen
stumps stuck to their tongues. In his classical work "On the
Fertilization of Orchids by Insects," Darwin tells of finding a
mottled rustic butterfly whose proboscis was decorated with
eleven pairs of pollen masses, taken from as many blossoms of the
pyramidal orchis. Have these flowers no mercy on their
long-suffering friends? A bee with some orchid pollen-stumps
attached to its head was once sent to Mr. Frank Cheshire, the
English expert who had just discovered some strange bee diseases.
He was requested to name the malady that had caused so abnormal
an outgrowth on the bee's forehead!
Often found growing in the same bog with the tubercled species is
the RAGGED or FRINGED GREEN ORCHIS (H. lacera), so inconspicuous
we often overlook it unawares. Examine one of the dingy,
greenish-yellow flowers that are set along the stern in a spike
to make all the show in the world possible, each with its
three-parted, spreading lip finely and irregularly cut into
thread-like fringe to hail the passing butterfly, and we shall
see that it, too, has made ingenious provision against the
draining of its spur by a visitor without proper pay for his
entertainment. Even without the gay color that butterflies ever
delight in, these flowers contain so much nectar in their spurs,
neither butterflies nor large bumblebees are long in hunting them
out. In swamps and wet woodland from Nova Scotia to Georgia, and
westward to the Mississippi, the ragged orchis blooms in June or
July.
LARGE YELLOW POND or WATER LILY; COW LILY; SPATTER-DOCK
(Nymphaea advena; Nupisar advena of Gray) Water-lily family

to 24 rays. Leaves: Floating, or some immersed, large, thick,
sometimes a foot long, egg-shaped or oval, with a deep cleft at

Mexico, north to Nova Scotia.
Comparisons were ever odious. Because the yellow water lily has
the misfortune to claim relationship with the sweet-scented white
species (q.v.), must it never receive its just meed of praise?
Hiawatha's canoe, let it be remembered,
"Floated on the river
Like a yellow leaf in autumn,
Like a yellow water-lily."
But even those who admire Longfellow's lines see no beauty in the
golden flower-bowls floating among the large, lustrous, leathery
leaves.
By assuming the functions of petals, the colored sepals advertise
for insects. Beetles, which answer the first summons to a free
lunch, crowd in as the sepals begin to spread. In the center the
star-like disc, already sticky, is revealed, and on it any pollen
they have carried with them from older flowers necessarily rubs
off. At first, or while the stigma is freshly receptive to
pollen, an insect cannot make his entrance except by crawling
over this large, sticky plate. At this time, the anthers being
closed, self-fertilization is impossible. A day or two later,
after the pollen begins to ripen on countless anthers, the flower
is so widely open that visitors have no cause to alight in the
center; anyway, no harm could result if they did,
cross-fertilization having been presumably accomplished. While
beetles (especially Donacia) are ever abundant visitors, it is
likely they do much more harm than good. So eagerly do they gnaw
both petals and stamens, which look like loops of narrow yellow
ribbon within the bowl of an older flower, that, although they
must carry some pollen to younger flowers as they travel on, it
is probable they destroy ten times more than their share. Flies
transport pollen too. The smaller bees (Halictus and Andrena
chiefly) find some nectar secreted on the outer faces of the
stamen-like petals, which they mix with pollen to make their
babies' bread.
The very beautiful native AMERICAN LOTUS (Nelumbo lutea), also
known as WATER CHINKAPIN or WANKAPIN, found locally in Ontario,
the Connecticut River, some lakes, slow streams, and ponds in New
Jersey, southward to Florida, and westward to Michigan and
Illinois, Indian Territory and Louisiana, displays its pale
yellow flowers in July and August. They measure from four to ten
inches across, and suggest a yellow form of the sweet-scented
white water lily; but there are fewer petals, gradually passing
into an indefinite number of stamens. The great round, ribbed
leaves, smooth above, hairy beneath, may be raised high above the
water, immersed or floating. Both leaf and flower stalks contain
several large air canals. The flowers which are female when they
expand far enough for a pollen-laden guest to crawl into the
center, are afterward male, securing cross-fertilization by this
means, just as the yellow pond lily does; only the small bees
must content themselves here with pollen only - a diet that
pleases the destructive beetles and the flies (Syrphidae)
perfectly.
Japanese artists especially have taught us how much of the beauty
of a Nelumbo we should lose if it ripened its decorative
seed-vessel below the surface as the sweet-scented white water
lily does. This flat-topped receptacle, held erect, has its
little round nuts imbedded in pits in its surface, ready to be
picked out by aquatic birds, and distributed by them in their
wanderings. Both seeds and tubers are farinaceous and edible. In
some places it is known the Indians introduced the plant for
food. Professor Charles Goodyear has written an elaborate,
plausible argument, illustrated, with many reproductions of
sculpture, pottery, and mural painting in the civilized world of
the ancients to prove that all decorative ornamental design has
been evolved from the sacred Egyptian lotus (Nelumbo Nelumubo),
still revered throughout the East (q.v.).
