Wild Flowers: An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors

Wild flowers -- North America
Graceful in gesture, with delicate, fernlike leaves and
anise-scented roots that children, like rabbits, delight to
nibble, the sweet cicely attracts attention by its fragrance,
however insignificant its flowers. In wooded places, such as it
prefers to dwell in, white blossoms, which are far more
noticeable in a dim light than colored ones, and finely cut
leaves that can best withstand the drip from trees, abound. These
white umbels bear a large proportion of male, or pollen-bearing,
florets to the number of hermaphrodite, or two-sexed, florets;
but as the latter mature their pollen before their stigmas become
susceptible to it, self-fertilization is well guarded against,
and cross-fertilization is effected with the help of as many
flies as small bees, which come in numbers to lick up the nectar
so freely exposed in consideration of their short tongues. We
have to thank these little creatures for the long, slender seeds,
armed with short bristles along the ribs, that they may snatch
rides on our garments, together with the beggar-ticks, burdock,
cleavers, and other vagabond colonists in search of unoccupied
ground. Be sure you know the difference between sweet cicely and
the poisonous water hemlock before tasting the former's spicy
root.
Was there no more important genus - containing, if possible, red,
white, and blue flowers - to have named in honor of the Father of
his Country?
Another member of the Carrot family, the SANICLE or BLACK
SNAKEROOT (Sanicula Marylandica), found blooming from May to July
in such rich, moist woodlands and shrubbery as the sweet cicely
prefers, lifts spreading, two to four rayed umbels of
insignificant-looking but interesting little greenish-white
florets. At first the tips of the five petals are tucked into the
center of each little flower; underneath them the stamens are now
imprisoned while any danger of self-fertilizing the stigma
remains. The few hermaphrodite florets have their styles
protruding from the start, and incoming insects leave pollen
brought from staminate florets on the early-maturing stigmas.
After cross-fertilization has been effected, it is the pistil's
turn to keep out of the way, and give the imprisoned stamens a
chance: the styles curve until the stigmas are pressed against
the sides of the ovary, that not a grain of pollen may touch
them; the petals spread and release the stamens; but so great is
the flower's zeal not to be fertilized with its own pollen that
it sometimes holds the anthers tightly between the petals until
all the vitalizing dust has been shed! Around the hermaphrodite
florets are a large number of male florets in each hemispheric
cluster. Hooked bristles and slender, curved styles protrude from
the little burr-like seeds, that any creature passing by may give
them a lift to fresh colonizing land! The firm bluish-green
leaves, palmately divided into from five to seven oblong,
irregularly saw-edged segments, the upper leaves seated on the
