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

Wild flowers -- North America
Another herbaceous perennial once counted a spiraea is the common
INDIAN PHYSIC or BOWMAN'S-ROOT (Porteranthus trifoliatus -
Gillensia trifoliata of Gray) found blooming in the rich woods
during June and July from western New York southward and
westward. Two to four feet high, it displays its very loose,
pretty clusters of white or pale pink flowers, comparatively few
in the whole panicle, each blossom measuring about a half inch
across and borne on a slender pedicel. A tubular, 5-toothed calyx
has the long slender petals inserted within. Owing to the depth
and narrowness of the tube, the small, long-tongued bees cannot
reach the nectar without dusting their heads with pollen from the
anthers inserted in a ring around the entrance or leaving some on
the stigmas of other blossoms. Later, the five carpels make as
many hairy, awl-tipped little pods within the reddish cup. The
leaves may be compounded of three oblong or ovate, saw-edged
leaflets, or merely three-lobed, and with small stipules at their
base.
WILD RED RASPBERRY
(Rubus strigosus) Rose family
Flowers - White, about 1/2 in. across, on slender, bristly
pedicels, in a loose cluster. Calyx deeply 5-parted, persistent
in fruit; 5 erect, short-lived petals, about the length of the
sepals; stamens numerous; carpels numerous, inserted on a convex
spongy receptacle, and ripening into drupelets. Stem: 3 to 6 ft.
high, shrubby, densely covered with bristles; older, woody stems
with rigid, hooked prickles. Leaves: Compounded of 3 to 5 ovate,
pointed, and irregularly saw-edged leaflets, downy beneath, on
bristly petioles. Fruit: A light red, watery, tender,
high-flavored, edible berry; ripe July-September.
Preferred Habitat - Dry soil, rocky hillsides, fence-rows,
hedges.
Flowering Season - May-July.
Distribution - Labrador to North Carolina, also in Rocky Mountain
region.
Who but the bees and such small visitors care about the raspberry
blossoms? Notwithstanding the nectar secreted in a fleshy ring
for their benefit, comparatively few insects enter the flowers,
whose small, erect petals imply no hospitable welcome.
Occasionally a visitor laden with pollen from another plant
alights in the center of a blossom, and leaves some on the
stigmas in bending his head down between them and the stamens to
reach the refreshment; but inasmuch as the erect petals allow no
room for the stamens to spread out and away from the stigmas, it
follows that self-fertilization very commonly occurs.
