“All the Kalmias resort to a most ingenious device for compelling insect
visitors to carry their pollen from blossom to blossom. A newly opened
flower has its stigma erected where the incoming bee must leave on its
sticky surface the four minute orange-like grains carried from the
anther of another flower on the hairy underside of her body. Now, each
anther is tucked away in one of the ten little pockets of the
saucer-shaped blossom and the elastic filaments are strained upward like
a bow. After hovering above the nectary, the bee has only to descend
towards it, when her leg, touching against one of the hair-triggers of
the spring trap, pop! goes the little anther-gun, discharging pollen
from its bores as it flies upward. So delicately is the mechanism
adjusted, the slightest jar or rough handling releases the anthers; but,
on the other hand, should insects be excluded by a net stretched over
the plant, the flowers will fall off and wither without firing off their
pollen-charged guns. At least this is true in the great majority of
tests. As in the case of hot-house flowers, no fertile seed is set when
nets keep away the laurel’s benefactors.”
Many of our readers reside near the home of the Mountain Laurel and can
examine the interesting features of this beautiful plant in Nature’s own
garden. Those that do this will be well repaid.
Violets stir and arbutus waits,
Claytonia’s rosy bells unfold;
Dandelion through the meadow makes
A royal road, with seals of gold.

HOPS.
(_Humulus lupulus L._)
“A land of hops and poppy-mingled fields.”
—Tennyson: Aylmer’s Field.
The hop plant is a creeping perennial with several stems or branches
attaining a length of fifteen to twenty-five feet. It has numerous
opposite three to five lobed, palmately veined, coarsely toothed leaves
with long leaf stalks (petioles). Flowers unisexual, that is staminate
and pistillate flowers separate, either on separate plants (dioecious)
or upon different branches of the same plant (monoecious). Flowers
insignificant in loose, drooping axillary panicles. Fruit a cone-like
catkin usually designated a strobile.
