Wild Flowers: An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors
Blanchan, Neltje
Wild flowers -- North America
Much taller than the preceding dwarfs is the COMMON PRIVET
ANDROMEDA found in swamps and low ground from New England to the
Gulf and in the southwest (Xolisma ligustrina). Whoever has seen
the privet almost universally grown in hedges is familiar with
the general aspect of this much-branched shrub. Most farmers'
boys know the Andromeda's mock May-apple, a hollow, stringy
growth of insect origin, which they are not likely to confuse
with the pulpy, juicy apple found on the closely related azaleas
(q.v.). Abundant terminal spike-like or branched clusters of
white, globular, four or five parted flowers in close array,
attract quantities of bees from the end of May to early July,
notwithstanding each individual flower measures barely an eighth
of an inch across. We have seen the fine hair-triggers which
other members of this same family, the beautiful pink laurels
(q.v.), have set to be sprung by an incoming visitor. Now this
Andromeda, and similarly several of its immediate kin, have a
quite different, but equally effective, method of throwing pollen
on its friends who come to call. When one of the little banded
bees clings, as he must, to the tiny flower scarce half his size,
thrusting his tongue obliquely through the globe's narrow opening
to reach the nectar, suddenly a shower of pollen is inhospitably
thrown upon him from within. In probing between the ring of
anthers (that are pressed against the style by the S-shaped
curvature of the filaments so as to retain the pollen), he needs
must displace some of them and release the vitalizing dust
through the large terminal pores in the anther-sacs. Is he
discouraged by such rough treatment? Not at all. Off he flies to
another Andromeda blossom, and leaves some of the dust with which
he is powdered on the sticky stigma that impedes his entrance,
before precipitating a fresh shower as he sips another reward.
The straight column-like pistil, stigmatic on its tip only,
allows the flower's own pollen to slide harmlessly down its
sides. How exquisite are the most minute adjustments of floral
mechanism! Is it possible for one to remain an agnostic after the
evidences even the flowers show us of infinite wisdom and love?
