So very many flowers especially adapted to the bumblebee are in
bloom when the cymes of the waterleaf uncoil, like the borages,
from their immature roll, that some special inducement to attract
this benefactor were surely needed. In high altitudes the
clusters became deeper hued; but much as the more specialized
bees love color, food appeals to them far more. Accordingly the
five lobes of each little flower stand erect to increase the
difficulty a short-tongued insect would have to drain its
precious stores; the stamens are provided with hairs for the same
reason; and even the calyx is bristly, to discourage crawling
ants, the worst pilferers out. By these precautions against
theft, plenty of nectar remains for the large bees. To prevent
self-fertilization, pollen is shed on visitors, which remove it
from a newly opened flower before the stigmas become receptive to
any; but in any case these are elevated in maturity above the
anthers, well out of harm's way.
