This curious metamorphose of the corol, when the nectaries fall off, seems to shew that the white juices of the corol were before carried to the nectaries, for the purpose of producing honey: because when these nectaries fall off, no more of the white juice is secreted in the corol, but it becomes green, and degenerates into a calyx. See note on Lonicera. Poppy. Many males, many females.
Philos. Botan. No. 150. These vegetable monsters are formed in many ways. 1st. By the multiplication of the petals and the exclusion of the nectaries, as in larkspur. 2d. By the multiplication of the nectaries and exclusion of the petals; as in columbine. 3d.
The plants which produced flowers with the largest glands or nectaries, excreting most nectar, would oftenest be visited by insects, and would oftenest be crossed; and so in the long-run would gain the upper hand and form a local variety.
Its threshold must bear its own peculiar welcome to its insect, or perhaps to its humming-bird friend, or counterpart; its nectaries must both tempt and reward his coming, and its petals assist his comfortable tarrying.
In the Apocynum Androsaemifolium, one kind of Dog's bane, the anthers converge over the nectaries, which consist of five glandular oval corpuscles surrounding the germ; and at the same time admit air to the nectaries at the interstice between each anther.
What a variety of treasures were spread out before me: larkspurs, from whose pointed nectaries I might weave "circles without end," varying the pattern of each by alternate proportions of blue, and pink, and white. There were foxgloves to be examined, whose depths were so mysteriously freckled; there were clusters of cowslips, and moss-pinks to be counted.
Wallace, nine and a quarter inches in length, probably to enable their owner to probe the deep nectaries of certain orchids.
On the other hand swiftness of wing has been acquired by hawks and swallows to pursue their prey; and a proboscis of admirable structure has been acquired by the bee, the moth, and the humming bird, for the purpose of plundering the nectaries of flowers.
Flowers fertilised by humming-birds. By insects. Provision in some flowers to prevent insects, not adapted for carrying the pollen, from obtaining access to the nectaries. Stories about wasps. Humming-birds bathing. Singular myriapods. Ascent of Pena Blanca. Tapirs and jaguars. Summit of Pena Blanca.
To assume thus much requires no inordinate stretch of faith; and thus much being assumed, it is seen at once that the hive bee, requiring for its cells only about half as much wax as the humble bee does, and consequently only about half as much honey for the secretion of the requisite wax, would, in a struggle for existence, leave the humble bee so little chance that in all probability the two species would nowhere coexist, were it not for the special resource derived by the humble bee from possession of a trunk long enough to enter the nectaries of certain flowers, which the shorter trunk of the hive bee is unable to tap.
