The double flowers become monsters by the multiplication of their petals or nectaries.

Nature has in many flowers used a wonderful apparatus to guard the nectary, or honey-gland, from insects.

In Aconitum, monkshood, the nectaries stand upright like two horns covered with a hood, which abounds with such acrid matter that no insects penetrate it.

In Helleborus, hellebore, the many nectaries are placed in a circle, like little pitchers, and add much to the beauty of the flower.

In the Columbine, Aquilegia, the nectary is imagined to be like the neck and body of a bird, and the two petals standing upon each side to represent wings; whence its name of columbine, as if resembling a nest of young pigeons fluttering whilst their parent feeds them.

The importance of the nectary in the economy of vegetation is explained at large in the notes on part the first.

Besides these there is a curious contrivance attending the Ophrys, commonly called the Bee-orchis, and the Fly-orchis, with some kinds of the Delphinium, called Bee-larkspurs, to preserve their honey; in these the nectary and petals resemble in form and colour the insects, which plunder them: and thus it may be supposed, they often escape these hourly robbers, by having the appearance of being pre-occupied.

After impregnation the flower undergoes a remarkable change, the nectaries drop off, but the white corol remains, and gradually becomes quite green.

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.

The nectary of the Tropaeolum, garden nasturtion, is a coloured horn growing from the calyx.

The nectary of this plant grows from what is supposed to be the calyx; but this supposed calyx is coloured; and perhaps, from this circumstance of its bearing the nectary, should rather be esteemed a part of the coral.

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.

Not only her character, but her beauty, became another thing under all this largess; one remembered the very Persian rose, in looking at her, and thought of gardens amid whose clouds of rich perfume the nightingales sang all night long; her manner, too, became strangely gracious, and a sweetness lingered after her presence, delicate and fine as the drop of honey in some flower's nectary.

The humming-bird alone can reach the bottom of the nectary of the honeysuckle; but even here the instinct of the bee is seen.

For this purpose it is that most plants lay themselves out to secure the attention of only two or three varieties among their insect allies, while they make their nectaries either too deep or too shallow for the convenience of all other kinds.
