Sometimes this is done, as in thelarkspur, the violet, and the garden nasturtium, byputting the honey at the bottom of a long spur orblind sac ; and if you bite off the end of the sac inthe nasturtium you will find a very appreciable quan-tity of nectar stored up in it. But most highly spe-cialised flowers have hit upon a simpler plan, whichis to run all their petals together at the bottom into atube, so long that no useless insect can rob the honeywithout fertilising

In pinks andtheir allies we see some rude approach to this modeof growth ; for there each petal has a long claw (as itis called), bearing the expanded part at the end ; andthese claws when firmly pressed together by the calyxpractically form a tube in five pieces : but in the per-.
