ORCHIDACE^—IRIDACE^ 413 is at the two ends of the horse-shoe, and by one or other of these (Fig. 336, e) the insect generally escapes, in doing which, however, it almost inevitably comes in contact with, and carries off some of the pollen from the corre- sponding anther.

In a Trinidad species, Coryan- thes macrantha,^ the basal part of the lip forms bucket, which secretes a copious fluid which wets the wings of the bees, and by rendering them temporarily incapable of flight, compels them to creep out through the small passages close to the anther and stigma, thus securing, though by difterent means, the object which in Cypripedium is efi"ected by the inflected margins of the Fig. 335.
