This last feature of adaptationis that on which attention may be speciallyconcentrated here. Mr. Darwin in treatingof orchids has described this part of theirstructure in these words;--" In almost all thespecies, one of the petals (or leaves of theflower) which is properly the upper one, islarger than the others and stands on thelower side of the flower, where it offers alanding-place for insects." * Towards the inneror root end of this leaf (labellurn) is thegland, in some flowers appearing only as aslit, in others forming like a tube, (nectury)which secrets the honey. Just over the entranceto the part where the honey is to befound stands that which secrets the pollenprepared for fertilizing some other flower.So soon as the bee or other insect presses itshead well into the centre of the flower, someof the pollen adheres to it; when the head iswithdrawn, this pollen is borne off to theflower which the bee next visits; and as the* Fertilization,p 6.
