But in the case of a Cypriped there is no such substance, the adhesive side of the pollen itself is turned outward, and it clings to any intruding substance. But this is the fertilizing part. Therefore, an insect which by chance displaces the pollen mass carries it off, as one may say, the wrong side up.
The reason lies in that archaic character of the Cypriped which Darwin pointed out. Its time has passed Nature is improving it off the face of the earth. A gradual change of circumstances makes it more and more difficult for this primitive form of orchid to exist, and, conscious of the fate impending, it gratefully accepts our help. One cause of extermination is easily grasped.
