Abstract

It is well known that Darlingtonia californica has two types of carnivorous leaves (Goebel 1891; Lloyd 1942). The juvenile carnivorous leaves consist of a long tube with a narrow, tongue-like extension that quite often curves down toward if not to the ground (Front Cover). The adult carnivorous leaves are a hooded tube with a fish tail or mustache-like extension. Large juvenile leaves can also be found on stolons or underground runners from adult plants. Horizontal small adult leaves can be found on juvenile plants. Developmentally, the juvenile leaves are not just simplified adult leaves (Franck 1976). Each type of leaf is adapted to a different set of prey.
