Pig. 325. pressed against the upper, so as to leave only a chink or rictiis between them, the corolla is said to be personate or mask-like (persona, a mask), as in Frogsmouth (fig. 325), Snapdragon, and some other Scrophu- lariacese, and the projecting portion, p, of the lower lip is called the palate. In some corollas the two lips become hollowed out in a remarkable manner, as in Calceolaria, assuming a slipper-like appearance, similar to what occurs in the labellum of some Orchids, as Cypripedium. The cakeolate (calceolus, a slipper) corolla of Calceolaria may be considered as consisting of two slipper-like lips. When a tubular corolla is split in such a way as to form a strap-like process on one side with several tooth-like projections at its apex, it becomes ligulate {ligula, a little tongue), or strap-shaped (fig. 326). This corolla occurs in many composite plants, as in the florets of Dandelion, Daisy, and Chicory. The number of divisions at the apex indicates the number of united petals, some of which, however, may be abortive. Occasionally some of the petals become more united than others, Kg. 326. Fig. 322.
