It must not be supposed that all the species gothrough as many transformations as P. crassifolium, thoughall of them show many variations in leaf shape. In P. crassi-folimn, var. u7iifoliolatum, the deflexed leaf-form passes byimperceptible gradations into the final stage, and there is notrifoliate stage. The later deflexed leaves become, in this case,very coarsely toothed, incised, and expanded at the tips, beforeadopting their final form. If the
