PLATE Onagra cruciata. leaf from young rosette ; 2, leaf from lower part of mature rosette ; 3, leaf from upper part ofmature rosette; 4, stem-leaf; 5, rosette five months old ; 6, rosette two months old ; 7, rosettenearly five months old, with narrower leaves. 1 to 4, half natural size; 5 to 7, natural size. MUTANTS AND HYBRIDS OF THE OENOTHERAS. 15 undulate, obtuse or merely acutish at the apex, each rather graduallynarrowed into a petiole. (PI. X, fig. 6.) Seedlings five months old.—Rosettes not dense; leaves glabrous ornearly so, except the ciliate margins; blades spatulate, some of themnarrowly so, the larger ones 2 to cm. wide, shallowly repand-dentic-ulate, mostly acute, as long as the petioles or longer. (PL III, fig. 2.) Mature rosette.—Leaves conspicuously elongated, obscurely fine-pubesdent, the larger ones about 26 cm. long, 25 to 30 mm. wide;blades narrowly spatulate, repand-dentate, more distantly so and withprominent teeth near the base, petioles relatively slender.
