During the second year the creeping, rhizo-matic character of the plant is manifested; also, it increases rapidly in size. The whorl of leaves now produced, from one-half an inch to several inches beyond the first whorl, are long and large, two to three inches long by half an inch wide, the whole striated with longitudinal veins, and colored with yellow and crimson. Often, too, the other kind of leaves make their appearance, forming one or more of the first members of the whorl. So very different are they at the very beginning that it seems impossible that both forms should be found on the same plant. They may be larger or smaller than the infantile form (often but half an inch long, ) but still they will be perfect types of the true Darlingtonia leaf - the twisted petiole, the swelling, light-admitting hood, the small, round aperture facing downward, the enormous, depending, curling, flaming, and, in the season, honey-smeared, two-parted lamina or true leaf.

The fourth year's leaves and all subsequent are all of the vaulted, big-mustached form - the plant is of age, is mature; but occasionally on offsets and runners from weak plants at any age, the infant form of leaf is found, but no graded, transitional stages have yet been detected, though much research has been applied in this particular direction, as bearing upon the popular theory of evolution. The linear, strict petiole, with upturned mouth and long, naked, midrib, always accompanies the infant form, while the adult leaf is never deficient in the least characteristic feature of its wondrous organism.

I should have noted before, the manner of vernation or budding. In the bud, the petioles of both kinds of leaves first take form and extension. The midrib of the infant is but a minute, subulate spur; the future mustache of the adult form is a pair of involuted, close-rolled awl-shaped horns, not unlike those waxen pilose appendages which the incipient dandy sometimes displays beneath his nose.
