First as to the facts. The leaves of maturo rhizomes - the true Darlingtonia leaves - nro each twisted one half way round whatever the length, whether one half inch, or over three feet. All the leaves on one plant turn one way, but exactly half (according to repeated counts by Mrs. Austin and myself, ) have leaves turning one way and half the other. The four leaves of the season rise successively to different elevations, the last in time, to the highest place. Each turns half-round and holds out its flaunting lures into space in a direction radiating from the center or axis of the plant. The reason for this twisting of the petiole must be to further the design - the malicious animus of the whole plant's history, to favor the catching of insects coming from all quarters.
The less crafty-related Sarracenia and the infant Darlingtonia leaf depend on gravitation mainly, for their food, and their mouths border-ed indeed with retrorse hairs open upward. The full-grown, full-armed Darlingtonia, with its added attractions of gay colors, fragrant odors and delicious sweets, best compasses the wholesale capture of insects necessaiy to satiate its rapacity by decoying them into a brilliantly lighted chamber, over the ceiling of which are spread a net-work of honeyed path-ways, bordered, however, and ultimately shut out by hedges of short stiff hairs that topple the victim from his footing. A high rim prevents return by the aperture. A long portion of the inner side of the tube, commencing just on a levelwith the edge of the orifice, is smooth as glass, so vainly the poor victim stretches his legs for rescuing aids to stay his descent. About half way down, long stiff declined hairs begin to be met with, which give away easily from above but close up behind and with multiplied numbers, as the struggling victim nears the goal, pushes him down to the rising flood, and crowds him beneath the silent, foetid decomposing waters of oblivion.
