The genus/species Darlingtonia, commonly known as the cobra plant/lily or the California pitcher plant, is a part of the same family as Sarracenia, but is native only to parts of the Pacific Northwest. It gets its name from the curved, hooded traps and their appendages, which hang downward in the shaped of a forked tongue. The plant employs a passive pitcher to capture its prey. Unlike its American pitcher plant cousins, the pitcher of a cobra plant has downward pointing hairs inside, thus once an insect enters it only goes one way. And, if you follow the pitcher from the bottom of the plant, the traps twist to face 180 degrees from the stalk's original direction.
