In 1841, a plant was discovered  in the Shasta Mountains region in California by to J. D. Brackenbridge. The first published description was made in 1853 by J. Torrey who dedicated it to his friend, botanist Dr. W. Darlington.

Distribution

The plant is found naturally in Oregon and California, on an axis running from Roseburg in Santa Rosa and a radius of 80 km to the west and east of the axis. 

Biotope

The diversity of locations and altitudes at which grows Darlingtonia is such that despite an overall cool and humid climate, the temperature differences are important. The annual rainfall are highly variable, from 100 cm to 200 cm according to the states. The soil called serpentine (hydrated magnesium silicate) display some large populations of plants and a flow of cold water is going under the surface, maintaining cool temperatures in the root level. In some environments, Sphagnum, Drosera, Pinguicula, Cypripedium ... grow with the Cobra Lily.

Description

Perennial herbaceous plant, 40-100 cm high. The green leaves, are radical and cone-shaped. The upper ends in a dome, with an appendix mustache-shapped. The opening of the pitcher is located under the hood.

Traps are formed by leaves with suggestive forms that capture prey. They arise on "mustaches" that are looking like runways. The insects entering in the pitchers, attracted by the nectar, and slides on the bottom, where it can no longer come up and be digested by bacteria only.

The prey are mostly composed of insects: Coleoptera, Diptera ...

The single flower is supported by scapes, have brown petals and green sepals.
