Sarraceniaceae are a family of pitcher plants, belonging to order Ericales.

Darlingtonia californica —also called the California pitcher plant, the Oregon pitcher plant, cobra lily or cobra plant—is a species of carnivorous plant in the new world pitcher plant family, Sarraceniaceae. It is the sole species within its monotypic genus, Darlingtonia. The cobra lily is native to Northern California and Oregon, in the western United States, where the climate—while typically thought of as cool and humid—may be quite arid for many months of the year, more so than many carnivorous or pitcher plant genera could feasibly survive. However, the cobra lily has evolved into life along the West Coast and in the lower Pacific Northwest through its carnivorous adaptions, where it may be found near bogs, vernal pools, on forested rocky slopes, creeks, or near seeps with cold running water, usually on serpentine soils. It has even been observed growing in drainage ditches or on the sides of roads. Despite being fairly commonly cultivated, Darlingtonia is designated as uncommon due to its rarity in the field.
