Triantha occidentalis, the western false asphodel, is a species of flowering plant in the family Tofieldiaceae. It is found in the Pacific Northwest.[2]
Triantha occidentalis was described by Sereno Watson in 1879 as Tofieldia occidentalis, and reassigned to Triantha by R. R. Gates in 1918.[3][4] The carnivorous behavior of the plant was discovered in 2021 by a group of scientists from the University of British Columbia and the University of Wisconsin–Madison.[5]
Triantha occidentalis is a carnivorous plant; the stem is covered in a sticky substance, and has tiny hairs that produce a digestive enzyme, a phosphatase. The sticky substance is able to trap small insects, which are digested by the enzyme from the hairs, allowing the plant to absorb their nutrients.[6][5] Of note is that the sticky stem is only able to entrap smaller insects, such as midges, and does not affect larger insects like bees or butterflies that may play a role in pollination.[5][7] The plant is considered to be unique in this method of carnivory.[6][7]
