Triantha occidentalis is a monocotyledonous plant belonging to the Tofieldiaceae family. It grows in nutrient-poor marshy and sphagnum areas on the west coast of North America, from California to Alaska, often coexisting with Darlingtonia californica. The plant has a rosette of 2-4 leaves at its base, the outermost being the most elongated and 0.5 to 1 cm wide in adult specimens. When in bloom, it produces a scape up to 80 cm tall, ending in flowers in clusters of three, hence the name Triantha. The floral scape is the part dedicated to digesting and capturing insects. It features a series of sticky hairs that trap small insects, mostly midges. Finally, the fruits are capsules containing reddish seeds, about 1 mm long, enclosed in a whitish cuticle.
