Stanleya pinnata
Stanleya pinnata is a species of flowering plant in the family Brassicaceae known as desert prince's-plume.[2] It is a perennial herb or shrub native to North America. DistributionThe plant is native to the western Great Plains and western North America.[3] It occurs in many types of open habitat, including deserts, chaparral, foothills, rocky cliffs, sagebrush, and prairie. It prefers alkali- and gypsum-rich soils.[4] DescriptionStanleya pinnata is a perennial herb or shrub producing several erect stems reaching up to about 1.5 metres (4+11⁄12 ft) in maximum height. The stems are unbranched,[5] hairless, often waxy in texture, and have woody bases. The leaves have fleshy blades up to 15 centimeters long by 5 wide which are divided into several long, narrow lobes. The blades are borne on petioles. The top of the stem is occupied by a long inflorescence which is a dense raceme of many flowers. Each flower has four narrow yellowish sepals which open to reveal four bright yellow petals[5] each up to 2 cm long. The stamens protruding from the flower's center may approach 3 cm in length. The fruit is a curving, wormlike silique up to 8 cm long. UsesIt has been used as a Native American traditional medicinal plant and food source, including by the Hopi, Zuni, Paiute, Navajo, Kawaiisu, and Tewa peoples.[6] EcologyIt is a larval host to both Becker's white and checkered white caterpillars.[7] Some of the plant's amino acids use selenium from the soil in place of sulfur, making it highly toxic to animals.[5] References
