Schoenocaulon is a North American genus of perennial herbaceous flowering plants, ranging from the southern United States to Peru.[3] It is a member of the Melanthiaceae, according to the APG III classification system, and is placed in the tribe Melanthieae. Unlike other genera in the tribe, the flowers are arranged in a spike; depending on the species the flower stalks for each flower are either very short or completely absent.[4] Feathershank is a common name,[5] the medicinally used S. officinale is called Sabadilla (pronunciation: /sab-uh-dil-uh/, IPA: /ˌsæb əˈdɪl ə/).
Plants generally grow in chaparral, oak, or pine forests. Grazing has narrowed the natural ranges of some species to only steep, rocky terrain.[6] Mexico is the center of Schoenocaulon diversity, with 22 endemic species - some with distributions limited to single mountain ranges.[4] The two species with the widest distributions, S. yucatanense (sometimes treated as part of S. ghiesbreghtii) and S. officinale (sabadilla), may have been spread by pre-Columbians who used the seeds as pesticides.[4]
The petal and sepal color varies by species, with some shade of green being most common, but with maroon, cream, and bright red also represented.[4]
