Stenanthium is a North American genus of flowering plants in the family Melanthiaceae, tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in number of changes to placements within this tribe. Three species were removed from the genus to Anticlea and two or three (depending on whether S. leimanthoides is maintained as a separate species) added from Zigadenus sensu lato, the deathcamases.[2] (See also Phylogeny of Melanthieae.) Members of Stenanthium, as currently circumscribed, may also be distinguished from other deathcamases by having a slender cylindrical bulb and the lack of sarcotesta on its brown seeds. They occur in the eastern and south-central United States.[3][2] Featherbells is a common for plants in this genus.[4]
- Species
As of August 2013, the World Checklist of Selected Plant Families recognized three species, treating S. leimanthoides as a synonym of S. densum.[5] Other sources recognize S. lemanthoides as a separate species.[6][7]
- Stenanthium densum (Desr.) Zomlefer & Judd – Osceola's plume - southeastern United States from Texas to Virginia
- Stenanthium diffusum Wofford - Tennessee
- Stenanthium gramineum (Ker Gawl.) Morong – Eastern featherbells - eastern + south-central United States from eastern Texas to Florida north to Michigan and Connecticut
- Stenanthium leimanthoides (A.Gray) Zomlefer & Judd – Pine Barren deathcamas - eastern + south-central United States from eastern Texas to Florida north to New York
