Stenanthium is a North American genus of flowering plants in the tribe Melanthieae of the family Melanthiaceae.

Featherbells is a common name for plants in this genus.[2]

Taxonomy

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.[3] (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.[4][3]

Species

Species include:

Different botanists-sources recognize a different number of distinct species. The Flora of North America and USDA recognize two, Stenanthium gramineum and Stenanthium occidentale. [10] [11] Some sources recognize S. lemanthoides as a separate species.[12][13] The World Checklist of Selected Plant Families recognized three species in 2013, treating S. leimanthoides as a synonym of S. densum.[14]
