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.{{cite journal| last = Zomlefer| first = WB|author2=WS Judd | title = Resurrection of Segregates of the Polyphyletic Genus Zigadenus s.l.

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.{{cite journal|

Species include:
Different botanists and sources recognize different numbers of distinct species. The Flora of North America and USDA recognize two: Stenanthium gramineum and Stenanthium occidentale.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=131349 eFloras.org: Stenanthium treatment] . accessed 6.26.2017.[http://plants.usda.gov/plant-profile?symbol=STENA2 USDA: Stenanthium treatment]. accessed 6.26.2017.
