Stenanthium leimanthoides

Stenanthium leimanthoides is a poisonous monocot wildflower native to acid montane areas of the eastern United States. It is either treated as a separate species to Stenanthium densum[3] or as a synonym of that species.[4] A common name is pine barren deathcamas.

Synonyms[2]
  • Amianthium leimanthoides A.Gray
  • Zigadenus leimanthoides (A.Gray) A.Gray]

Within the family Melanthiaceae, it is placed in the tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in substantial rearrangement of the species in this tribe, many being moved to different genera. S. leimanthoides was previously placed in Zigadenus as Z. leimanthoides, and will be found under this name in older sources.[5]

It is native to the southernmost United States, more inland than S. densum, largely in the Appalachian Mountains. The plants endanger livestock, particularly in the West.[6]
