Taxonomic CommentsThe genus name "Cacalia" was used for a group of plants now generally recognized as belonging to eight genera, and has been variously used for differing portions of that group. In 1998, the Committee for Spermatophyta published (Taxon 47: 444) its decision to reject this name nomenclaturally, in order to avoid confusion. Thus, all plants formerly called Cacalia must now be classified into other genera. LEM 3Jun98.

Rank ReasonsArnoglossum atriplicifolium occurs in eastern North America, in the United States from New York, south to the Florida Panhandle, and west to Nebraska, Kansas, and Oklahoma. There are over 1000 occurrences rangewide, threats include fragmentation and loss of habitat as a result of residential development and urbanization, competition from invasive exotic plants, and herbivory by deer.
Range Extent CommentsArnoglossum atriplicifolium occurs in eastern North America, in the United States from New York, south to the Florida Panhandle, and west to Nebraska, Kansas, and Oklahoma. Range extent was estimated to be 2.0 million square kilometers, using herbarium specimens and photo-based observations documented between 1992 and 2023 (Flora of North America Editorial Committee 2006, GBIF 2023, iNaturalist 2023, Weakley and Southeastern Flora Team 2023).
Occurrences CommentsBased on herbarium records and photo-based observations documented between 1992 and 2023, and anecdotal evidence, there are over 1000 occurrences rangewide (GBIF 2023, iNaturalist 2023).
Threat Impact CommentsThreats to Arnoglossum atriplicifolium include fragmentation and loss of habitat as a result of residential development and urbanization, competition from invasive exotic plants, and herbivory by deer (Johnson 2023).
