History

Calochortus aureus was published by Sereno Watson in 1873,[6] based on material collected by Ellen Powell Thompson in 1872 in the vicinity of Kanab, Utah, during the US Topographical and Geological Survey of the Colorado River (led by John Wesley Powell). Her specimen is deposited at the United States National Herbarium (US). It was later reclassified as Calochortus nuttallii var. aureus by Ownbey, but is now recognized as a full species, as originally described.[7]
