Range Extent5000-200,000 square km (about 2000-80,000 square miles)
Rank Reasons
Calochortus amoenus is endemic to central California in the Sierra Nevada foothills, however, there is uncertainty over whether the range may extend beyond this.
Range Extent Comments
Endemic to California. Hickman (1993) lists the bioregional distribution as the central and southern Sierra Nevada Foothills. The Consortium of California Herbaria (as of March 2007) has ten accession records from four counties not in this distribution: Glenn, Lake, Alameda, and San Luis Obispo; all but the collection from San Luis Obispo were collected before Hickman was published so it is not clear why these are left out of that distribution. The majority of the collections (128) are from the range described in Hickman.
Occurrences Comments
The number of distinct occurrences is unknown, but the Consortium of California Herbaria database contains 138 accession records for Calochortus amoenus; 15 of these have been collected since 1970.
