Taxonomic Comments
Taxon has been recognized in the past at the infraspecific level (e.g., Munz) as Erythronium grandiflorum ssp. pusaterii. According to John Kartesz (e-mail to Larry Morse, 3Jun99), this name honors Samuel J. Pusateri, and therefore is correctly spelled 'pusaterii' rather than 'pusateri'.

Rank Reasons
Erythronium pusaterii is endemic to the Kaweah and Tulare River watersheds in the southern Sierra Nevada in California. The plant is known from eight occurrences, all adequately protected within the Sequoia National Forest and Sequoia-Kings Canyon National Park. Threats are also diminished by the inaccessibility of the sites.
Range Extent Comments
Endemic to the Kaweah and Tule River watersheds in Tulare County, California, in the southern Sierra Nevada Mountains (Shevock, 1990). Area of the minimum convex polygon, range extent, is 108 sq km.
Occurrences Comments
Known from eight occurrences (CNDDB 2013).
Threat Impact Comments
Most occurrences are relatively inaccessible (Skinner, 1997). In some cases, trampling may be a minor threat (Bittman 1998).
