Taxonomic Comments
Erythronium quinaultense was described in 2001, and was discovered via molecular analysis to be of hybrid origin with parents E. revolutum and E. montanum (Allen 2001). E. quinaultense is morphologically intermediate between E. revolutum and E. montanum (Allen 2001). "In both elevation and geographic range it is distinct from its parent taxa" (Allen 2001).

Rank Reasons
Erythronium quinaultense is endemic to the southwestern Olympic Peninsula in Washington State. There are four occurrences are known. Threats include invasive plants.
Range Extent Comments
Erythronium quinaultense is restricted to a small geographic area of two adjacent ridge systems in the southwestern Olympic Mountains, Washington State (Allen 2001).
Occurrences Comments
There are four occurrences according to the Washington Nevada Natural Heritage Program (NatureServe Network Database as of December 2020).
Threat Impact Comments
Erythronium quinaultense habitat is being impacted by invasive plants at eight sites in Olympic National Forest (USFS 2008). Other threats include roads, logging, and trampling by elk.
