Discussion

Forest openings and meadows at montane and subalpine elevations. Flowering Jun–Aug. 800–1800m. Casc. WA; north to British Columbia. Native.

Similar to its presumed close relative E. elegans, this species is best identified by its linear, very narrow (less than 0.8 mm) filaments. Its flowers also tend to be more outward-facing than E. elegans and our other species, which are usually nodding. Like E. grandiflorum, this lily is also found emerging from melting snow in montane and subalpine meadows.

Openings in dry woods, occasionally fields or meadows. Flowering Mar–May. 200–1800m. Casc, Sisk. CA. Native.
