Bogs, streams, and springs. Flowering Jun–Aug. 100– 1500m. Sisk. CA. Native.

Vollmer’s lily is quite variable, and phenotypic expression is highly dependent on environment and soils. Around the geographic edges of this range, identification becomes more difficult, and ssp. vollmeri intergrades with other subspecies of pardalinum along all its boundaries to produce morphologically jumbled intermediates. Even within the core range of the subspecies, plants in deep shade generally have scattered, wider leaves that much resemble ssp. pardalinum. Like most L. pardalinum, Vollmer’s lily is pollinated in Oregon by pale and western tiger swallowtails and also visited by rufous hummingbirds.

Wet thickets, meadows, streams among conifers. Flowering Jul–Aug. 1000–2000m. Sisk. CA. Native.

Subspecies wigginsii is a Klamath Mountains endemic that occurs widely along the county boundary between Del Norte and Siskiyou counties, California, and east through southeastern Josephine County, Oregon, to Mount Ashland in Jackson County (Ballantyne 1983). It intergrades with ssp. vollmeri near Grayback Mt. in Josephine County, and reaches its purest, most consistent expression high on Mt. Ashland in Jackson County. The solid orange flowers, broad perianth segments, yellow anthers, and wet-ground habitat are diagnostic. Genetic instability in this subspecies is frequently expressed as malformed flowers with shrunken or missing reproductive structures.
