Discussion

Iliamna longisepala is distinctive in its long calyx and calyx lobes. The species is rare and limited to the eastern side of the Wenatchee Mountains in the arid transition zones over a total distance of about 120 kilometers in Chelan, Douglas, and Kittitas counties.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Iliamna comprises one widespread species of the mountainous West (I. rivularis), and seven local species (two eastern and five western) differing principally but modestly in pubescence, leaf, involucellar bractlet, and calyx characters, and exhibiting varying degrees of intergradation. All, with the exception of I. bakeri, are species of relatively mesic, open woodlands, scrub, and meadows, often along stream banks. Each of the species apparently regenerates following disturbance or fire, sometimes in dense stands.

Species 8 (8 in the flora).
