Eucephalus engelmannii

Engelmann's Aster

Eucephalus engelmannii (D. C. Eaton) Greene is native to open coniferous forests and montane and subalpine meadows from British Columbia and Alberta south to Nevada, Utah and Colorado (Allen 2006 FNA).  The species is distinguished by its 50–150 cm tall stems, 5–10 cm, elliptic to lanceolate leaves, either glabrous and eglandular, or abaxially somewhat glandular and/or villous), and white to pink rays.  The species is diploid (2n=18).

Morphs of E. engelmannii from the Cascade Mountains with more densely pubescent leaves  on the under faces may indicate intergradation with E. ledophyllus (Allen 2006 FNA).
