Dugaldia hoopesii

Synonyms: Dugaldia hoopesii, Helenium hoopesii. Hymenoxys hoopesii.  (Orange Sneezeweed)
Asteraceae (Sunflower Family)

Montane, subalpine, alpine. Meadows. Summer.
Lower Calico Trail, June 16, 2004.

From early to late summer, showy Dugaldia hoopesii plants are common, sometimes scattered in open woods, sometimes abundant in moist meadows from middle to high altitudes; they are always a pleasant sunny face to see along the trail. They are recognized by their mound of disk flowers; drooping, narrow, openly-spaced yellow/orange ray flowers; and deeply veined, almost white rib in the leaf.

The genus name honors Dugald Stewart, 18th century Scottish philosopher.  Thomas Hoopes, 1834-1925, was a prospector, explorer, and seed collector in Colorado for a few years in his twenties until he returned to his Chester, Pennsylvania home, farming, and a very successful wheelwright business.  (More biographical information about Dugald Stewart.)  (More biographical information about Thomas Hoopes.)

Asa Gray named the plant Helenium hoopesii in 1864, Per Axel Rydberg renamed it Dugaldia hoopesii in 1900, and the Synthesis of the North American Flora accepts the name Hymenoxys hoopesii given by Bierner in 1994.  The type specimen is variously attributed to Hoopes or to Hall and Harbour, both in 1862.
