This common tiny Sunflower, found only above tree-line, forms small mounds from three to twelve inches in diameter topped with bright flowers.  Leaves are long, narrow, upright, prominently veined, and fringed with tiny hairs.  The plant is found in alpine meadows and tundra, often in the meager soils collected around rocks.  A quick glance could lead you to identifying this as Heterotheca pumila.  One of the great joys of botany is constantly being reminded to look and then look again.

"Tonestus" is a meaningless anagram of "Stenotus", another Sunflower genus.  John Torrey and Asa Gray named this Haplopappus pygmaeus and Aven Nelson, who named this genus in 1904, renamed it Tonestus pygmaeus.
