Species: Taraxacum eriophorum
Encyclopedia of Puget Sound
Rocky Mountain Dandelion is a stemless, herbaceous perennial with erect to ascending, glabrous or sparsely hairy flower stalks that are up to 3 dm tall when mature. The basally-disposed, tongue-shaped leaves are 6-20 cm long, are glabrous, and have wavy margins and broadly winged petioles. The sap is milky. Solitary, terminal flower heads are borne on 1 to many leafless stalks. Each head has 2 series of erect, lance-shaped involucral bracts. The inner bracts, at 15-25 mm high, are much longer than the outer bracts. The ray flowers are yellow, and disk flowers are absent. The reddish, 4-angled, narrowly elliptic achenes are 3-4 mm long and surmounted by a pappus. Each has a slender beak that is 2-4 times as long as the achene itself.
