Heads with ray and disk flowers, numerous in a spikelike, elongate inflorescence; involucres 4-6 mm tall; involucral bracts oblanceolate, evidently graduated, commonly blunt, glabrous; ray flowers yellow, 5-10, mostly 8, scarcely exceeding the 10-16 yellow disk flowers.
Fruits:
Achenes densely hairy; pappus of numerous white hairlike bristles.
Notes:
Three often difficult to separate varieties occur in BC.
1. Plants 10-60 cm tall, very strongly resinous and aromatic, with a spikelike, usually elongate inflorescence, and mostly spoon-shaped or egg-shaped basal leaves........................ var. spathulata
1. Plants 5-80 cm tall, less strongly resinous and aromatic; leaves and inflorescence various.
2. Plants of the subalpine and alpine zones, 5-15 cm tall, with a short, compact inflorescence; basal leaves spoon-shaped or egg-shaped........................ var. nana (A. Gray) Cronq.
2. Plants of the lowland and montane zones, 15-80 cm tall, with a more spikelike, elongate inflorescence; basal leaves mostly oblanceolate........................ var. neomexicana (A. Gray) Cronq.
