Plant: Perennial up to 25 inches tall, ascending to erect stems, moderately hairy and may be somewhat glandular-hairy. This variety is distinguished by its linear to broadly oblong, often perpendicular, distal stem leaves and often congested, corymb-arrays.
Leaves: Stem leaves linear to broadly oblong 3/8 to 1-inch long; becoming smaller upward; rounded bases and flat edges; surfaces moderately hairy and/or glandular-hairy.
Inflorescence: Usually congested corymb-like arrays with 2 to 20 composite flower heads 3/4 to 1-1/2 inches across, each with 11 to 19 yellow rays; 1 to 4 bracts just below the head are linear-oblong; involucres are cylindrical to bell-shaped; phyllaries are narrowly triangular-lanceolate and have edges and tips that are sometimes reddish or purplish and moderately hairy surfaces that are sparsely to densely glandular.
Bloom Period: May to October.
