General Description
Perennial. Stems erect, simple or branched, 10–50 cm. Herbage puberulent. Leaves 2–6 cm long, linear, at least the uppermost with 1 or 2 pairs of linear lobes. Inflorescence villous; bracts usually yellow (red), lanceolate with usually 1 pair of narrow lobes. Flowers: calyx 14–23 mm long, primary clefts subequal to slightly deeper adjacent to the corolla lip than the back, lobes acute, 2–5 mm long; corolla green to yellow, 16–25 mm long, galea 5–9 mm long, lower lip much smaller than the galea (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).

Our plants are varieties flava and rustica (Piper) N.H.Holmgren.
