Pedicularis parryi
Pedicularis labradorica
Subspecies 3 (3 in the flora).
Pedicularis parryi is characterized by a domed galea with a conical beak and light green calyces and floral bracts with dark purple stripes. The beaked galea extends well beyond the expanded lobes of the abaxial lip.
Pedicularis parryi is an alpine complex. Corolla color, number of cauline leaves, and bract margin variation are important features differentiating infraspecific taxa within P. parryi (G. D. Carr 1971, from which the following key is adapted).

The flowers of Pedicularis labradorica are usually yellow or dark yellow, and the galea is tinged distally with red or purple; sometimes, the yellow color of the tube abruptly transitions into red or purple. Hultén based var. sulphurea on the solid yellow color variant from the Yukon.
