Discussion

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).

Varieties 2 (2 in the flora).

The leaves of Pedicularis centranthera exceed the inflorescence, giving the impression that the cauline leaves are basal. Proximalmost basal leaves are distinct: brown, membranous, and spatulate with undivided and entire margins. Pedicularis semibarbata has similar basal leaves.

Pedicularis centranthera occurs in evergreen forests, often under pinyon pine, juniper, ponderosa pine, and yellow pine.
