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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Pedicularis pulchella occurs in the Absaroka and Beartooth ranges of southwestern Montana and northwestern Wyoming, the Anaconda and Madison ranges of Montana, and one site in the Cascade Range of Washington. The overlapping adjacent lobes of its two-, or sometimes three-, pinnatifid leaves are a characteristic feature of P. pulchella.
