Pedicularis langsdorffii
Pedicularis dudleyi
Subspecies 2 (2 in the flora).
Pedicularis langsdorffii may be mistaken for P. hirsuta, P. lanata, and P. sudetica, which have similar growth forms and habitat requirements. Pedicularis langsdorffii generally has larger, pink to lavender corollas with toothed galeas that strongly arch over the abaxial lips in contrast to the smaller, toothless, pink corollas and slightly arching galeas of P. lanata. Pedicularis sudetica has up to five cauline leaves or lacks them. The straight, smaller galeas and pale pink or white corollas of P. hirsuta differentiate it from P. langsdorffii.

Shapes of flowers and leaves of Pedicularis dudleyi are similar to those of P. semibarbata; P. dudleyi has larger vegetative features. Floral features that set P. dudleyi apart include a 10–14 mm calyx and pink to purple corolla versus a 7–9 mm calyx and pale yellow corolla in P. semibarbata.
Pedicularis dudleyi occurs in the coastal mountains of central California in Monterey, San Luis Obispo, San Mateo, and Santa Cruz counties.
