Discussion

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.
