Pedicularis procera
Pedicularis dudleyi
Although Pedicularis grayi A. Nelson appears in older floras, the name is superfluous and illegitimate. Pedicularis procera Adams ex Steven 1822 is invalid.
Pedicularis procera is the tallest species of Pedicularis in North America. Because the leaves closely resemble those of P. bracteosa, smaller plants can be easily mistaken for this species.

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.
