Pedicularis dudleyi is a rare species of flowering plant in the family Orobanchaceae known by the common name Dudley's lousewort.
It is endemic to central California, where it is known from about ten scattered occurrences along the coast and in the coastal mountain ranges.
The species is a hairy perennial herb and produces one or more stems 10 to 30 centimetres (3.9 to 11.8 in) tall from a caudex.
[1] Fewer than 10 known locations are known to support the plant in three areas along the Central California coast, including specific sections of Pescadero Creek in the Santa Cruz Mountains, the Arroyo De La Cruz In the South Santa Lucia Mountains, and one site within the boundary of Boy Scout Camp Pico Blanco.
[2] Monterey County cited the Scouts in 1989 for their "repeated destruction of Dudley's lousewort and its habitat.
