Taxonomic Comments
FNA (vol. 17, 2019) and Kartesz (1994) recognize Castilleja peirsonii as a distinct species from C. parviflora. "C. peirsonii has shorter, wider corolla beaks than the related C. parviflora. In addition to the corolla shape differences, C. peirsonii also has red to yellow bracts and fairly bright yellow corollas, especially on the beaks, while C. parviflora has purple, pink, or white bracts and greenish corolla tubes and dorsal beak surfaces, with the beak margins pink, purple, or white. Reports of C. peirsonii from outside the Sierra Nevada in California and immediately adjacent Nevada are misidentifications" (FNA vol. 17, 2019). Jepson Flora Project (2026) notes that C. parviflora has been misapplied to C. peirsonii. Differing from FNA (vol. 17, 2019) and Kartesz (1994), Kartesz (1999) included C. peirsonii in C. parviflora var. parviflora.
