en List of Castilleja species

This is a list of the species in the genus Castilleja. They are commonly called paintbrushes,^[1] painted-cups, or owl’s-clovers in English.^[2] These 218 species and two natural hybrids are considered valid by Plants of the World Online (POWO) as of 2024.^[3] This list largely agrees with World Flora Online (WFO) with some exceptions. WFO lists Castilleja eggeri as unchecked.^[4] It also spells some species names differently, Castilleja rhexiifolia with a single "i" instead of a double "ii", Castilleja tolucensis as Castilleja toluccensis, and Castilleja virgatoides as Castilleja virgayoides.^[5]^[3] In addition one of the two hybrids, Castilleja × cognata, is listed in WFO as a species rather than as a hybrid.^[6]
