GBIF's records not checked. GBIF's backbone holds no one accepted species of this name, and a name it holds only as another species' synonym is not taken for this one, so GBIF's records were not asked. So this page has no points on its map, no map marker, no habitat climate, no cultivation sheet and no species of nearest climate; the range is Kew's. Not a statement that none exist. How.

They are a common flower found in moist habitats near or above timberline in the Rocky Mountains and the Pacific Northwest. Like most members of the Castilleja genus, they are partially parasitic plants.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence.
