[saveplants.org] Limited Range, Bloom, Description: This perennial hemiparasite (root parasite) is an endemic to the San Gabriel Mountains, with a limited range in the western part of the mountain range in the Mount Gleason area. Its scarlet inflorescence is showy like many other related paintbrushes, blooming from April to July, however this taxon is distinguished by the presence of branched hairs throughout (Mistretta and Brown 1987).
