About plant names...

Common paintbrush’ genus, Castilleja, is named for 18th century Spanish botanist Domingo Castillejo. Chromosa, meaning “color,” is a reference to the bright red flowerheads. If you’re interested in Castillejas, don’t miss Mark Egger’s superb photographic compilation on Flickr. See also this Castilleja comparison table.

Identification: Plants are less than 24" (60 cm) tall, sometimes as little as 4" (10 cm). Leaves are linear-lanceolate (long and narrow or shaped like a lance), composed of three to five narrow lobes, like fingers. They are ¾-2½" (2-7 cm) in length The intensely bright red (or red-orange or yellow) “flowers” are really bracts—modified leaves, each up to 1½" (3.8 cm) long. The real flowers are mostly hidden, tubular in shape, and yellow-green in color. They appear from May to September. Fruits are a two-chambered capsule. Unlike Castilleja angustifolia, this plant is found below 3200' (975 m); in fact, it is found below sea level, in Death Valley National Monument.
