Orobanchaceae (Broomrape Family)


Desert indian paintbrush (formerly named Castilleja angustifolia) is a gray-green few branched herbaceous perennial from a woody root-crown with alternate, lanceolate leaves that sometimes have 1-5 pairs of narrow, ± spreading lobes.  The calyx and leaflike bracts are scarlet-tipped.  The corolla's upper lip is about 1/2" long, sparsely pubescent, with wide reddish margins, the lower lip is dark green and only 1/16" long, and the stigma is 2-lobed.  This species of paintbrush is commonly found on dry and rocky slopes of the Mojave Desert in sagebrush and shadscale scrub, joshua tree and pinyon-juniper woodland to 8000', and blooms from April to August. These pictures were taken in Joshua Tree National Park.
