is one of several paintbrush species endemic to coastal regions of California. It is most common around San Francisco Bay and Point Reyes, extending south along the Big Sur coast and north into Humboldt County.
Stems branch readily and bear many, closely-spaced leaves, generally green, often tinged purple or yellow. All plant parts are covered both by long bristly hairs and shorter glandular hairs. Hairs are unbranched.
The elongated inflorescence extends along up to 7 inches of the stem. Bracts (usually three-lobed) are colored red, purple or yellow, and are between half and one inches long. The yellow or reddish-pink calyces are divided above and below to around half their length, and to a lesser degree at the sides. Calyces are around one inch long, and contain the tubular greenish-yellow corollas, projecting just a little way beyond.
