General: Perennial herb or shrub, to 60 cm tall, arising from a large, woody caudex, probably root-parasitic, herbage retrorsely-hispidulous.

Leaves: Opposite, alternate or in whorls of three, narrowly linear, entire, often revolute.

Flowers: Brownish yellow or orange yellow, with a large corolla and short corolla tube, the throat swollen on one side, the calyx 3-4 mm long, the corolla 15-25 mm long, puberulent on outside, the flowers borne in loose, leafy racemes on long pedicels.

Fruits: Capsule 6-10 mm long, the beak at maturity splitting at the apex into 2 reflexed segments.

Ecology: Found on dry slopes and mesas, among live oaks, from 5,000-7,500 ft (1524-2286 m); flowering August-September.

Notes: The sight of the narrow leaves that are not opposite can be misleading, but the beautiful yellow foxglove flowers are distinctive. Also pay attention to the narrow leaves and how they are revolute.
