		bush penstemon, shrubby penstemon
Habit		Bushy-branched, ascending or erect shrubs, the stems 1.5-4 dm. tall, glabrous except for the stalked glands in the inflorescence.
Leaves		Leaves opposite, the larger leaves crowded toward the base of the season\\\\'s growth on short, sterile shoots, the blades entire or toothed, up to 6 cm. long and 1.5 cm. wide, short-petiolate; flowering shoots with reduced and less-crowded leaves.
Flowers		Inflorescence a short, few-flowered, bracteate raceme, with simple, axillary pedicels; calyx 7-15 mm. long, with 5 lanceolate, long-acuminate segments; corolla blue-lavender to light purplish, 30-50 mm. long, 1 cm. wide at the mouth, keeled on the back, glabrous outside, with long, white hairs on the base of the lower lip within; anthers long-woolly, the pollen sacs wholly dehiscent and opening wide enough to form a plane; staminode slender, shorter than the 4 fertile filaments, long-bearded toward the tip.
Fruits		Capsules 8-12 mm. long.
