	Penstemon ovatus	Penstemon gairdneri
	egg-leaf beardtongue, broad-leaved penstemon	gairdner's penstemon
Habit	Robust perennial from a woody base, the clustered stems 3-10 dm. tall, with stiff, spreading hairs below the inflorescence	Plants from a branched, woody base, the several, erect stems 1-4 dm. tall, also with short, densely-leafy sterile stems which tend to form loose mats; herbage finely gray-puberulent, with a few stalked glands in the inflorescence.
Leaves	Basal leaves opposite, clustered, petiolate, with ovate to sub-cordate blade up to 10 cm. long and half as wide, about equaling the petiole, serrate, hairy like the stem, especially along the mid-vein beneath; cauline leaves sessile and clasping, more sharply serrate, nearly as large, but more broadly oblong, the upper ovate.

Inflorescence of several few-flowered verticillasters; calyx 3.5-8 mm. long, the 5 segments broadly lanceolate, entire; corolla blue-purple or lavender, or occasionally bright rose-purple, 14-22 mm. long, somewhat glandular-hairy externally and internally near the mouth, the tube flared, the limb spreading; pollen sacs glabrous, ovate, 0.8-1.2 mm. long, becoming opposite; staminode bearded toward the tip.

Penstemon gairdneri

egg-leaf beardtongue, broad-leaved penstemon

gairdner's penstemon

Habit

Robust perennial from a woody base, the clustered stems 3-10 dm. tall, with stiff, spreading hairs below the inflorescence

Plants from a branched, woody base, the several, erect stems 1-4 dm. tall, also with short, densely-leafy sterile stems which tend to form loose mats; herbage finely gray-puberulent, with a few stalked glands in the inflorescence.

Leaves

Basal leaves opposite, clustered, petiolate, with ovate to sub-cordate blade up to 10 cm. long and half as wide, about equaling the petiole, serrate, hairy like the stem, especially along the mid-vein beneath;

cauline leaves sessile and clasping, more sharply serrate, nearly as large, but more broadly oblong, the upper ovate.

Leaves numerous, opposite to alternate, or irregularly scattered, entire, linear, seldom over 3 mm. wide.

Flowers

Inflorescence large and open, strongly glandular-hairy;

calyx 3-5 mm. long, broadly lanceolate, with parallel veins;

corolla blue, 15-22 mm. long, glandular-hairy on the outside, the raised portion of the lower petal pale blue and hairy;

corolla strongly bilabiate, the lower lip much the longer;

pollen sacs 0.8-1.1 mm. long, fully dehiscent and becoming opposite, nearly glabrous;

staminode bearded toward the recurved tip.

Inflorescence of several few-flowered verticillasters;

calyx 3.5-8 mm. long, the 5 segments broadly lanceolate, entire;

corolla blue-purple or lavender, or occasionally bright rose-purple, 14-22 mm. long, somewhat glandular-hairy externally and internally near the mouth, the tube flared, the limb spreading;

pollen sacs glabrous, ovate, 0.8-1.2 mm. long, becoming opposite;

staminode bearded toward the tip.

Fruits

Capsule 4-6 mm. long.
