PLANT: Short-lived perennial, 35-100 cm tall, simple to branched at base; stems often woody at base, with short glandular hairs, nonglandular below.

LEAVES: subglabrous to sparsely short-pilose, deeply lobed.

INFLORESCENCE: narrow, one-sided, with subsessile to short-pedicelled flowers on lateral branches.

FLOWER: calyx 4-6 mm long, short glandular pubescent, the lobes acute to acuminate; corolla white to lavender, the tube 25-35 mm long, the throat 2-4 mm wide, the lobes lanceolate to ovate, acuminate to apiculate, often with pink to lavender flecks; stamens inserted unequally on the tube; filaments unequal; anthers included to slightly exserted; stigma slightly exserted.

CAPSULE: 5-8 mm long; seeds 6-12 per locule. 2n=14.

General: Short-lived perennial, 35-100 cm tall; stems erect, simple or branched at the base, glandular-puberulent above, puberulent without glands below, base often woody.

Leaves: Basal (forming a rosette, this often withered by flowering) and cauline, alternate, deeply pinnately lobed into linear segments, 2-5 cm long, nearly glabrous to sparsely pilose.

Flowers: Inflorescence of terminal and axillary clusters, somewhat diffuse to one-sided, the flowers nearly sessile, crowded; calyx 4-8 mm long, glandular-puberulent, the tips short-aristate; corolla pale violet to purplish, the tube 5-15 mm long, the lower 3 lobes partially united, often with purple flecks; anthers exserted; stigma slightly surpassing the anthers; flowers June-September.

Fruits: Capsule, ovoid, 5-8 mm long.

Ecology: Meadows, coniferous forests, open habitats; 2100-2700 m (7000-9000 ft); Apache, Coconino, Graham, Pima, and Yavapai counties; western and southwestern U.S.

Notes: Ours, as here described, belong to ssp. latiloba. Ipompsis tenuituba apparently hybridizes with I. aggregata on the San Francisco Peaks, on the Kaibab Plateau, and in the White Mountains, producing intermediates in corolla size and color. Ipomopsis macrosiphon (longtube ipomopis) [=Gilia aggregata var. macrosiphon] is very similar to I. tenuituba, but is distinguished by a larger corolla tube (30-40 mm long), the lobes lavender to purple with dark purple flecks. It occurs in coniferous forests, usually in sandy to gravelly soils.
