State Rank Reason (see State Rank above)
Known in Montana from only a few collections in the southeastern part of the state, only 1 of these collections was in the last 2 decades. This is a very conspicuous, attractive species, so it is probably not undercollected.
General Description
Glabrous perennial with an enlarged root. Stems ascending to erect, 30–100 cm. Leaves short-petiolate; blades linear-lanceolate, entire, 3–12 cm long. Inflorescence few-flowered, axillary cymes; peduncles ca. 1 cm long. Flowers: calyx 5–10 mm long, lobes ovate, the inner longer and wider; corolla lavender, 5–7 cm long; stamens unequal, included. Capsule 10–15 mm long, beaked (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).

Diagnostic Characteristics
This distinctive plant is not easily mistaken for anything else in Montana. It has reddish, funnel-shaped flowers that are several inches long. The stems are woody at the base and creep along the ground. It has the general appearance of a morning glory.
