Bush morning-glory - Ipomoea leptophylla
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.

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 (
