Purple coloration of sepals

Very early flowering perennial with bright yellow flowers, flowers measured to 20 mm diameter. Flower petals are ovate, sepals have a purplish coloration. Stems are glabrous, leaves glabrous to sparsely hairy. As outlined in Budd's Flora and shown above, plants have two very different basal leaves - lanceolate and entire, we measured on of these basal leaves at 45 mm long (including petiole) and 10 mm wide; or, wedge-shaped and broader, and having three lobes, we measured one of these leaves at 3 cm long and 15 mm wide. Stem leaves are alternate, and deeply divided into 3 lanceolate leaflets

Habitat is prairie grassland. Fairly common.

We measured plants to 6 cm tall.

The above photos were taken on May 2nd, grassy meadow, Oro Lake about 150 km southwest of our home in Regina, SK.
