The lower leaves of graceful ranunculus are similar to the basal leaves, the petioles are gradually shortened upward, and the leaves are smaller, 3-parted, lobes lanceolate, canine-toothed, or subdivided; the uppermost leaves are linear, entire, and sessile.
The flowers of graceful ranunculus are 1.5-2.2 cm in diameter; pedicels up to 8 cm long, adnate pilose; sepals elliptic, 4-6 mm long, white pilose; petals 5, obovate-round, 6-11 mm long, 4-8 mm wide, with claws about 0.5 mm long at the base, nectar scales 1-2 mm long; anthers about 1.5 mm long; receptacles short and glabrous.
The aggregated fruit of graceful ranunculus is nearly spherical, 6-8 mm in diameter; the achenes are flat, 2-2.5 mm long, the widest part of the upper part is nearly equal to the length, about 5 times thicker, and the edge has a rib with a width of about 0.2 mm.
