Species: Ranunculus cardiophyllus
Encyclopedia of Puget Sound
Heart-leaved Buttercup is a fibrous-rooted perennial with erect, branched stems that are 15-40 cm high. The basal leaves have spade-shaped blades that are 2-6 cm long and toothed margins and petioles that are 2-12 cm long. The few, alternate stem leaves are deeply divided like fingers on a hand. The foliage is covered with straight, spreading hairs. Stalked flowers arise from the axils of the uppermost leaves, or bracts, forming an open, few-flowered inflorescence. Each saucer-shaped flower has 5 yellowish sepals that fall off shortly after opening, 5 yellow petals that are 8-15 mm long, each with a small basal pocket with long hairs at the top, and numerous stamens and ovaries. The cylindric fruiting heads bear 20-100 flattened, egg-shaped, hairy achenes that are 1-2 mm long; each has a short, straight beak on top.
