Ranunculus orthorhynchus var. bloomeri

Bloomer's beaked buttercup

Family: Ranunculaceae · Type: perennial · Native

Bloomer's beaked buttercup is a California native perennial found in northern coastal California regions including North Coast Ranges Outer, North Coast Ranges Inner, and San Francisco Bay Area in meadows and marshy areas at elevations below 100 meters. Flowering from March to May, this plant produces bright yellow flowers with petals 6 to 9 millimeters wide that are gently notched at the tip. Growing with low-spreading stems, it develops basal leaves that are heart-shaped to rounded, sometimes simple and sometimes divided into undivided leaflets with softly scalloped edges. Its distinctive leaves are rounded to occasionally slightly pointed, creating a delicate ground-hugging appearance. The fruit develops a short 1.8 to 2.2 millimeter beak, forming a small hemispheric to ovoid aggregate cluster.
