Distribution edit
Ranunculus glaberrimus is found from central British Columbia east to southern Saskatchewan, south through the Dakotas to Kansas, through the Rocky Mountains southeast to northern New Mexico, west to the Great Basin region, and southwest to northeastern California.
It occurs in habitat types with junipers (Juniperus occidentalis), sagebrush (Artemisia tridentata) and bitterbrush (Purshia tridentata), in damp ground.[2][3][4]
Description edit
Ranunculus glaberrimus is a herbaceous perennial plant growing to 4–15 centimetres (1+1⁄2–6 in) tall. The roots are clustered and fleshy.[4] The somewhat thick basal leaves are oval, with long petioles, ranging from entire to having three deep lobes. Cauline leaves have short petioles but are otherwise similar. The flowers have four to ten yellow petals (usually five)[4] about 1 cm long.[5] The sepals are yellow-purple,[4] and the stamens and pistils are numerous.[5] It flowers relatively early, typically in March and April, though occasionally blooming in February.[4][6]
The species is reportedly toxic to livestock and possibly to humans as well.[7]
