Ranunculus andersonii is a species of buttercup known by the common name Anderson's buttercup.[1] It is native to the western United States, including the Great Basin and surrounding regions, where it grows in sagebrush, woodlands, and other habitat. It is a perennial herb producing a basal rosette of thick leaves which are each divided into three double-lobed leaflets at the end of a petiole. The inflorescence arises from the rosette on an erect, leafless stalk usually no more than 20 centimeters tall. It bears one flower with usually five white or red-tinged petals each up to 2 centimeters long with white or pinkish sepals at the base. At the center of the flower are many yellow stamens and pistils. The fruit is an achene, borne in a spherical cluster of 14 or more. It was named after Charles Lewis Anderson by Asa Gray.[2]
