Most buttercups are yellow or white, but ranunculus andersonii
is an exception; the five rounded petals and the five pointed, spreading sepals are pink; very pale at first, becoming steadily darker as they mature. Petals are crossed by darker, lengthwise veins. The center of the flower contains a ring of yellow/orange stamens around a group of greenish pistils. Flowers grow singly at the top of leafless stems, which may be erect or leaning; plants typically produce half a dozen blooms. The basal leaves are heart-shaped in outline, but divided into three leaflets, each split into rounded lobes.
