Small creeping buttercup is a low growing perennial with lax to prostrate stems up to 50 cm long. The stems commonly root at the nodes as they touch the ground and they may be somewhat hollow. The stems are either simple or may have some simple branching. The herbage varies from smooth to covered with stiff hairs. The leaves alternate along the stem and are simple with entire margins. The blades range from oblanceolate to narrowly linear. The basal leaves have long petioles while the stem leaves are short petiolate or sessile.

The 5 sepals are 2-5 mm long while the 5 (to 11) yellowish petals are 4-5 mm long.
