This has bright yellow flowers like the other wood-sorrels, but they are a little larger (1.5 cm across). They usually have 2 red dots, or a red smear, at the base of each petal. There are 2–7 flowers, on short (< 2 cm) pedicels. Leaves may be green, or olive, or even purplish. The leaves are glabrous above, but with hairs on the margins. Leaflets are sometimes open, sometimes half-closed.
