Oxalis albicans is a prostrate species, generally growing along the ground, and sometimes rooting at the leaf nodes. Plants typically produce two to eight stems, becoming woody at the base with age. Stems are covered with short, white, spreading hairs. Leaves are trifoliate, the leaflets lobed, or divided, up to a third of their height. Leaflets have a sparser covering of more straggly hairs, lying against the surface.
Flowers are formed of five non-fused sepals and five yellow petals, usually flecked with red lines at the base. There are ten stamens - in two groups, one higher than the other - and five styles.
