Oxalis pes-caprae is a species of tristylous yellow-flowering plant in the wood sorrel family Oxalidaceae. Oxalis cernua is a less common synonym for this species.

It is commonly known as African wood-sorrel, Bermuda buttercup, Bermuda sorrel, buttercup oxalis, Cape sorrel, English weed, goat's-foot, sourgrass, soursob or soursop; Afrikaans: suring; Arabic: hommayda (حميضة).

Some of the most common names for the plant reference its sour taste owing to oxalic acid present in its tissues. Indigenous to South Africa, the plant has become a pest plant in different parts of the world that is difficult to eradicate because of how it propagates through underground bulbs.

Oxalis pes-caprae is often called by the common name sourgrass due to its moderately sour flavor. This sourness is caused by an exceptionally high content of oxalic acid.

The specific epithet pes-caprae means 'goat's-foot', possibly in reference to the shape of the leaf.

The Oxalis pes-caprae flower is actinomorphic, with a calyx composed of five free or slightly fused sepals, a sympetalous corolla composed of five fused petals, an androecium composed of ten free stamens in two ranks, and a compound pistil. Native populations in South Africa are heterostylous, flowers of long-styled plants have a stigma held above the two ranks of stamens, mid-styled plants have the stigma in between the two ranks of stamens and short-styled plants have a stigma below both ranks of stamen. In the non-native range the plants largely reproduce vegetatively and many populations have only one style length and the plants never produce seed.

Like most African Oxalis species, it produces adventitious subterranean propagules. These take the form of true bulbs in botanical terms, which is unusual among dicotyledons. O. pes-caprae produces small bulbs copiously, whereas most other African species produce fewer, larger bulbs.
