The trifoliate leaves are subdivided into three rounded leaflets and resemble a clover in shape. Some varieties have green leaves, while others, like Oxalis corniculata var. atropurpurea, have purple. The leaves have inconspicuous stipules at the base of each petioles.

The fruit is a narrow, cylindrical capsule, 1 to 2 cm long and noteworthy for its explosive discharge of the contained, 1 mm long seeds.


This species is cosmopolitan in its distribution, and its place of origin is unknown. It is regarded as weed in gardens,agricultural fields, and lawns.
