Oxalis dillenii, the southern wood-sorrel,[2] slender yellow woodsorrel, or Dillen's oxalis,[3] is a species in the woodsorrel family. Like other Oxalis species, the leaves of this plant resemble clover leaves, with three leaflets. The flowers have five yellow petals that are 4 to 10 mm (0.16 to 0.39 in) in length. The leaflets are 1 to 2 cm (0.39 to 0.79 in) wide with pointed hairs. The fruits are rather brown and are 1.5 to 2.5 cm (0.59 to 0.98 in). It is often considered a weed, and can be found worldwide, but likely originated in North America.[4]
