Description

Differentiating between Slender Yellow Woodsorrel and Common Yellow Woodsorrel (Oxalis stricta) can be tricky. Looking at the seeds of the plant is the best way to identify these two species. Common Yellow Woodsorrel has seeds that are plain brown. In contrast, the seeds of Slender Yellow Woodsorrel are brown, with prominent white ridges. Checking the hairs on the stem is another way to separate the two species. The stem hairs of Common Yellow Woodsorrel are dense and spreading, while the stem hairs of Slender Yellow Woodsorrel are appressed.

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. Oxalis dillenii can be confused with other small yellow flowered species in North America, such as Oxalis florida.[4] 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.[5]
