Oxalis dillenii
Also called Sussex Yellow Sorrel, Slender Yellow Wood Sorrel, Southern Yellow Wood Sorrel, Dillen's Oxalis, Dillen's Wood Sorrel, Dillenius' Wood Sorrel, Erect Wood Sorrel
Slender yellow woodsorrel is a small, clover-leaved perennial weed of the Oxalis genus, often found in lawns, gardens and disturbed ground. It is grown as a garden plant mainly for its clover-like leaves and small yellow flowers, and it spreads readily by seed.
Oxalis dillenii, the southern wood-sorrel, slender yellow woodsorrel, or Dillen's oxalis, 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 stricta and Oxalis florida. 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.
Oxalis dillenii is insect pollinated and is recorded to have been visited in northern Florida by Augochloropsis metallica, Bombus impatiens, Ceratina, Lasioglossum creberrimum, Lasioglossum pectorale, Lasioglossum tegulare/puteulanum, Lasioglossum vierecki,and Lasioglossum weemsi/leviense.
