Oxalis corniculata, the creeping woodsorrel, procumbent yellow sorrel^[2] or sleeping beauty, is a somewhat delicate-appearing, low-growing herbaceous plant in the family Oxalidaceae.

Oxalis corniculata is a small creeping type of woodsorrel that tends to grow well in moist climates.^[3] It resembles the common yellow woodsorrel, Oxalis stricta.

Description

It has a narrow, creeping stem that easily takes root at the nodes. Its trifoliate leaves are subdivided into three rounded leaflets, resembling a clover. Some varieties have green leaves, while others, such as Oxalis corniculata var. atropurpurea, have purple leaves. There are inconspicuous stipules at the base of each petiole. The small, yellow flowers have either round-edged or sharp-ended petals. The flowers close when the plant is not within direct sunlight, hence the name “sleeping beauty”. Some specimens can have a single flower while others can have over 20.

The fruit is a narrow, cylindrical capsule, 1–2 cm (0.4–0.8 in) long, and noteworthy for its explosive discharge of the contained seeds, 1 mm (0.04 in) long. Pollen is about 34 microns in diameter.
