Oxalis corniculata
O. corniculata is a small variable, prostrate, creeping herb, somewhat pubescent with long, scattered hair, the stems creeping, up to 50 centimeters in length, usually rooting at the nodes. Leaves are trifoliate, with three small heart-shaped leaflets, their petioles 5 centimeters long or less, sessile. Leaflets are obcordate, 0.5 to 1.5 centimeters long and stalkless. At noontime, the leaflets droop like folded umbrellas. At night, the leaflets close and fold together. Flowers are yellow, one to several on each peduncle, subumbellately disposed, nearly 1 centimeter long. Petals are obcordate. Fruits are capsules, hairy, tomentose, subcylindric, 1 to 1.8 centimeters long, divided into minute segments with numerous black seeds the size of sand grains. [stuarxchange.com]
