A very variable species in form and size. Common during the spring season from the plains to 2700 m. The leaves can be used as vegetable. The juice of the plant mixed with onion is used to remove warts.

This species is used medicinally.

This highly successful weedy species is so widespread, particularly in areas disturbed by humans, that its origin is unknown. It has been reported from China in additional provinces, such as Heilongjiang, Jilin, Ningxia, and Xinjiang, where it is likely a weed in protected locations, such as in greenhouses. The most frequently encountered variety in China is Oxalis corniculata var. villosa (M. Bieberstein) Hohenacker, but this variety is often under-recorded due to the glabrescent nature of the adaxial surface of the leaves. Oxalis corniculata var. villosa has leaflet blades covered with trichomes all over the abaxial surface, whereas for var. corniculata the abaxial surface has trichomes only on the midrib of the terminal leaflet and the basal half of the lateral leaflets. Plants with leaves, and to a lesser extent all vegetative parts, suffused purplish red are Oxalis corniculata var. atropurpurea Planchon. The purple coloration is conspicuous in plants from exposed sunny habitats but is much less prominent in shaded plants and fades on drying, making confident determination of old herbarium specimens difficult. Determination of the exact distribution of these varieties in China needs additional study.

Synonyms of Oxalis corniculata var. villosa include: Oxalis villosa M. Bieberstein, Fl. Taur.-Caucas. 1: 355. 1808; Acetosella corniculata var. villosa (M. Bieberstein) Kuntze; ?O. corniculata f. maritima Masamune; O. corniculata var. sericea Knuth; O. corniculata var. trichocaulon H. Léveillé; O. corniculata f. villosa (M. Bieberstein) Goiran; ?O. corniculata var. viscidula Wiegand; O. langloisii (Small) Fedde; O. thunbergiana Montrousier; Xanthoxalis langloisii Small. Synonyms of Oxalis corniculata var. atropurpurea include: Oxalis corniculata f. purpurea (Parlatore) Knuth; O. corniculata var. purpurea Parlatore; O. tropaeoloides Schlachter ex Planchon; Xanthoxalis corniculata f. atropurpurea (Planchon) Nakai; X. corniculata var. atropurpurea (Planchon) Moldenke; X. corniculata f. purpurea (Parlatore) Nakai.

Oxalis albicans

provided by wikipedia EN

Oxalis albicans, commonly known as radishroot woodsorrel, is North American species of perennial herbs in the woodsorrel family. It is widespread in Mexico (from Baja California east to Coahuila and south as far as Oaxaca) and the southwestern United States (California, New Mexico, Arizona, western Texas).[2]

In California, the species grows in chaparral, coastal sage scrub, and other habitats, from sea level to elevations of 2,296 feet (700 m). The plant is found in the California Coast Ranges, Sierra Nevada, Transverse Ranges, Peninsular Ranges, and other regions of the state.[3]

Former subspecies

Currently recognized Oxalis species, that were formerly considered Oxalis albicans subspecies, include:[4]

Oxalis corniculata

provided by wikipedia EN

 src=
Purple leaved variety.

Oxalis corniculata, the creeping woodsorrel, also called procumbent yellow sorrel[1] or sleeping beauty, resembles the common yellow woodsorrel, Oxalis stricta. It is a somewhat delicate-appearing, low-growing, herbaceous plant in the family Oxalidaceae.

Description

It has a narrow, creeping stem that readily roots at the nodes. The trifoliate leaves are subdivided into three rounded leaflets and resemble a clover in shape. Some varieties have green leaves, while others, like Oxalis corniculata var. atropurpurea, have purple. The leaves have inconspicuous stipules at the base of each petiole.

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.

Pollen of Oxalis corniculata

Distribution

This species probably comes from south-eastern Asia[2]. It was first described by Linnaeus in 1753[3] using specimens from Italy, and it seems to have been introduced to Italy from the east before 1500[2]. It is now cosmopolitan in its distribution and is regarded as a weed in gardens,[4] agricultural fields, and lawns.[5]

Uses

The leaves of woodsorrel are quite edible, with a tangy taste of lemons. A drink can be made by infusing the leaves in hot water for about 10 minutes, sweetening and then chilling.[6] The entire plant is rich in vitamin C. Any woodsorrel is safe in low dosages, but if eaten in large quantities over a length of time can inhibit calcium absorption by the body.[6]
