Description
"Caulescent or acaulescent, herbaceous perennials with rhizomes or bulbs, or annuls with fibrous roots. Leaves alternate, ternately compound, leaflets 3, obcordate; stipules very small or obsolete. Flowers in pedunculate umbels or cymes, or solitary. Sepals 5; petals 5 separate or adnate to each other just above the base; stamens 1-, of 2 lengths. Pistil with 5 carpels. Capsule longitudinally dehiscent. Seeds red, prominently reticulate, pitted or smooth, each completely enclosed by an elastically dehiscent, transparent aril that aids in its distribution. Heterostyly is typical of plants in this genus. " [2]
"Caulescent, stoloniferous herb with fibrous roots. Stolons completely prostrate, usually bearing roots at each node, and usually flowering from the axils of leaves from rooted nodes. Stems, petioles, and peduncles, slightly pilose. Leaflets green, reddish or purplish, ca. 2 cm long or often considerable less. Peduncles mostly shorter than the subtending petioles, mostly 1-or 2-flowered. Sepals not gland-tipped; petals yellow, 5-7 mm long. Capsule prismatic, 0.8-1 cm long, sparsely pubescent. Seeds reticulate." [2]
Distribution
O. corniculata is native of New World tropics and subtropics, but is now nearly worldwide in distribution.[1]
Ecology
Habitat
O. corniculata occurs in moist to dry sandy or loamy soils. [3] It can be found in lowland woodlands, as well as disturbed sites, including along trails, mowed lawns, and near man-made ponds. [3]
Phenology
O. corniculata flowers from February through December.[1]
Seed bank and germination
Commonly found in seed banks of disturbed areas. [4] Forms a persistent soil seed bank. [5] Found in the seed bank of an ectone region of longleaf pine and scrub communities in the western panhandle of Florida. [6]
An early 2000s study found that O. corniculata is found in the seed banks of pine flatwoods and old agricultural field soils.[7]
Fire ecology
Populations of Oxalis corniculata have been known to persist through repeated annual burning.[8]
Conservation, cultivation, and restoration
Cultural use
Wood sorrel is edible in small quantities on salads. The plant can act a sort of tonic and is supposedly refreshing to eat.[9]
