Common Name Yellow Wood Sorrel, Common yellow oxalis, Common Yellow Wood Sorrel, Oxalis

Known Hazards The leaves contain oxalic acid, which gives them their sharp flavour. Perfectly all right in small quantities, the leaves should not be eaten in large amounts since oxalic acid can bind up the body's supply of calcium leading to nutritional deficiency. The quantity of oxalic acid will be reduced if the leaves are cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[238].
Habitats Dry open soils[43]. Prefers impoverished soils, growing in abandoned fields, roadsides etc[159].

We always called it sourgrass, as we found it sour when we chewed it. The flowers and seedpods are especially sour.
