Oxalis stricta - L.                
                 
Common Name Yellow Wood Sorrel
Family Oxalidaceae
Synonyms O. dillenii.
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].
Range Eastern N. America - Nova Scotia to Florida and Texas. E. Asia. A rare introduction in Britain.

This variety differs from O. corniculata by stems erect, not rooting at nodes; branched or not[266].
                                                                                 
Propagation

An excellent and very comprehensive guide but it only gives very short descriptions of the uses without any details of how to utilize the plants. Not for the casual reader.

The most comprehensive guide to edible plants I've come across. Only the briefest entry for each species, though, and some of the entries are more than a little dubious. Not for the casual reader.

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