World wide there are about 800 species. Some species are trees bearing eatable fruit. The low growing wood sorrels we know here are common within their range. Some of the low growing yellow flowered Wood Sorrels are common "weeds" of lawns and fields. The sour tasting leaves and pickle shaped seed pods may be eaten fresh but not in great amounts. The scientific name Oxalis comes from the Greek and means "sharp" and the common name "Sorrel" means "acidic" or "sour". Both refer to the taste of the plant.

Medical Uses: Several writers have indicated that the plant could quench thirst and it has been touted for its ability to heal sores especially of the mouth, but old sores and "cancers" on the skin as well. It was also used to cool fevers and treat urinary problems. Warning The plant contains oxalic acid which is toxic in very large doses.

By: Newcomb, Lawrence and Illustrated by Morrison, Gordon. 1977, Little, Brown and Company, ISBN:0-316-60442-9

One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.
