Other info. - This species is very common in Missouri and is found throughout the state. The pubescence of the stems and leaves is very variable and Steyermark breaks the plant into many varieties and forms. These taxa are probably not valid and won't be mentioned here. This species can be eaten and adds a nice sour flavor to salads. Large quantities of the plant should be avoided because of its oxalic acid content.
The yellow flowered species of Oxalis can be difficult to differentiate. Mature, flowering specimens are required for a proper ID.
