Derivation of the botanical name:
Oxalis, Greek oxys, acid, sour, sharp; referring to the taste of the leaves and the stem; Pliny used Latin oxalis, idis, for some species of Rumex.
Acetosella, Latin acetosus, acid, sour, refers to the leaves sour taste; a pre Linnaean name for common sorrel and other plants with acid leaves.
- The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.
