'''''Oxalis pes-caprae''''' ('''Bermuda buttercup''', '''African wood-sorrel''', '''Bermuda sorrel''', '''Buttercup oxalis''', '''Cape sorrel''', '''English weed''', '''Goat's-foot''', '''Sourgrass''', '''Soursob''', '''Soursop'''is a species of flowering plant in the wood sorrel family ''[[Oxalidaceae]]''. ''Oxalis cernua'' is a less common synonym for this species.
The flower is [[floral symmetry|actinomorphic]], with a [[calyx]] composed of five free or slightly fused [[sepal]]s, a [[sympetaly|sympetalous]] [[corolla (flower)|corolla]] composed of five fused petals, an apoandrous [[androecium]] composed of ten free [[stamen]]s in two ranks, and a compound [[gynoecium|pistil]].
Indigenous to South Africa, Bermuda buttercup is a highly [[invasive species|invasive]] [[weed]] in many parts of the world.<ref>http://www.dpi.vic.gov.au/DPI/VRO/vrosite.nsf/pages/weeds_herbs_perennial_soursob</ref> It is often called by the common name [[sourgrass]] or soursob due to its pleasant sour flavor. This sourness is caused by [[oxalic acid]], which is toxic in large quantities and may contribute to kidney stones.
