Description
The Wood Sorrel, (Oxalis carnosa), is generally included within (as a synonym of) Oxalis megalorrhiza, suggesting that there is not really a fundamental difference between the two. The name carnosa, meaning “fat, succulent”, refers to the swollen rootstock and short frutticose stems leafy and ?oriferous only at apex. The succulent roots helps distinguish this sorrel from the other herbaceous species.

Notes
The name Oxalis magellanica is unresolved but some evidences suggests it may be synonym of Oxalis carnosa.
