The Oxalidaceae (570 species), commonly known as the wood sorrel family, is a
small group of flowering plants with typically trifoliate leaves in clover-like
arrangement and thickened leaf bases of leaflets. Many members show “sleep
movements” i.e., the leaflets get folded together during the night or in response to
stress or touch. Some members are rich in Vitamin C, and potassium. The
presence of oxalic acid gives a ‘sour’ taste to the plant (Christenhusz and Byng
2016).
