Parochetus communis is a prostrate herb, growing up to tall. Its leaves are trifoliate (three-parted, like a clover leaf), with each leaflet being long and similarly wide (exceptionally up to ). The leaflets are cuneate (wedge-shaped) at the base, and notched at the tip, with margins that may be smooth or have minute teeth. The stipules at the base of each leaf-stalk are long and entire (untoothed and undivided).
