Oxalis pes-caprae f. pleniflora (Lowe) Sunding (Oxalidaceae), a naturalized invasive alien is recorded for the first time from Turkey. It has staminodes and double petals as different properties from Oxalis pes-caprae L. Sympatric variations occured in the species populations could be the result of an accumulation of mutations or genome rearrangement. Invasive alien weed Oxalis pes-caprae and its infraspecific forma pleniflora are illustrated in photograps and the geographical distribution in Turkey is mapped.
