In the past few decades several different species of the genus Oxalis have been recorded as new to Belgium. Horticultural activities play an important role in the introduction and local dispersal of both cultivated species (as garden escapes) and weeds. A key for the identification of twelve species is followed by brief comments. Particular attention is drawn to gaps in the present state of our knowledge: distribution and status in Belgium, morphological variation within certain species, and identification problems.
