This species is related to Malva parviflora L. in the fasciculate and short pedicelled flowers, and to Malva microcarpa Pers. in the smaller fruits. However, it may readily be differentiated from Malva parviflora L. in its smaller fruits, less enlarged, papery calyx enclosing the fruits. While it differs from Malva microcarpa Pers. in its fasciculate, compact flowers and calyx enclosing the fruit. Pedicels and fruiting calyx of this species which become whitish after drying are also important characters to distinguish from both the species Malva parviflora L. and Malva microcarpa Pers.
