This subspecies differs from Fioria vitifolia L. ssp. vitifolia in the density of indumentum and leaf incision. In the present subspecies the stem and leaves are usually densely stellate pubescent. Leaves entire to shallowly 3-7 lobed. While in Fioria vitifolia L. ssp. vitifolia the stem and leaves are usually sparsely pubescent. Further, the leaves are commonly deeply 3-7 lobed.
