Viola renifolia N. Martineau

Usually in cedar swamps; forests and thickets of other conifers as well.

Closely related to V. blanda; both species may have the lateral petals beardless or bearded, although the beard tends to be more pronounced in V. blanda. Leaf pubescence, if present, tends to be more dense in V. renifolia. Collections from a cedar swamp at Round Lake, Emmet Co., have been determined as V. blanda × V. renifolia (C. W. Fallass in 1924, ALBC; E. G. Voss 1885A in 1954, UMBS). Such hybrids are surely to be expected elsewhere and a number of ambiguous specimens may be this.
