Flowers violet-purple, 2-2.5 cm wide; lower 3 petals bearded; style dilated upwards, capitate, with a conic beak on the lower side, the stigma within the top of the beak; cleistogamous flowers on erect or ascending peduncles. Fruit ovoid; seeds brown.

Notes

Flowers mid April to late June

Wetland indicator: FACW

Variety ovata (=Viola fimbriatula) is more northern and has leaves that look similar to var. sagittata early in the year but the mid-season leaf blades are more truncate or somewhat cordate at the base. It also has sepals that are ciliate (vs. eciliate in var. sagittata). The following images are of var. ovata taken in northern NY in September.
