Varieties[1]
Viola primulifolia var. occidentalis A.Gray Viola primulifolia var. primulifolia

It is a low, stemless perennial that produces white flowers in the spring.^[6] It can be distinguished from the similar-looking Viola lanceolata and Viola blanda by its leaves that are ovate, with rounded to truncate bases, and are 1.5-2 times as long as wide.^[5]

While typical Viola primulifolia occurs in a large area of the east, a variety of this species occurs in a small area of the Klamath Mountains in northwestern California and southwestern Oregon, under the name of V. primulifolia var. occidentalis.^[7][8] These populations, which are considered rare and highly localized, have alternatively been referred to as Viola lanceolata ssp. occidentalis.^[9]
