This plant only just gets into California NW of Crescent City but occurs from Oregon to Alaska and elsewhere. It was growing in a wet open area among sedges and other vegetation. It looks similar to Viola adunca, which is more common in the same area. The flower size is a little larger and there is a slight difference in color, but a key distinguishing feature is that V. langsdorffii has a glabrous style head, as can be seen here at high resolution, whereas V. adunca has a bearded style head.
