|discussion=<p>Variety carlottae is known from the Queen Charlotte Islands and the Brooks Peninsula of Vancouver Island, British Columbia. It is reported to hybridize with <i>V. glabella</i> (G. W. Douglas et al. 1998–2002, vol. 5).</p><!--
--><p>One of the characteristics used by Calder and Taylor to distinguish <i></i>var.<i> carlottae</i> was the presence of a prominent purple stripe on the sepals. V. B. Baird (1942) reported that sepals of <i></i>var.<i> biflora</i> plants in Colorado occasionally have one purple line down the center. Purple midveins are also reported on sepals of <i></i>var.<i> biflora</i> in Taiwan (Hsieh C. F. 1977). Some herbarium specimens at UC identified as <i></i>var.<i> carlottae</i> from the Queen Charlotte Islands do not have a purple midvein or stripe on the sepals. The presence of a purple midvein or stripe on the sepals should not by itself be used to make a determination of <i></i>var.<i> carlottae</i> in areas other than the Queen Charlotte Islands and Vancouver Island.</p><!--
--><p>Floras that discuss the capsules of <i>Viola biflora</i> report that the surface is glabrous. One exception is G. W. Douglas et al. (1998–2002, vol. 5), where the capsules of <i></i>var.<i> carlottae</i> in British Columbia are described as sparsely short-hairy.</p>
