|discussion=<p>C. T. Frye (2006) found morphologic evidence of introgression between <i></i>var.<i> canadensis</i> and <i></i>var.<i> obovalis</i>; the introgression may have been facilitated by land clearing and other anthropogenic disturbances. Variety obovalis represents a geographic trend towards smaller petal and inflorescence dimensions in the southern range; there is much overlap range-wide. Additionally, characters such as plant height and extent of lateral spread that have been used in major couplets of keys are variable and may largely depend on site disturbance history, for example, mowing, burning. Variety obovalis is self-incompatible and apparently sexual (C. T. Frye, unpubl.) and diploid throughout its range (M. B. Burgess et al., unpubl.). The triploid count (2n = 51) is represented by a single specimen determined by W. A. Robinson and C. R. Partenen (1980).</p>
