|discussion=<p>H. A. Gleason and A. Cronquist (1963) and L. J. Uttal (1974) considered <i>Spiraea corymbosa</i> to be a variety of S. betulifolia. K. Sax (1936) found <i>S. corymbosa</i> to be a triploid with complete pollen sterility and hypothesized that it must exist as a diploid, or form viable egg cells, because it is involved in hybrids. If so, these cytological differences may be correlated with some morphological variation.</p>
