|discussion=<p><i>Symphyotrichum dumosum</i> is introduced in New Brunswick. It is widely cultivated. It can hybridize with <i>S. racemosum</i> and <i>S. lanceolatum </i>var.<i> interior</i> (A. G. Jones 1989). G. L. Nesom (1994b) and J. C. Semple et al. (2002) recognized several varieties within the complex: <i></i>var.<i> dumosum</i> [syn. <i>Aster</i> coridifolius Michaux, A. dumosus Linnaeus var. coridifolius (Michaux) Torrey & A. Gray]; var. gracilipes (Wiegand) G. L. Nesom (syn. A. dumosus var. gracilipes Wiegand); var. pergracile (Wiegand) G. L. Nesom (syn. A. dumosus var. pergracile Wiegand); var. strictior (Torrey & A. Gray) G. L. Nesom [syn. A. dumosus var. strictior Torrey & A. Gray, A. dumosus var. dodgei Fernald, <i>S. dumosum</i> var. dodgei (Fernald) G. L. Nesom, the latter possibly the hybrid <i>S. dumosum</i> × <i>S. boreale</i> fide G. L. Nesom 1997]; and var. subulifolium (Torrey & A. Gray) G. L. Nesom (syn. A. dumosus var. subulifolium Torrey & A. Gray). Some of these taxa may deserve higher rank. More work is needed in the complex, however, before a coherent taxonomy can be achieved.</p><!--
--><p>G. L. Nesom (1997) recognized also a southern pine flatwoods entity called <i>Symphyotrichum</i> kralii G. L. Nesom, based on the illegitimately named <i>Aster</i> pinifolius Alexander (not Nees, nor F. Mueller). The type of A. pinifolius, however, appears to be conspecific with that of <i>S. simmondsii</i>. At present, it seems best to wait for full investigation before formally recognizing such taxa.</p>
