Annuals (sometimes perennials in S. frondosum); taprooted. Stems usually branched. Heads radiate or disciform. Ray (or pistillate) florets more numerous than disc florets, in 2–5+ series (corollas reduced to narrow laminae or to tubes). Disc corollas barely ampliate, lobes erect. Pappi longer than disc florets at flowering. x = 7.
Distribution
North America, nw Mexico, Eurasia.
Discussion
Species 3 (3 in the flora).
A. G. Jones (1989) segregated Brachyactis from Aster in a broad sense. Recent molecular phylogenetic analyses (J. C. Semple et al. 2002) do not support this relationship, species of sect. Conyzopsis clearly belonging in Symphyotrichum.
