 Chrysopsis (Nutt.) Ell.

The Eastern or Florida Goldenasters are members of the genus Chrysopsis (Compositae: Astereae).  All species have flagelliform hairs with one to several large basal cells and several long thin end cells.  Achenes have a quadruple to triple pappus (Semple 2006), some fruit bodies have red-brown translucent ridges.

All nine species are herbaceous perennials native to Florida (map; seven species are x = 5 diploids). Two species (both polyploids) also occur in other parts of the southeastern United States (C. mariana an x = 4 species with 2x, 4x, 6x, and 8x races; and C. gossypina, an allopolyploid with x = 9). Semple (1981) monographed the genus, but several new species were described recently (Delaney & Wunderlin 2002; Delaney et al. 2003). Chrysopsis pilosa was transferred to Bradburia (Semple 1996).  Recent DNA work indicates that Chrysospsis is monophyletic and closely related to Bradburia (Brouillet et al. 2009). The treatment here follows Flora North America (Semple 2006).
