DistributionCoastal Plain, Sandhills, and lower Piedmont.

Coastal Plain, southeastern VA to northern FL, eastern TX, and central AR.
AbundanceCommon in Coastal Plain (especially the Sandhills where locally abundant), rare to uncommon in lower Piedmont.
HabitatMoist to wet (sometimes dry) soils of Longleaf Pine-Wiregrass savannas and flatwoods, ecotones of pocosins, blackwater streamhead ecotones, seepage areas, roadside ditches.
PhenologyFlowering and fruiting September-early November.
IdentificationIn general, members of S. rugosa grow 2-4 feet tall (occasionally to 5 or 6 feet according to FNA) and have widely branching inflorescences with heads along one side of each branch. Stems often are connected via horizontal rhizomes and thus form colonies. Stems vary from densely to lightly hairy with coarse short hairs. Basal leaves are absent at flowering time; stem leaves are lance-shaped or elliptic, sessile (without stalk), the tip pointed, margins toothed, and surfaces +- wrinkled ("rugose"), the upper surface rough (scabrous). Upper stem leaves are smaller. In var. celtidifolia, the inflorescence is much more open and widely branching than in var. rugosa, leaf surface is much more wrinkled, thicker textured, and far more scabrous. Some plants are quite similar to var. aspera, but the upper stem leaves are ovate, much reduced in size (vs. elliptical and not much reduced). Also, note the abundant small, ovate leaves of the inflorescence branches.
Taxonomic CommentsThe entities within S. rugosa have been variously treated (or ignored) in the past; our treatment follows that of FNA and Weakley, except we split out the very different S. aestivalis.
