Pityopsis graminifolia (Michaux) Nuttall. Phen: Jul-Oct. Hab: Longleaf pine sandhills, other dry woodlands. Dist: Se. NC south to n. FL, and west to s. MS.

Origin/Endemic status: Endemic

Taxonomy Comments: Semple & Bowers (1985) treat P. graminifolia as encompassing five varieties "that intergrade and hybridize, when the ploidy level is the same" (Semple & Bowers 1985). More recent work by Bridges and Orzell (2018b) and Nesom (2019a) has elevated most of these to species level, as reflected in this treatment. Nesom (2019a) interprets P. graminifolia as mostly corresponding to the plants referred to P. graminifolia var. latifolia by Semple and Bowers (1985) and Semple (2006) in FNA. However, Semple (2019) clearly shows that the type of Inula graminifolia is a small-headed specimen with densely stipitate-glandular phyllaries, consistent with the characters of P. graminifolia var. graminifolia in Semple & Bowers (1985). Pending further study, this name must be used in that sense. This taxon is diploid (2n=18).
