Linum harperi Small. Common name: Harper's Grooved Flax. Phenology: Jul-Aug. Habitat: Dry to mesic longleaf pine savannas and flatwoods. Distribution: FL Panhandle, s. GA, and s. AL. The last apparent collection of this taxon was collected from Conecuh Co., AL (A.R. Diamond 13442) in 2002. Specimens from GA (R. Harper) are likely historical, but Godfrey's and Anderson's specimens may point to current extant populations of L. harperi (L. sulcatum var. harperi at varietal rank).
Origin/Endemic status: Endemic
Taxonomy Comments: It is probably distinct from L. sulcatum at the species level (and is treated so here), but needs additional study. Indeed, the taxon should be given conservation priority (G1/T1).
