Distribution

USA: AL
Native Distribution: Endemic to Alabama.
Native Habitat: "To date, Hexastylis finzelii is known only from two populations, both from Bishop Mountain in Marshall Co., Alabama. The first of these was discovered in 2019 and serves as the type locality cited above. Upon discovery and initial examination, it was comprised of approximately 125-150 individual plants. The second and much larger population comprised of approximately 1000+ individuals was discovered in 2020 and is about 2 km from the type locality. Both populations occur in the Plateau Escarpment of the Southwestern Appalachians ecoregions seemingly at the boundary of the Pennington Formation and Bangor Limestone geologic units with occasional Pottsville Sandstone debris from above (Griffith et al. 2001; Osborne & Ward 2010). The habitat for both populations is slightly mesic with rocky well-drained soil covered by a regenerated forest several decades old. The forest is mostly of hardwoods, oaks, hickories, sweet gum, and tulip poplar while occasionally cedar and pines are also present. The associated plants do not exhibit any substrate chemistry trend toward acidic or alkaline species likely attributable to the geologic mosaic mentioned above." (Reslit: 3206).
