Monarda species 2 [=arkansana] . Arkansas Horse-mint. Phen: Jul-Oct. Hab: Dryish woodlands over calcareous or mafic rocks. Dist: C. and s. AR south nw. LA and ne. TX; disjunct eastwards in n. GA and sw. NC. McClintock & Epling (1942) map and discuss this taxon as endemic to AR and immediately adjacent TX, but mention that "a specimen collected near Columbus, Polk County, North Carolina (Townsend, 1897) is scarcely different from subsp. arkansana". Scora (1967) treats var. arkansana as similarly endemic, though he cites (but does not map) a specimen from Cherokee County, GA and annotated (following the publication of his paper) a later collection from Polk County, NC as var. arkansana. The Polk County, NC material is manifestly var. arkansana and might be considered merely aberrant or a chance introduction, were it not for its repeated collection and the phytogeographic interest of the Blue Ridge Escarpment of Polk County, which harbors several Ozarkian and other Midwestern disjuncts, such as Melanthium woodii.
Origin/Endemic status: Endemic
Taxonomy Comments: Sammons (2011) determined that this entity warrants specific rank; the name is unpublished, however.
