DistributionThe SERNEC database (as of June 2020) contains no specimens labelled as Rudbeckia triloba var. rupestris, but Weakley (2022) indicates it is common in the NC Mountains; and the NC NHP lists it as a Watch List taxon with a state rank of S1, occurring in "forests at high elevations", with only Mitchell County named.

Restricted to mountains of KY, NC, and TN.
AbundancePresumed very rare, but really the editors have no idea of its current status. The NCNHP recently (2024) changed the State Rank from S1 to now SH, and the Status from W7 to now SR-T, as a tracked taxon.
HabitatNo data.
PhenologyNo data.
IdentificationAccording to the key in Weakley, this variety has leaves that are 3-lobed or without lobes (vs. at least a few leaves 5-7 lobed in var. beadlei. It differs from var. triloba in having longer rays and a wider disk.
Taxonomic CommentsThe taxonomic status of the varieties is not yet settled.
