Discussion
Of conservation concern.
Rudbeckia nitida grows in northern Florida and southern Georgia (a report for Alabama has not been confirmed). It is cultivated as an ornamental. According to R. Kral (1983), it is threatened or endangered and is associated with savanna or bog dicots and monocots, particularly Eriocaulon, Sarracenia, Lachnocaulon, Rhexia, Xyris, and the composites Coreopsis, Helianthus, and Liatris.
