Tennessee: A Novel Hybrid Apomictic Eupatorium (Asteraceae) from the Southern Appalachians

Observations showed that flowers did not produce pollen, and fertile seed was set on bagged heads. Because the plants did not match morphologically any species of Eupatorium, DNA sequences were obtained for the nuclear ITS and plastid trnC-petN regions, following procedures of Schilling et al. A search of specimens at TENN failed to produce any that exhibited the same morphology, and somewhat limited searches of the surrounding geographic area failed to locate any additional plants. [...]at present this plant is known only from a restricted location in a site that has no special edaphic or topological features.
