Solidago shortii (Asteraceae), Short's Goldenrod, is an endangered species native to Kentucky. This species was described by John Torrey and Asa Gray in 1842 in A Flora of North America. An examination of herbarium specimens of Solidago shortii, including all historical collections that could be located, revealed considerable nomenclatural confusion. Fourteen sheets from five herbaria exhibited six type annotations. In addition, a typification of the species had not been published. The complex nature of the protologue necessitated a consideration of Torrey and Gray's species concept and nomenclatural practices in the context of the International Code of Botanical Nomenclature. On the basis of these considerations, we designate one lectotype and four syntypes for Solidago shortii.
