of the page where Balduina is described, we find the footnote: John Torrey and Asa Gray changed Balduina to Baldwinia in 1840, but this orthographical variant was not generally accepted. Balduina is now a conserved name. Balduina is a genus of three species native to the Atlantic and Gulf coastal plain. Not all authors have put them in one genus and they have had various names, but a revision of Asteraceae in 2007 placed all three of these species together in Balduina. Several species of plants have been named for William Baldwin. Among those names that are still in use, we have, including authors, the following names: Eleocharis baldwinii (John Torrey) Alvan Wentworth Chapman, Rhynchospora baldwinii Asa Gray, Saccharum baldwinii Curt Sprengel, Clematis baldwinii John Torrey and Asa Gray, Paronychia baldwinii (Torrey and Gray) Eduard Fenzl and Wilhelm Walpers, Eryngium baldwinii Curt Sprengel, Vernonia baldwinii John Torrey, Xyris baldwiniana Josef Schultes, and Matelea baldwyniana (Robert Sweet) Robert Woodson. At least six other plants, including Fimbristylis annua, Dichanthelium ensifolium, Ptelea trifoliata, Silene catesbaei, Symphyotrichum undulatum, and Viguiera (Rhysolepis) anchusifolia have had names that honored Baldwin, but these are no longer in use.
