Edward Johnston Alexander

Edward Johnston Alexander (July 31, 1901 – August 18, 1985) was an American botanist who discovered three species and one genus. He is the author or one of the authors of 205 entries in the International Plant Names Index. He was born in Asheville, North Carolina and studied at North Carolina State University from 1919 to 1923. He was a longtime assistant and curator at New York Botanical Garden (NYBG), originally under the guidance of Small. While at the NYBG, he served as an editor of the Garden's botanical journal Addisonia for about thirty years, until the journal ceased publication in 1964.

Alexander undertook several botanical expeditions in his lifetime, including to Pecos, Texas with John Kunkel Small and to the southern Appalachians and the Rocky Mountains with Thomas H. Everett. His most successful expedition was to southern Mexico from 1944 to 1945. On that trip, he collected around 1,600 specimens and 1,000 seeds and roots for the herbarium and propagation houses at the New York Botanical Garden.
