Prepared by Gronovius using findings supplied by Clayton and printed without his knowledge (but with attribution). First published in two volumes in 1739 and 1743, respectively. A second printing containing both parts also appeared in 1743. Clayton prepared an expanded edition that never appeared, in part because it was preempted by a 1762 expanded edition published by Gronovius’s son Laurens Theodorus Gronovius, entitled Flora Virginica exhibens plantas, quas nobilissimus vir D. D. Johannes Claytonus, Med. Doc. etc. etc. in Virginia Crescentes observavit, collegit & obtulit D. Joh. Fred. Gronovio. In 1812, APS vice president Benjamin Smith Barton set out to publish an updated edition in four parts entitled, Flora Virginica: sive plantarum, praecipuè indigenarum, Virginae historia inchoate, but only the first part appeared. The original text included a map depicting Clayton’s travels.
