Flora Virginica exhibens plantas quas v. c. Johannes Clayton in Virginia observavit atque collegit. Easdem method sexuali-disposuit, ad genera propria retulit, nominbus specificis insignivit, & minus cognitas descriptsit.

The first flora of Virginia. As stated on the title page, Gronovius, a Dutch botanist, based this work on specimens collected by the Virginia plant collector and botanist John Clayton. While Clayton supplied the specimens, the final identification of the plants, the science and system of the book were the work of Gronovius.  The second edition of 1762 included a map documenting Clayton's travels.
