in Tennessee Clayton explored the Gloucester County region
botanically and in 1734 sent many specimens and manuscript descriptions to the English
naturalist Mark Catesby, who then sent them on to the
Dutch botanist Jan Frederik Gronovius. Clayton would also send work to Gronovius directly. Unprepared for the amount of material sent to him, Gronovius enlisted the help of the Swedish botanist
Carl Linnaeus. Unbeknownst to Clayton, Gronovius would later use much of Clayton's specimen and manuscript work in his 1739 book
Flora Virginica without seeking his permission. Whether or not Gronovius properly credited Clayton in the work is the subject of debate, as some felt that Gronovius greatly downplayed his contributions. A second part of
Flora Virginica was published in 1743 with additional information. Clayton sought to publish his own version of
Flora Virginica but was unable to find a publisher before a second edition of Gronovius's book was printed in 1762. His manuscript is believed to have been lost, likely in a 1787 fire in the
New Kent County clerk's office where the papers were being stored. Clayton's work was also studied by the European botanist
George Clifford and Linnaeus later named a flower in Clayton's honor, a common eastern
North American
wildflower, the spring beauty,
Claytonia virginica.The specimens sent to Gronovius were later collected by
Joseph Banks and the material is now part of the
Natural History Museum in London and makes up the John Clayton Herbarium. ==Honors, death and legacy==
