The illustrator Georg Ehret (1708–1770) also published by subscription. His series of lavish botanical illustrations, Plantae et papiliones rariores, was published plate by plate over a period of ten years. Ehret had often provided illustrations for the publications of other authors, including Linnaeus, but he wished to publish a set of plates of his own design and specifications. Two of the plates contain dedications to individuals who had subscribed: one to the Duchess of Portland and the other, included above, to George Parker, Earl of Macclesfield, who served as president of the Royal Society from 1752 to 1764.
