We endeavour to mobilize in Pl@ntUse historical and botanical illustrations of plants. They allow to testify the presence of a plant in a given place and date, but also to document the evolution of cultivars. Moreover, they are nice to look at.
Most of the illustrations are uploaded in Wikimedia Commons, if it is possible to put them in a CC-BY-SA license, and then imported by a bot into Pl@ntUse. The pages containting whole sets of illustrations are grouped in the Category:Illustrations.
