Exhibens Ranunculaceas, Dilleniaceas, Magnoliceas, Anonaceas et Menispermeas
This is a botanical plate book, Exhibens Ranunculaceas, Dilleniaceas, Magnoliceas, Anonaceas et Menispermeas, compiled by Augustin Pyramus de Candolle, Pierre Jean François Turpin and Benjamin Delessert and printed in Paris in 1820 for botanists. The pictures are fine line engravings of single plant specimens with leaves, flowers, fruit and dissected parts labelled with Latin names. A designer could take their clean, even contour lines, sparse hatching and tidy scientific layout as a model for minimal botanical diagrams.
