Four remarkable images from the 19th-century Austrian botanist Anton Kerner von Marilaun's Pflanzenleben, one of his most important works. Some 20 years after its initial publication in German in 1887 the work was brought to the English speaking world in a translation by F. W. Oliver under the title The Natural History of Plants their Forms, Growth, Reproduction, and Distribution. The images here come, via Wikimedia Commons, from Kurt Stüber's wonderful collection of historical botanical illustrations housed at his BioLib site, definitely worth an explore.
