Paxton’s Magazine of Botany
/The Internet Archive has 10+ issues of Paxton’s Magazine of Botany and Register of Flowering Plants published from the mid-1830s into the 1840s. Sir Joseph Paxton was the publisher; he is also known for cultivating Cavendish bananas and designing the Crystal Palace for the Great Exhibition of 1851. The list of links for the volumes available can be found here. Beyond the botanical prints, the issues also are good examples of what was happening with plants during that time. I enjoyed them back in 2013 and include a sample image from the volumes here.
