Johannes Gessner (Swiss, 1709–1790)
From Tabulæ Phytographicæ, analysin generum plantarum exhibentes
When Carl Linnaeus set down his system of scientific classification for all parts of the natural world, at the top were the three kingdoms that many still reference today: plant, animal, and mineral. Within his plant kingdom was the class Pentandria, encompassing plants with five stamens. Swiss scientist Johannes Gessner (1709–1790) was one of the first to adopt the Linnean system. His botanical illustration of the class of Pentandria. reproduced here as a 1,000-piece puzzle, is a plant-lover's delight, and a puzzle-doer's enjoyable challenge.
