The Swiss Scientist Johannes Gessner (1709–1790) produced a beautiful botanical illustration of Pentandria defined by Carl Linnaeus who 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.
Johannes Gessner’s botanical illustration of the class of Pentandria is reproduced here as a 1,000-piece puzzle. A plant-lover's delight and a puzzle-doer's enjoyable challenge.
