Rose flowers. 17th century artwork of four rose (Rosa sp.) plants and their flowers. A yellow rose (lower right), red rose (upper right), Scotch rose (Rosa spinosissima, upper left) and cinnamon rose (Rosa cinnamomea, lower left) are seen. Artwork from Basilius Besler's Hortus Eystettensis (1613). This book illustrated over 1000 flowers, attempted an early pre-Linnaeus taxonomy and was the largest and most comprehensive work of its time.
