Zamia roezlii is a species of cycad, a plant in the family Zamiaceae. It is found in Colombia (Choco, Nariño, Valle del Cauca, and Amazonas departments) and the Pacific coast of Ecuador. It is named for the Czech botanist Benedikt Roezl. A single sperm cell from Zamia roezlii is about 0.4 mm in length and is visible to the unaided eye, being the world's largest plant sperm cell. Drosophila bifurca, a species of fruit fly, has sperm that are 5.8 cm long, albeit mostly coiled tail.[2]
