Zamia roezlii (chigua[3]) is a species of cycad, a palm-like pachycaulous plant in the family Zamiaceae.[2][4] 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.[5] The tree is up to 22 feet (seven meters) in height with fronds up to ten feet (three metres) long bearing leaflets up to twenty inches (fifty-one centimetres) long and six inches (fifteen centimetres) wide.[6]
