Dear Arnold; Chen Yi is notorious for substituting and mis-identifying plants especially dormant tubers. Whether this is intentional or accidental is unknown. Your plant is probably either A fargesii or A franchetianum. Some authors consider them both as a single variable species. These are closely related and difficult to identify from an immature leaf such as you show. Adult leaves can be immense- up to 18 inches in length for the central main leaflet. Mature leaves have three leaflets, younger leaves may have a single undivided leaf or one or two divisions of various depth. It is one of the easier and hardier Chinese species and common from Chen Yi regardless of ID # The International Aroid Society has a gallery of photos that might help. Google will bring this up. Best Jim W. ps a new book 'The Genus Arisaema, a monograph for botanists and nature lovers' by G and L Gusman is worth an inter-library loan. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
