Arisaema triphyllum ssp.stewardsonii (Britton) Hutt. Editorial comment: Who in their right mind would put A. stewardsonii in the same species as A. triphyllum? Give me a break, it's a radically different plant. It blooms a month later, grows in different conditions, and dammit, it looks much different. This would never happen in China....'Nuff said.
