Botanists today recognize two subspecies. The type subspecies, E. ramosissimum subsp. ramosissimum, is native through much of Asia, Europe, and Africa, with an introduced population in the southeast United States. E. ramosissimum subsp.debile, sometimes treated as the separate species E. debile, is found in extreme southern China, southeast Asia and some Pacific islands, including the East Indies, New Caledonia and Fiji among others. The type subspecies has more obvious branching from the aerial stem than subspecies debile.[3] E. r. subsp. debile is one of the largest forms of Equisetum reaching a height of 9 m (30 ft).[4]
