Discussion
Equisetum ramosissimum subsp. ramosissimum apparently was introduced from Europe with ballast (R.L. Hauke 1979). Equisetum ramosissimum subsp. debile (Roxburgh) Hauke occurs in southeast Asia and the southern Pacific Islands. Where the ranges of the two subspecies overlap, fertile, morphologically intermediate individuals are found (R. L. Hauke 1963).
