Discussion

  • This species is known only from the Philippines, and just reaches Taiwan on Lanyu Island. It is very variable morphologically, and six varieties are recognized (Lapis, 1987). The Taiwan plants were placed, without discussion, in var. sublevis Becc. by Chang (1988). (Henderson, A.J., A New Species of Calamus (Palmae) from Taiwan in Taiwania 50(3). 2005)A
