Stone (Fl. Cambodge, Laos & Vietnam 20: 40. 1983) considered Pandanus forceps to be a synonym of P. kaida. Stone (Ceylon J. Sci., Biol. Sci. 11(2): 119. 1975) noted that P. kaida currently is known only in cultivation. The plants sometimes are used for hedges or living fences, and the young shoots are edible.
