Inflorescence bracts tightly sheathing; fruits pedicellate, ellipsoid, to 2 cm long and 1 cm diameter, yellowish-brown. (W.J.

The type of C. formosanus, and the illustration and description of Beccari (1908, 1913), show a palm with irregularly arranged, distantly spaced, broadly lanceolate pinnae, and the rachis ending in a cirrus. This is identical with the isotype of Calamus quinquesetinervius and an image of the type and illustration of C. orientalis. Calamus formosanus was placed by Beccari (1908) in Group XV, and appears to be a member of the C. palustris group of species. (W.J.
