    Acrostichum tambillense Hooker, Icon. pl. 7: t. 656. 1844. Type. Ecuador. Tambillo, Jameson s.n. (K!; isotype P!). Acrostichum pallidum Baker ex Jenman, J. Bot. 17: 263. 1879. Elaphoglossum pallidum (Baker ex Jenman) Christensen, Index filic. 312. 1905. Type. Jamaica. Jenman s.n. (K!; isotype NY!). Elaphoglossum tambillense is very close to E. erinaceum but can be distinguished by its nearly glabrous blade margin and narrow, dark maroon rhizome scales.
