Notes
Fee cited Cuming 193 as type, but his description differs considerably from all specimens of Cuming 193 which I have seen (BM, K, P, US) in scales and in size and shape of fronds; as Copeland has stated (Fern Fl. Philip, p. 278) Fee's description would better fit E. callifolium. The specimen from which Fee prepared his description has not been found at Paris. I therefore regard Fee's name as of doubtful application, and have referred all specimens of Cuming 193 which I have seen to E. luzonicum Copel.
