● Creeping on moss-covered tree trunks. Guangdong, Hainan.

One of us (Mickel) is doubtful of a close relationship between Elaphoglossum luzonicum and E. mcclurei such as to make them conspecific and notes that E. luzonicum has lanceolate scales at the lamina margin and abundant broad scales on the stipe, whereas E. mcclurei has only stellate trichomidia (minute hairs) on the lamina (lacking in E. luzonicum) and narrowly lanceolate stipe scales.
