Note.

Phlegmariurus copelandianus is a rare species that is endemic to Indonesia where it is an epiphyte in montane rainforest. It was placed in the group of the New Guinea endemic P. macgregorii (Copel.) A.R.Field & Bostock by Øllgaard (1989), but does not appear to have a close relative and has not yet been placed in molecular phylogenetic analyses. It is unique among Phlegmariurus in having minute, distinctly petiolate, almost spoon like leaves with a cupped apex and reflexed lateral margins.
