Asplenium confusum

A little-documented spleenwort of Indochina, described by Tardieu and Ching in 1936 and known from only a handful of wild records in northern and eastern Thailand and Vietnam. Treat it as a shade fern of seasonally dry monsoon hill forest: warm, humid summers and a cooler, drier winter.

Where it grows wild

No habitat description was reachable; the records sit in monsoon hill forest of northern Thailand and the Vietnamese highlands. Like most Asian Asplenium of this zone it is most likely a shaded terrestrial or rock-dwelling fern on forest slopes.

Recorded at 700–1186 m, median 1175 m; one coastal record without a usable elevation pulls the measured climate slightly warmer.
