Plants terrestrial, sometimes epiphytic. Aerial shoots often clumped, simple proximally, dichotomously branched distally, 3(–several)-ridged. Appendages minute, bractlike, borne distally on ridges of aerial shoots, sterile appendages subulate, those subtending synangia 2-lobed. Synangia ± globose, obscurely 3-lobed.

Distribution

Tropical and warm temperate regions.
