Remarks.

A common temperate species in the central and south regions of Chile from Coquimbo Region to at least the Los Lagos Region but absent from colder subantarctic climates. It also occurs in Australia and New Zealand ( Spence and Ramsay 2019). The species is found on exposed to partially shaded damp to drying soil, sand, and rock ledges, often in open woodlands or on cliffs and outcrops. The species is characterized by dioicous sexual condition, medium-sized imbricate golden to yellow-green strongly concave leaves, a costa excurrent in a long often denticulate awn, a weak or nearly absent limbidium distally, serrate distal leaf margins, and the absence of rhizoidal tubers (Illustrations: Spence and Ramsay 2006: 335, as R. campylothecium ; Fife 2015: 85, as R. campylothecium ).
