This is a critically endangered fern that is presently found at three locations at Pulau Tekong and parts of Western Catchment area (Lok et al., 2009). It is naturally found on slopes or cliffs, in forests or facing the sea. It spreads vegatatively via long creeping rhizomes, allowing it to carpet an entire area. Together with its habitat preference, the leaves are also immediately identifiable with deeply lobed fronds bearing serrated margins.
