Tectaria singaporiana is a common fern in the Bukit Timah and Central Catchment Nature Reserves. At the former, it is especially abundant along slopes adjacent to the main trails.The form consists of just a tuft of fronds from a point. The fronds have distinct and depressed secondary and tertiary veins, the latter running perpendicular to the former. The stalk is thin and black.
