Description

Pyrrosia angustata is a type of fern belongs to the family Polypodiaceae. The genus Pyrrosia is derived from Greek word, pyrrho meaning reddish; meanwhile, the species epithet is derived from the Latin word means narrowed, which is referring to the narrowing of the lamina in the fertile fronds.

Pyrrosia angustata has long-creeping rhizomes, with around 1.5-2.6 mm thick. The fronds are dimorphic and stalked. The fertile fronds with stipes can reach up to around 25 cm long, while the sterile fronds with stipes can reach up to around 9 cm long. The sori are clearly arranged in a single row between costa and margin. The shape of the sori are elongate, which is 5 mm or longer, and slightly sunken.

The distribution of Pyrrosia angustata is ranged from Peninsular Thailand to Maluku, including Malaysia. It can be found growing in sheltered habitats on tree trunks and on canopy branches, sometimes lithophytic on granite, or terrestrial on sandy ground, and on road embankments at forest margins. Its conservation status is Least Concern in Peninsular Malaysia (Hovenkamp, 2013).
