Grammitis wattsii
Description. The plant is an epiphytic fern. It has an erect or shortly creeping rhizome with dense, chestnut brown, narrow pointed scales. Its simple fronds combine a 0.5–5 cm long stipe with a narrowly elliptic-linear lamina 5–20 cm long and 0.4–1.2 cm wide. Distribution and habitat. The fern is endemic to Australia’s subtropical Lord Howe Island in the Tasman Sea; it is confined to the cloud forest on the upper slopes and summits of Mounts Lidgbird and Gower.
