Grammitis diminuta

 Grammitis diminuta is a fern in the family Polypodiaceae. The specific epithet comes from Latin "diminutio" (to decrease or diminish), with reference to the tapered frond base.
Description.
The plant is an epiphytic fern. It has a stout, erect rhizome with light brown, lanceolate scales. Its simple fronds combine a short stipe with a narrowly elliptic lamina 3–15 cm long and 0.4–0.8 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.
