ⓘ Alsophila bryophila

Alsophila bryophila, synonym Cyathea bryophila, is a species of tree fern native to Puerto Rico, where it grows in the understory in wet montane and mossy forest at an altitude of 750–1200 m. The trunk is erect, up to 7 m tall and about 10 cm in diameter. Fronds are pinnate or bipinnate and grow to 2 m in length. The underside of the rachis is pubescent and has occasional scales towards the base. The scales range in colour from brown to bicoloured. Sori occur along each side of the pinnule midvein and are covered by scale-like indusia. A. bryophila is a slow growing species, reportedly only increasing in trunk height by 5 cm a year, a growth rate more akin to that of Dicksonia species. It has been estimated that plants may live in excess of 150 years.

Closest relatives appear to be A. bryophila Alsophila brooksii, hotteana Alsophila and small.

Bryophila specific epithet, meaning "kind of love", refers to the fact that this species is often found in mossy forest.

A. bryophila can be cultivated, although it requires a constantly cool and moist conditions to do well. This, apparently, is more susceptible to insect damage than most other species. In the horticultural trade, A. bryophila often mistakenly called "waterfall cyathea fluffy," although this is a synonym for an unrelated species of Alsophila auneae.
