Alsophila khasyana, synonym Cyathea khasyana,[2] is a species of tree fern. Its natural distribution extends from India to Myanmar, although it is absent from Sri Lanka. A. khasyana grows in forest at an altitude of 1400–1700 m. The trunk of this plant is erect and 5–7 m tall. Fronds may be bi- or tripinnate and 2–3 m in length.
