Gymnosphaera khasyana, synonyms Alsophila khasyana and Cyathea khasyana,[2] is a species of tree fern. Its natural distribution extends from the Himalayas and eastern India to Myanmar and south-central China, although it is absent from Sri Lanka. G. khasyana grows in forest at an elevation 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. G. khasyana has a long, dark stipe that is covered in numerous scales. These scales are dark and have broad, pale, fringed edges. Sori are borne near the midvein of fertile pinnules and lack indusia.[3]
The specific epithet khasyana refers to the Khasi Hills of India.[3]
