Alsophila dimorpha, synonym Cyathea dimorpha,[1] is a species of tree fern native to central and southeastern Sulawesi, where it grows at an altitude of 120–1700 m. The trunk is erect and 3–4 m tall. Fronds are pinnate to bipinnate and up to 2 m long. Fertile pinnules are reduced in size. The stipe is short and bears basal scales. The scales are narrow, glossy, dark and have pale edges. Indusia are absent.[2]
The specific epithet dimorpha refers to the strong morphological differences between fertile and sterile pinnules. Sterile pinnules are larger, while fertile pinnules are narrow, reduced and lobed.[2]
