Cyathea dimorpha 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 rediced in size. The stipe is short and bears basal scales. The scales are narrow, glossy, dark and have pale edges. Indusia are absent.
The specific epithet dimorpha refers to the strong morphological differences between fertile and sterile pinnules. Steriles pinnules are larger, while fertile pinnules are narrow, reduced and lobed.
