Cyathea junghuhniana is a species of tree fern native to southern and central Sumatra and western Java, where it grows in forest at an altitude of 1000-2000 m. The trunk of this species is erect and may be 2 m tall or more. Fronds are tripinnate and up to about 3 m long. The stipes of this species are persistent and form a skirt around the trunk. They are brown, spiny, and covered with glossy, dark brown scales. Sori are borne near the midvein of fertile pinnules and are protected by thin indusia.
Braggins and Large (2004) note that C. junghuhniana has been confused with Cyathea raciborskii, "from which it differs in several characteristics, including larger pinnae". Stipe outgrowths are present in C. raciborskii, but absent from C. junghuhniana.
The specific epithet junghuhniana commemorates German botanist Friedrich Franz Wilhelm Junghuhn (1809-1864), who collected numerous plants on Java and Sumatra.
