Alsophila junghuhniana, synonymCyathea junghuhniana,[1] 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.[2]
Large and Braggins (2004) note that A. junghuhniana has been confused with Alsophila crenulata (syn. Cyathea raciborskii), "from which it differs in several characteristics, including larger pinnae". Stipe outgrowths are present in A. crenulata, but absent from A. junghuhniana.[2]
