It grows in mossy forest up to an altitude of about . ==Description== The trunk of ''Cyathea ferruginea'' is erect and tall. Fronds are bi- or tripinnate and up to in length. The stipe bears short spines and sparse scales, which are dark brown in colour and have pale, narrow, fragile edges. Sori occur near the fertile pinnule midvein and are covered by thin, pale indusia.
