Description
The trunk of Alsophila ferruginea is erect and 2–4 metres (6.6–13.1 ft) tall. Fronds are bi- or tripinnate and up to 1 metre (3.3 ft) 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.[2]
Large and Braggins (2004) note that the specific epithet ferruginea, meaning "rust-coloured", may refer to the brown scales of this species.[2]
