Alsophila caudata

Alsophila caudata, synonym Cyathea caudata, is a species of tree fern native to the islands of Luzon and Mindanao in the Philippines, where it grows in montane forest. The trunk is erect and up to 4 m tall or more. Fronds are bi- or tripinnate and 1–2 m long. The stipe is warty and covered with dark, narrow, glossy scales. Sori are borne near the midvein of fertile pinnules and are protected by firm, brown indusia.
The closest relatives of "A. caudata" appear to be the smaller "Alsophila edanoi" and "Alsophila heterochlamydea". Further study is needed to determine whether all three should be retained as separate species.
