Alsophila caudata, synonym Cyathea caudata, [1] 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. [2] As of April 2022, Plants of the World Online treated it as a synonym of Alsophila speciosa. [3]

Taxonomy

The species was first described, as Cyathea caudata, by John Smith in 1841. As of April 2022, World Ferns accepted the species as Alsophila caudata, [4] whereas Plants of the World Online treated it as a synonym of Alsophila speciosa. [3]

In 2004, it was said that the closest relatives of A. caudata appear to be the smaller Alsophila edanoi and Alsophila heterochlamydea . Further study was needed to determine whether all three should be retained as separate species. [2]
