Alsophila erinacea, synonym Cyathea erinacea,[1] is a species of tree fern native to Mexico, Costa Rica, Panama, Venezuela, Colombia, Ecuador, Peru and Bolivia.[2]
It grows in tropical rain forests, particularly in the understory, and on riverbanks up to the montane zone at an altitude of about 800–2,100 metres (2,600–6,900 ft).[2]
Description
[edit]The erect trunk of Alsophila erinacea is up to 15 metres (49 ft) tall, 7–10 cm in diameter and has black spines. The arching fronds are bipinnate, up to 3.5 m long and form a sparse crown. The rachis and stipe are scaly and may be either straw-coloured or brown to dark brown. The scales are bicoloured, having a dark brown to blackish centre and pale whitish margin, as well as a terminal seta. Characteristically of this species, pinnule veins bear whitish scales with star-shaped setae. Sori are round and form on either side of the pinnule midvein. They are covered by globose indusia.[2]
