Description
Alsophila imrayana is a species with an erect trunk that is 8–10 metres (26–33 ft) tall and 10–15 centimetres (3.9–5.9 in) in diameter. It is covered with sharp, blackish spines and pale brown hairs. Fronds are bipinnate, 2–3 metres (6.6–9.8 ft) in length, and occur in whorls of five. The crown is large and spreading, especially in young plants. The rachis and stipe range in colouration from brown to dark brown and bear bicoloured scales (brown centre and paler margin) with a terminal seta. Scales on pinnule veins are whitish. Sori are round and borne on either side of the pinnule midvein, towards the base of the pinnule segment. They are protected by red-brown, globose indusia. The specific epithet imrayana commemorates plant collector John Imray (1811-1880), who collected the type material.
