It is covered with sharp, blackish spines and pale brown hairs. Fronds are bipinnate, Script error: No such module "convert". in length, and occur in whorls of five.

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.[2]
The specific epithet imrayana commemorates plant collector John Imray (1811-1880), who collected the type material.[2]
