a scaly nature. These fronds are simply pinnate (only once divided to the 

 midrib), with fifty to sixty pairs of opposite, short- stalked, narrow -spear- 

 shaped, blunt, straight or slightly sickle-shaped leaflets, the central ones being 

 lin. to IJin. long and the lower ones much reduced ; all are of a somewhat 

 rigid, leathery texture, with their upper surface naked, while the lower is 

 scaly on the midribs. The sori, less conspicuous than in most species, are 

 provided with a very narrow involucre, which is soon hidden. — Hooker^
