A very beautiful species, having a broad and crisped wing on its 

 rhachis and the upper half of the terete stipe, which, together with 

 the three or four times pinnate fronds, averages from 8 to 10 inches 

 in length, the latter usually twice as long as the former. Sori seated 

 on the tips of short lacinise near the point of the pinna. Indusium 

 orbicular and divided into two valves down to the base; the valves 

 convex and entire. According to Sir William Hooker this is closely 

 related to the K crispatum of Wallich.

The figure of H. nitens in the Icones Filicum is a very charac- 

 teristic representation of our Feejee plant. The New Zealand plant 

 is much smaller ; the fronds ovate and cordate at the base. In both 

 the rhizoma and stipe are pilose.
