Ohs . This Fern in its native forests, presents a very grace- 
ful appearance. It there attains a large size, some fronds 
having been observed between two and three feet in length. 
The fertile fronds, generally three in number in each plant, 
are invariably very erect, ascending directly from the centre ; 
while the numerous barren fronds spread out horizontally in a 
half-procumbent manner, enchant the eye of the observer 
with a most elegant circle of delicate and ever-living green. 
A smaller variety of this species was also detected in allu- 
vial soil, in the low woods in the first day’s journey from 
Turanga towards Waikare.
