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, 
arc 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.
