both in species and in individuals. In Westland they occur for the most 
part as epiphytes, clothing the trunks and overhanging boughs of the trees 
in sheets with their delicate drooping fronds, ranging from the forest-floor 
to the tops of the highest trees, and being distributed throughout the entire 
district from the coast-line to the subalpine zone. The suggestion to study 
the Hymenophyllaceae was made to me by Dr. L. Cockayne, F.R.S., some 
six or seven years ago, on my first going to live in Westland ; and I have 
to thank him for many suggestions with regard to the scope of my work. 
Since then I have been able to examine thoroughly practically the whole 
of north Westland, as well as to see something of the forests farther south. 
My account of the Hymenophyllaceae as they here occur will be found, 
I think, to be fairly complete. I have also been able personally to study 
the family in the southern-beech and other forests of both Canterbury 
and Nelson at many selected places, and to trace its distribution in the 
Auckland District. ‘
