Horrowav.—Studies in the New Zealand Hymenophyllaceae. 579 
The — photographs were the work of Mr. C. Beken, hs Christ- 
church, and were taken from specimens in my own collection These 
illustrations may be regarded as typically showing the species as they occur 
in Westland, у the exception, of course, of those which I have not been 
able to find the Mr. Т. Е. Cheeseman, F.L.S., has informed me that 
they well багі also the form shown by the species in the deep e 
of the wet districts of the North Island, dier that he sees no indica 
of distinct geographical races. I am greatly indebted to Mr. domsaga 
who has on many occasions generously placed at my disposal his knowledge 
of the distribution of the Hymenophyllaceae in many parts of New Zealand. 
I have to thank also the Director of the Government Meteorological Depart- 
ment for kindly supplying me with the rainfall and other meteorological 
data included in this paper. Finally, it gives me much pleasure to acknow- 
ledge the kind invitation extended to me by the Director and the Chief 
of the Biological Department of the Cawthron Institute at Nelson to carry 
on my work at the Institute during the six months that I was in that 
district, an invitation of which I fully availed myself.

I. List or THE SPECIES. 
The following is the complete list of twenty-seven species which occur 
in the New Zealand Biological Region (see map 1), all of which, it may be 
added, are present on the main islands of New Zealand. The ten which, 
so far as is known, are endemic are indicated in the list by asterisks. For 
this information I am indebted to Mr. Cheeseman. For the full systematic 
description of the species reference must be made to the Manual of the New 
Zealand With the exception of H. ciliatum, whose existence in 
New Zealand is doubtful, all are illustrated in the present paper from — 
phs, the numbers in square brackets in the list corresponding to 
number of the plates on which each species will be found. In Ко 
with the rules of priority in nomenclature the specific names of four of the 
species will be found to differ from those given in the Manual. Other plants
