I would here express my obligations to the Geological Survey of New Zealand 
for the loan of the collections described in the present memoir. To the Director of 
the Survey, Mr. P. G. Morgan, F.G.S., I am indebted for his kindness in facilitating the 
loan of the specimens and the publication of this memoir. I wish also to record my 
grateful thanks to Dr. J. A. Thomson, F.G.S., formerly Palaeontologist to the Survey, 
for similar help, and especially for much information relating to the plant localities 
and to the New Zealand literature bearing upon them. The New Zealand Survey 
has also kindly made me a grant towards the cost of the illustrations of this memoir. 
I have also to acknowledge the loan of several private collections from New 
Zealand. The very interesting series of plant-remains collected by the late Mr. J. S. 
Nicol, of Mokoia Farm, near Gore, was originally lent to me a year or two before 
his death. These specimens were subsequently presented by his executors to the Sedgwick 
Museum, Cambridge, where they are much valued. 
Dr. P. Marshall, F.G.S., now of Wanganui(l), and Mr. R. Speight, F.G.S., of Canter¬ 
bury Museum, Christchurch, have kindly allowed me to examine specimens in their charge. 
Mr. Speight has also collected for me a series of plant-remains from the Malvern Hills, 
which he has presented to the Sedgwick Museum, Cambridge. Several of these speci¬ 
mens are of interest, and are figured here. I am particularly grateful to Mr. Speight 
for the trouble he has taken in this matter, and also for kindly forwarding the photo¬ 
graphs of the plant-beds at Mount Potts and in the Clent Hills for reproduction here. 
To Mr. D. G. Lillie, M.A., of St. John’s College, Cambridge, I am indebted for 
information in regard to the plant localities which he visited when in New Zealand, 
and especially for notes on the fossil forest of Waikawa. I -am also under great 
obligations to him for obtaining for me the loan of specimens in New Zealand. Dr. L. 
Cockayne, F.R.S., has also kindly sent me copies of his photographs of the fossil forest 
at Waikawa, which are included here. 
The photographs reproduced in the plates are the work of Mr. W. Tams, and 
the drawings, of Mr. T. A. Brock, both of Cambridge. The sketch-maps were drawn by 
the late Mr. Edwin Wilson. I am indebted to all three artists for the skill and 
trouble which these illustrations represent. 
Lastly I would endeavour to express my sincere thanks to my friends in Stock¬ 
holm, Professor Nathorst and his assistant Dr. Halle, to whose exceptional knowledge 
of Mesozoic plants I have appealed in several cases of difficulty. Professor Nathorst 
has very kindly interested himself in no small degree in these matters, and to his 
sound advice and wide knowledge I am particularly indebted. Thanks to his kindness, 
I have had an opportunity of comparing many of the New Zealand Specimens here 
described with the rich series of Mesozoic floras of Antarctica and South America, 
as well as those from other localities, preserved under his care in that great “ Mecca ” 
of Palaeobotany at Stockholm.
