The Mesozoic Flora of Graham Land 
by 
T. G. HALLE. 
With 9 plates. 
Introduction. 
One of the most important results of the Swedish Antarctic Expedition igoi — • 
1903, under the direction of Professor O. Nordenskjöld, was the discovery, made 
by Professor J G. Andersson, of a rich Mesozoic flora at Hope Bay, Graham Land. 
The rich material collected at this locality was handed over for examination to Pro- 
fessor A. G. Nathorst, together with all other fossil plant-remains brought home by 
the expedition. Already in 1904, Professor Natiiorst published a first preliminary 
report on the whole collection of fossil plants, and the Tertiary flora has since been 
examined and described in detail by other palæobotanists. Professor Nathorst 
intended to work out the Mesozoic flora himself, but was prevented, by other ur- 
gent work, from so doing. He then proposed to hand over the material to me, and 
after some hesitation I accepted this kind offer. It should be borne in mind that 
the collection had, before I took it over, been preliminarily examined by Professor 
Nathorst, who had identified the more important forms and who had also given 
an account of the general character of the flora in the report mentioned. During 
the progress of my own work I had further the good fortune to receive from him 
all possible help and encouragement, for which I desire here to express my deep 
gratitude. For advice in matters of nomenclature, I am indebted to Professor C. 
A. M. Lindman. My thanks are further due, for much valuable information, to Pro- 
fessor J. G. Andersson, who brought together this interesting collection under 
severe hardships.
