LARAMIE FLORA OF THE DENVEE BASIN. 



result is yet or ever will be entirely free from 

 errors of the kind detailed above. This should 

 not be interpreted, however, as meaning that 

 all the older work was uniformly of poor 

 (juality, for it was not, but it was pioneer work, 

 with all the handicaps incident to such work, 

 and as such it is to be judged. Whether good 

 or bad, it is the foundation upon which all 

 subsequent effort must be built. 



SYNONYMS AND CHANGES OF INTERPRETATION. 



During the half century that the flora of 

 the Laramie formation has been under consid- 

 eration by geologists and paleontologists it has 

 naturally happened that there have, been many 

 changes in nomenclature and in interpreta- 

 tion. As the literature is more or less widely 

 scattered and difficult of consultation, I have 

 thought it might be of use to have all these 

 changes brought together. The users of this 

 literature will have no difficulty in noting and 

 collating the changes that have taken place by 

 consulting the following alphabetically ar- 

 ranged list:,
