THE JURASSIC FLORA (CoxTixtED). 



rilK JITKASSIC FLORA OF OltKlJOX. 



A sufficiently full account of the expedition made in 1899 to the 

 Buck Mountain region of Oregon, as also of previous studies of and col- 

 lections made in that region, was given in the first paper." As stated 

 there, all the specimens that had ever been sent to Washington, including 

 our large collection of that season, and the collections made by Mr. Storrs 

 during previous years, were sent to Professor T'ontaine foi' elaboration, 

 and their study had been begun by him before tliat paper went to press. 



Buck Peak 



It was completed in tlie spring of 19U1, and Professor Fontaine's report, 

 including descriptions of the species and careful indications relative to 

 the illustrations, was sent on in April. The types have now all been 

 figured, a new process (the Williams process) having been employed. It 

 therefore only remained foi' me to prepare the report for publication. 

 The following paper is essentially the report of Professor F'ontaine, only, 

 as in former cases, it has been necessary for me to prepare the synonymy 

 of the previously described species and attend to the systematic arrange- 

 ment. This, therefore, and a few footnotes, to which my initials are 

 attached, are the only parts for which I am responsible. The accom- 

 panying sketch map of the region and section, prepared by Mr. J. S. 

 Diller, will make the geographical and stratigrajihical relations clear.
