Flora of the Allegany State Park Region 19 



region especially in spring and early summer and in the 

 late fall will doubtless serve to add considerably to the 

 present list of species. 



The scientific names of the families, genera and species 

 are as a rule those found in the seventh edition of Gray's 

 Manual in order to correlate the names with those of the 

 most convenient manual for use in the field. Where a 

 departure is made from these names, reference is usually 

 made to the place of publication of the reasons for such 

 change, and the name used in Gray's Manual is given 

 in synonymy. Otherwise synonyms are included only 

 where their omission might lead to confusion on the part 

 of those using that manual in the field. 



The names of plants which appear to be native to this 

 region are printed in heavy type, while the names of 

 plants which are naturalized or adventive from some 

 other country or from some other portion of America 

 are printed in light-faced capitals. Synonyms are printed 

 in italics. The common names of the plants are likewise 

 taken from Gray's Manual, supplemented by those used in 

 Wiegand & Eames', Flora of the Cayuga Lake Basin, 

 New York (1926) and from Britton & Brown's Illus- 

 trated Flora (second edition, 1913). 



The authors are under obligation to Carleton R. Ball 

 of the United States Department of Agriculture for the 

 determination of the species of Salix, to Kenneth K. 

 Mackenzie for the determination of Carex material col- 

 lected in the park region, to Neil Hotchkiss for the 

 determination of the grasses, to Eileen W. Erlanson for 

 the determination of the roses, to Frank \Y. Johnson of 

 Buffalo for a number of additional records of plants 

 collected by him in the park, and to others who 

 have contributed valuable suggestions, information and 

 photographs.
