REPORT OF THE DIRECTOR 1898 rl5 



This disagreement affects about 600 names of New York species of 

 flowering plants and ferns. A list of the names of these species is 

 given, those found in the Manual standing in one column and the 

 corresponding names in the Illustrated flora ^i2j\.(\mg o^^o^itQ them 

 in another. 



A record is made of species found in the state but not before 

 officially reported as belonging to its flora. This record gives the 

 name of the locality where the plant was found, the month in which 

 it was found and any other matter of interest observed concerning 

 it. The number of species added to our flora is 57. In a similar 

 way a record is made of species previously reported but concerning 

 which something new has been learned or some observation of in- 

 terest has been made. This part of the report includes remarks on 

 39 species. 



A brief account of some of the physical features of the open sum- 

 mit of Mt Marcy, the highest mountain in the state, reference to 

 its climatic and meteoric conditions and their influence on its 

 vegetation and a list of the names of plants found growing there are 

 given. These number 206 species. To this list, remarks are added 

 concerning some of the more interesting and notable species. 



The final chapter contains descriptions of 12 edible species of 

 mushrooms on the plan of those described in previous reports. A 

 brief scientific diagnosis of the species is followed by a simple de- 

 scription in plain language, as devoid of technical terms as possible. 

 These species are illustrated by colored drawings of natural size on 

 five quarto plates. An index to the report is added.
