and correcting our lists of Musci, Hepaticae and Fungi: — originally 

 prepared by Judge Clinton, by whom all the species were detected, 

 except as otherwise stated. 



For the accompanying map we are indebted to Mr. Julius 

 Pohlman, Custodian of the Society, and to Mr. Henry Chandler, 

 of this city, who has generously assisted in the engraving of it. It 

 is hoped that it will prove of use, ncj. only at the present time, but 

 in the future, as a guide to the localities in which some of the rarer 

 and more interesting members of our Flora were detected. The 

 altitudes, given upon the map, of various places named in the Cata- 

 logue, have been obtained in all instances from sources which, it was 

 thought, could be relied upon. In the main, it is to be presumed 

 that they are nearly, if not quite, accurate. 



It will be seen that the names of a few species, which appear in the 

 Catalogue, are not accompanied by numbers. In such instances the 

 plants are mentioned either because they are known to have formerly 

 existed in this vicinity, although they have now disappeared, or 

 because there is evidence, more or less satisfactory, for believing 

 that they actually belong to our Flora, and will yet be detected 

 here. In any event, however, as they are not numbered, their 

 inclusion in the Catalogue will not lead to any misapprehension. 



Whenever any plant is named and its locality is not given it 

 may be understood that the plant is one of general diffusion 

 through our territory. When localities are given, they are men- 

 tioned in the order of their distance from Buffalo: — the nearest first. 

 In all such cases it may be understood that the compiler has re- 

 garded them as among our rarities. All phaenogamous plants and 

 their stations are named upon -the authority of his personal observa- 

 tion, except as otherwise stated. From this, however, it is not to be 

 inferred that he claims to have been the discoverer of the species in 

 the localities named. The fact is often to the contrary. 



A word may be of use in explanation of the nomenclature 

 adopted in the Catalogue. Asa rule, the names of species are those 

 employed by Watson, in his " Bibliographical Index to North 

 American Botany," so far as that valuable work has issued from the 

 press. But where such names differ from those given by Gray, 

 in the fifth edition of his Manual, the latter will be found in paren- 

 theses. In a very few instances the compiler has ventured to differ
