near Niagara River very little has been done in the Ontario District. 

 In that part of the Erie District which lies west of Niagara River 

 many localities remain to be investigated. But it is very safe to say 

 that all our characteristic flowering plants and all our more abundant 

 cryptogams are named in the Catalogue. The species hereafter to 

 be detected within our limits will probably be found in scanty 

 numbers and inhabiting very narrow bounds. 



The naturalized plants of Buffalo are a large and increasing num- 

 ber. In accordance with usage their names appear in the Catalogue 

 in small capitals. Several of them are of recent introduction: — 

 a few as garden escapes, but the larger number through the agency 

 of the southern and western railways. It is doubtful whether 

 all these strangers will long remain; but it may be said that, in case 

 they should disappear, they are likely to be introduced again in 

 the same way. But some of them manifest a wonderful capacity 

 of persistence and increase; — notably, Artemisia biennis (with us 

 uniformly an annual), which, twenty years ago" was a rare plant, 

 but is now met with in superabundance. 



Early in the history of the Society, the investigation of our 

 Lichens was generously undertaken by Miss Mary L. Wilson, then 

 of our city, now of Haverhill, Mass. The success which attended 

 her efforts in this difficult and neglected field, is demonstrated by the 

 very valuable collection of plants of that order, constituting a part 

 of the Herbarium. Miss Wilson has now enhanced the value of 

 her labors by preparing with her own hand the list of the Lichens 

 of Buffalo which makes a part of the Catalogue. 



It is confessed, with much regret, that the investigation of the 

 Algae of Buffalo has been greatly neglected. The list of them 

 which appears in the Catalogue is from the very competent hands of 

 Prof. David S. Kellicott, of the State Normal School in this city. 

 But, unfortunately, Prof. K.ELLICOTT has not been able to give to 

 their study more than a small portion of his time, and that only 

 during the last few seasons. It may, however, be confidently expected 

 that, at no distant time, a revised list of the Algae of Buffalo will 

 be issued by the Society, with such extensions and corrections as, 

 upon further research and examination, may appear necessary. 



Grateful acknowledgments are made to Mr. Charles H. Peck, 

 of Albany, N. Y., the State Botanist, for his kindness in supervising
