Some recent observations on and additions 

 to the flora of Western New York 



Irving William Knobloch 



Since the publication of Mr. Charles Zenkert's "Flora of the 

 Niagara Frontier Region," a Buffalo Society of Natural Sci- 

 ence Bulletin, the exact status of the local ilora has been much 

 clarified. Local enthusiasts can now proceed with certainty 

 when calling attention to new adventives or otherwise rare spe- 

 cies in our midst. 



Using this fine volume as a guide, supplemented by the 

 "Flora of the Allegany State Park Region" by Homer D. House 

 and William P. Alexander, which covers that region of Cat- 

 taraugus County, south of Salamanca, N. Y., a fairly complete 

 list of Western New York plants is available. 



After a perusal of the two above-mentioned volumes, I sub- 

 mit the following records which should be interesting to stu- 

 dents of local conditions. 



Erie County: — 



Equisetum scirpoides Michx., the Sedge-like Horsetail, has not 

 been located in this county heretofore. It was located on May 

 13, 1934 by Mr. Gerhard Blodorn at Lawton's Corners, N. Y. 



Thuya occidentalis L., the Arbor Vitae, is not mentioned in 

 Mr. Zenkert's flora as occurring in Erie County. It was quite a 

 surprise to note a good-sized cedar swamp about fifteen miles 

 from Buffalo, near the town of Alden. It is an altogether beauti- 

 ful and interesting locality since Benzoin aestivale, Drosera 

 rotundijolia, Rhamnus alnifolia, Cystopteris bulbifera, Aralia 

 racemosa, Spiranthes cernua and Conioselinum chinense are 

 all more or less closely associated with the restful green of the 

 arbor vitae. 



Allegany State Park:- — 



In this huge sixty-five thousand acre tract, one of two un- 

 glaciated areas in New York state, many plants are missing 

 which are found a few miles north, in glaciated soil. However, 

 there is quite an interesting flora despite the lack of boreal ele- 

 ments.
