Plant records from southwestern New York — 11' 



Irving William Knobloch 



During the course of the past year, I have had an oppor- 

 tunity to further study the plants of the southwestern part of 

 the state, particularly those of Cattaraugus and Chautauqua 

 counties. Aside from the "Flora of the Allegany State Park 

 Region" by Homer D. House and William P. Alexander, little 

 has been published on the local plants. My first study of the 

 local flora was published in Torreya 36, i: 1-2, February, 

 1936. Species not previously recorded for this area: 



Galinsoga parviflora Cav. 



This adventive member of the compositae was noticed in 

 waste places in the city of Salamanca, N. Y. during 

 November, 1936. 



Aster Lowrieaniis Porter 



This beautiful aster was seen rather frequently in open 

 woods in the Allegany State Park, particularly in the 

 part adjacent to the C.C.C. camp No. 51. Collected on 

 Sept. 24, 1936. 



Aster caesia L. 



This species was found on the same day in the same 

 places as the previously mentioned aster. 



Potamogeton panormitanus Biv. 



I located this species in the Allegheny river south of 

 Red House, N. Y. on Oct. 7, 1936. Dr. Fernald first 

 recorded this species as distinct from P. pusillus in this 

 country. (Fernald, M. L. The Linear-leaved Species of 

 Potamogeton. Memoir American Academy of Science 17: 

 Pt. 1, 183 pgs., 1932) P. pusillus was collected by Dr. 

 Gordon in Stillson's pond near E. Randolph, N. Y. in 

 1932. 



New stations for previously recorded or collected species: 

 Potamogeton foliosus Raf . 



Located in 1934 in the Allegheny river near Quaker 

 Bridge, N. Y. by Dr. Robert Gordon. I found this species 

 in a stagnant pool at the state fish hatchery near E. 

 Randolph, N. Y. on July 20, 1936. 



Part I was printed in Torreya, Vol. 36, No. 1, Jan. -Feb., 1936.
