Carex formosa Dew. 

 This rare species was found in Seneca park, Rochester, on June i. 

 It was then in good condition for collecting. 



■ Carex setifolia (Dew.) Britton 

 Limestone rocks, cliffs and precipices are generally given as the 

 habitat of this pretty little sedge. But it is not limited to such 

 places. Fine specimens of it were found in July growing in wet, 

 mucky soil in woods about Bergen swamp. In more open wet 

 places near it the rare Carex crawei Dew. was found, 



Cercospora circumscissa Sacc. 

 This fimgus was plentiful in the region about Lake Pleasant the 

 past season. It attacks the living leaves of the chokecherry and 

 the wild blackcherry. It kills the leaf tissues in small circular spots, 

 and the dead tissues soon separate from the living and fall, leaving 

 clean-cut circular perforations in the leaf. i.^ ^ 



Cypripedium reginae Walt. 

 A form of this showy species occurs in Bonaparte swamp in 

 which the whole flower is white, 



Eleocharis palustris vigens Bail. 

 This is a tall stout variety growing in shallow water. It was 

 found growing in Oneida lake at Lakeport and specimens were 

 collected. Variety glaucescens was found growing in low wet 

 places at South Bay and in Bonaparte swamp. Judging from the 

 external appearance alone it would be difificult to believe that 

 these two plants are varieties of the same species. 



Eriophorum alpinum L. 



The alpine cotton grass is now plentiful in one place in Bona- 

 parte swamp though it was not seen in my exploration of the 

 swamp in 1899. It is also abtindant in an old meadow near Elm 

 lake in Hamilton county. 



Fragaria americana (Porter) Britton 



This strawberry is abundant in groves and the bordsrs of woods 



at Lake Bonaparte. The flowers are scarcely more than 3 lines 



broad. 



Gratiola aurea Muhl. 



Fine specimens with slender weak stems a foot or more long 

 were found growing in the marshy borders of a lake near Smith- 

 town, Suffolk CO.
