 Old logs in marshes and exsiccated places ; infrequent. July- 



Aug. 



Eagle Hill. Michigan Hollow and other marshes. 



1210. A. vulgaris, With. Red Top. (C.) 

 Fields ; common. The typical form — slender and with few 



branches to the panicle, occurs sparingly in pastures east of Mc- 

 Lean, in Danby, etc. The cultivated Red Top is usually much more 

 robust. 



121 1. A. vulgaris, With., var. alba, Vase)', (A. alba,) L. (H. and C.)

 Shaded wet ravines and deep swamps ; scarce. July, Aug. 



Fall Cr., in the Triphammer ravine. Near Beaver Creek. Near 

 Locke Pond. A peculiarly delicate form with smaller flowers than 

 the typical one occurs in Michigan Hollow Swamp. 

 437. Deyeuxia, Clair. 



1 214. D. Canadensis, Beauv. {Calamagrostis Canadensis, Beauv.) 

 Beue-joint. (H. and C.) 



Open marshes ; common. June 20-July 10. 



Inlet Marshes. In Dryden and Danby. Abundant on the Cayu- 

 ga Marshes. Occasional in ravines. The awn arises^ from much be- 

 low the middle of the palet in specimens from Farley's Point.

1 215. D. Ported, Vasey, (C Porteri, Gr.) 



Local and very sparingly on Thacher's Pinnacle near W. Danby, 

 in woods of Rock Oak, Hickory, with Vacciniums, Azaleas, etc., 

 1881. These specimens are less robust than the type ; but after a 

 careful examination of plants, from our locality and from Pennsyl- 

 vania, and an interesting correspondence with Prof'r Porter, the 

 discoverer of the species, and with Dr. Vasey, to both of whom speci- 

 mens were submitted, there remains but little doubt that D. Porteri 

 is established as a N. Y. plant. It has hitherto been found only in 

 a limited section of Pennsylvania, but Prof. Porter, who has col- 

 lected more of it than any one else, agrees that our specimens should 

 be referred to his species. 



438. Deschampsia, Beauv. 



1216. D. flexuosa, Vase}-. {Airaflextcosa, L.) Hair Grass. 



(H. and C.) 

 Dry or rocky slopes ; scarce. June 20-July 20.
