22 Report of the State Botanist. 



Scirpus Peckii Britton. 

 Lake Pleasant, Hamilton County. August. First collected 

 in this locality in 1875. It Avas again collected in 1891, 

 but in a new station. It Avas reported last year under 

 the name Scirpus polyphyllus var. macrostachys. Professor 

 Britton has recentl}" published it as a distinct species, and as such 

 it is now reported. It certainly is quite distinct from our ordinary 

 forms of S. polyp)hyll%Ls. Specimens sometimes occur in which a 

 cluster of spikelets is borne on a long pedicel issuing from the 

 axil of the uppermost leaf.

 thick. 



Woods. Shokan. September. 



This is apparently related to such species as T. psammopodum 

 and T. impolitum, but distinct from them in color and in the 

 character of the lamellne.
