22 Report of the State Botanist. 



Scirpus Peckii Britton. 

 Lake Pleasant, Hamilton County. August. First collected 

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

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

 the name Scirpus polyphyllus var. macrostachys. Professor 

 Britton has recently published it as a distinct species, and as such 

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

 forms of S. polyphyllus. Specimens sometimes occur in which a 

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

 axil of the uppermost leaf.

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

 character of the lamellae.
