 Morong ; Tompkins Co., N. Y., Dudley ; Jefferson Co., N. Y., 

 Crazve ; and Keweenaw Co., Michigan, FarzvelL Before fully 

 mature, the spikes are not stellate, and specimens may readily be 

 mistaken for C. canescens^ vdiV, polystachya, Boott, to which plant 

 Morong's specimens were referred in my Synopsis. (See adden- 

 dum.)
