Dr. Britton of Columbia College, New York, after a careful examina- 

 tion of all available specimens has satisfied himself that this species 

 is quite distinct from N. odorota var. minor, Sims. He says : " The

Our specimens placed here agree exactly with SuksdorfF s plant col- 

 lected May 4th, 1885, and distributed with the above name. The long 

 pods, over half an inch long, with stiff branching stem and deep fusi- 

 form root distinguish it from all other forms of N. palustre in our pos- 

 session. Our specimens are from Port Hancy, and Agassiz in the lower
