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 iV. odorota var. minor, Sims. He says : — " The 

 plant may at once be distinguished from the eastern N. odorota var.

 with narrow, acutish lobes, and the flowers still smaller with 7^8 

 rayed stigma." Misinaibi Eiver, Northern Ontario, ISTQ. (i?. Bell.)

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. paiustre in our pos- 

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