(2796.) D. borealis.
An imperfectly characterized species, having the general appearance of D. Iapponica, has been named (by Dr. Vasey) D. Vancouverensis, in Bulletin Torrey Botanical Club, Vol. XY., 48. It is indicated as a "small species, 10 or 12 inches high, with spicate panicle 1 1/2 to 2 inches long, approaching D. strigosa, Kunth." It grows plentifully in water at Fort George, James Bay. Collected July 1887. (J. M. Macoun.) With Dr. Vasey's permission I have changed the name to the above, which is more in accordance with the locality where found.
(2797.) D. Columbiana.
This species is related to D. Aleutica, but the specimens are very poor and difficult to characterize. Collected at Ta-gish Lake, Lewes River, N.W.T., Sept. 1887. (Dawson.)
