Var. paleata, Vasey, (MS.) N. Var.

Abundant in meadows at Cedar Hill, near Victoria, Vancouver Island, 1887. (Macoun.) This is a fine grass and seems to be valuable both as a pasture and meadow grass. A variety of A. canina was gathered at Sitka a few years since by Mr. Meehan, which may be this form.

(2767.) A. oreophila, Trin.

On an exposed point of rocks, a few hundred yards east of South West Point Lighthouse, Anticosti, August 17, 1883. The specimens are doubtfully referred here by Dr. Vasey, our highest authority on grasses in Ameriea. Dr. Gray in his Manual, page 611, seems to refer this to A. scabra, but it cannot be that species as this is perennial (Macoun.)
