(2781.) D. Canadensis, Hook.; Macoun, Cat. IV., 204.

Prof. Scribner writes of Nos. 34 & 35 - "Perhaps G. Canadensis; No, 34 = 482 E. Palmer (1887) from Utah; and more exactly a grass I have from the Cascade Mountains, collected by Mr. Frank Tweedy in 1882." No. 34 is from Kamloops; and No. 35 from mountains north of Griffin Lake, B.C. Alt. 6500 feet. 1889. (Macoun.)

(2792.) D. rubescens, Vasey; Macoun, Cat. IV., 207.

Our specimens, so called, are referred to D. Suksdorffii, by Professor Scribner. This species is therefore cancelled.

(2795.) D. Suksdorffii, Scribner; Macoun, Cat. IV., 207.

Rather common on rocky hillsides at Sicamous, B.C. 1889. (Macoun.)

(3205.) D. chalybaea, Fries.?

Of No. 36, collected at Shuswap Lake and Spence's Bridge, B.C., 1889, Prof. Scribner writes: "No. 36b = 357, Scribner. This grass seems to me distinct from G. stricta, Fries. Judging from descriptions it does not appear to differ from G. chalybaea, Fries."
