ones; a^iex entire or shortly 2-toothe(l ; awns dmrhr, 0-9 mm. long. Joints of the 

 racliilla 2-3 mm. long, pubescent; i)alea nearly or- quite equaling its glume, 

 ciliate on the keels and scantily pubescent l)et\veen them. 



Type: Hooker 1. c. refers several collections made by Richardson, Douglas, and 

 Scouler to this species. Through the kindness of the director of the Kew (xar- 

 dens we have received a spikelet from the specimens collected by Dr. Scouler on 

 the Columbia which proves to be the same as the synonyms given. 



General distril)ution: California north to Vancouver Island, east to Montana and the 

 Blue IVbiuntains of Oregon. The typical form seems to be most frequent in the 

 Blue Mountains.

This plant has most frequently been referred to B. ciliatna heretofore, but is easily 

 separated from that species by its smaller panicle, longer awn, and long ligule, 

 and also by the distribution of the pubescence on the flowering glume. It is 

 quite variable in some respects and seems to pass through its various forms into 

 B. Urripes. 



2Sa. BROMUS VULGARIS EXIMIUS n. var. Bromus dliatus glaberrimus 

 Suksdorf in herb. Not B. glaberrimus Koch, Linnfea, 21: 420. 1848. 



A more erect and robust plant than the type, leaves broader, in the type 1 cm. broad, 

 leaves, sheaths, and culms glabrous as is al.«o the flowering glume except on the 

 margin and midnerve near the base where it is scantily pubescent. 



Type No. 1791, collected by C. L. Shear on moist, open mountain side 4 miles above 

 Wallowa Lake, Oregon. 



General distribution : Oregon and Washington. 



Specimens examined. — Oregon : near Wallowa Lake (C. L. Shear 1787, 1799). Wash- 

 ington : Skamania Co. (W. N. Suksdorf 2335). This number was the type of 

 Suksdorf's variety cited above. Yakima region (F. Tweedy, July, 1882). 



23/i. BROMUS VULGARIS ROBUSTUS n. var. 



A tall leafy form sometimes reaching 15-18 dm. high; leaves and sheaths sparsely 

 pilose-pubescent; the jianicle larger than in the species and having the flowering 

 glumes pubescent on the margin and keel at the base, as in B. vulgari,s eximitis, 

 from which it differs chiefly in the pilose-pubescent leaves and sheaths and 

 rather larger panicle. 



Type No. 1710, collected by Scribner and Shear in moist thickets near the seashore, 

 Seaside, Oregon. 



General distribution: Oregon to Vancouver Island along the coast; also from Idaho. 



Specimens examined. — Orcg(nt : Seaside (Scribner & Shear 1707, 1710); ]\IcMinnville

 Washington: Base of Mount Adams (W. N. Suksdorf 176), near Montesano 

 (A. A. & E. G. Heller 3999). Vancouver Island : (J. Macoun 176) not typical.
