Jong; the upper 5-nerved, broader, 9-11 mm. long; flowering glume obtuse, 7-nerved, 13-15 mm. long, densely ciHate-pubes- cent on the margin nearly to the apex and also on the bacJc at the base; apex hyaline, emarginate,usually brown- ish yellow; awn straight, 3-4 or rarely 5 mm. long; palea about 2 n:im. shorter than its glume. Type No. 178, collected by W. N. Suksdorf on the Colum- bia River, West Klickitat Co., Washington. General distribution: Mostly in the Coast Range and Cascade Mountains, Cali- fornia, north to Washing- ton. Specimens examined.âCalifor- nia: Hood's Peak (Bioletti 112); Black Mt. (C. Rut- ter 1); San Jose (Miss Bush); Borax Lake (J. Torrey 574âa poor speci- men, somewhat doul)tful); Pitt River, Shasta Co. (H. E. Brown 279); Head of Russian R i ^⢠e r (J . W . Blankinship 41); Agricul- tural Station, Amador Co. (Geo. Hansen 610); no locality (G. R. Vasey). Oregon: Grant's Pass (T. Howell 250). This species is closely related to B. r(dgaris,B. orcutiianns and B. richardsonipallidus. From the first it is distinguished by its smooth leaves and sheaths and much stouter haliit, as well as broader spikelets and denser pubescence of the flowering glume. From the second it differs in the larger drooping panicle and different distribution of pubescence on the flowering glume. It appears close
