to 10 mm. wide, pubescent on both surfaces: panicle long- 

 exserted, 1 to 2 or rarely even 3 dm. long, drooping but usually 

 not heavy, the rachis branches and pedicels puberulent through- 

 out; branches mostly in pairs below, long, slender, spreading or 

 reflexed, bearing 1 to 3 or sometimes several spikelets near the 

 end, remote, the lowest 2 J to 8 cm. apart: spikelets 28 to 40 

 mm. long, narrow, sub-terte, 6- to 11-flowered; empty glumes 

 unequal, acute, 3-nerved, pubescent, the lower 6 mm. the upper 

 8 mm. long; flowering glume densely pubescent except at the 

 extreme apex with appressed hairs, obtuse, terminating in a 

 short awn 4 to 5 mm. long. 



Type locality : " Wooded slopes and benches of the south side 

 of the San Jacinto Mts., at 5300 ft. alt., June, 1901." H. 

 M. Hall, no. 2228. Type specimen in the Herbarium of the 

 University of California. 



Range: Canons and wooded slopes of the San Jacinto and 

 San Bernardino Mts.; San Bernardino Mts., Waterman's Canon, 

 May 29, 1888 (S. B. Parish), and mouth of Snow CaiJon, 5500 

 ft. alt., June 20, 1901 (S. B. Parish, no. 5038). 



This is undoubtedly the plant referred to by Shear, under his 

 original description of B. Porteri Janafipes, as not being typical 

 of that variety and as approaching B. Icevipes; he cites S. B. 

 Parish nos. 253 and 2533a, and S. B. and W. F. Parish no. 

 1535, from the San Bernardino Mts. The Calif ornian plant 

 differs from B. Porteri lanatipes of the Rocky Mt. region 

 in its less densely pubescent sheaths (described as "densely 

 soft-downy or woolly,") and the greater pubescence of the 

 stems, leaf-blades, pedicels, and empty glumes. From B. vul- 

 garis, which ranges from middle California north to British 

 Columbia, it differs in its 3-nerved lower empty glume and more 

 obtuse flowering glume, the longer and more abundant pubesence 

 on both, and the shorter awn. It appears to approach more 

 nearly to B. hpvipes, which ranges from middle California to 

 Oregon, but it is at once distinguishable on account of its more 

 abundant pubescence throughout and its smaller and fewer- 

 nerved empty glumes. It appears to be related also to B. 

 Richardson i of the Rockj- Mountain region, l)ut dift'crs in the 

 much greater pubescence of all of its parts. How long these
