the larger 6-10 cm. long and naked at the base : spikelets 

 numerous, about 4 mm. long, on hispidulous pedicels 1.5 

 mm. long or less ; empty scales acute, the first scale i-nerved, 

 about two-thirds as long as the 3-nerved second which is usu- 

 ally about four-fifths as long as the palet ; flowering scale 

 about 3.5 mm. long, 5-nerved, the midnerve hispidulous, the 

 two lateral nerves on each side very obscure and sometimes 

 hardly discernible, acute, strongly hispidulous, in side view 

 oblong and about 0.8 mm. wide ; palet faintly 2-nerved, 

 strongly hispidulous, from a little shorter than the scale to 

 equalling it; stamens 3, oblong-linear, about 2 mm. long; 

 stigmas 2, plumose. 



Type collected by R. S. Williams in wet springy places on 

 mountain sides, Dawson, July 14, 1899. Also collected by 

 F. Funston along the Yukon River, in August, 1893, no. 159, 

 and distributed as A. arnndinacea Trin. It is quite distinct 

 from that species, being taller and having larger and very 

 rough leaves, and lacking the prominent pointed bracts at 

 the base of the culm which gradually pass into leaves, as in- 

 dicated by Trinius in his Spec. Gram. Icon. & Descrip._^>/.

 versity from Kotzebue's Sound, the type locality of the Vilfa 

 arundinacea Trin., exactly matching this figure. 



Arctagrostis poaeoides Nash, sp. nov. 



A somewhat tufted perennial, with a branching running 

 rootstock. Culms 6-8 dm. tali, erect, bracted at the base, 

 the bracts gradually passing into leaves : leaves about 4 ; 

 sheaths striate, shorter than the internodes, very rough ; 

 ligule scarious, 4-5 mm. long, decurrent on the sheath ; 

 blades erect, stiff, exceedingly rough on both surfaces, long- 

 acuminate, 1.5-2.5 dm. long, 5-6 mm. wide: panicle about 

 1.5 dm. long, contracted, its axis almost smooth, the fas- 

 ciculate erect hispidulous branches varying in length, the 

 larger 3-4 cm. long and naked below : spikelets numerous, 

 2.5-3 mm. long, on somewhat hispidulous pedicels usually 

 less than 1 mm. long; empty scales acute, the first scale 

 i-nerved, about two-thirds as long as the 3-nerved second 

 which is usually about four-fifths as long as the palet ; flow- 

 ering scale usually a little less than 3 mm. long, strongly 

 hispidulous, 5-nerved, the midnerve hispidulous, the two
