4-6 cm. long, its branches ascending, the larger ones 2-2.5 

 cm. long, spikelet-bearing above the middle : spikelets longer 

 than their pedicels, in 2's— 4's on the larger branches, varie- 

 gated with yellowish brown and purple, 3— 4-flowered, 5-6 

 mm. long ; empty scales acuminate, hispidulous on the keel 

 above the middle, the first scale i-nerved, the second 3- 

 nerved at the base, the lateral nerves vanishing below the 

 apex, the first scale about three fourths as long as the second 

 which is a little shorter than its adjacent flowering scale ; 

 flowering scale acute, hispidulous on the midnerve above the 

 middle, cobwebby at the base, the lower ones about 4.5 mm. 

 long, 5-nerved, the midnerve and lateral nerves prominent, 

 densely pubescent below the middle with silky hairs, the in- 

 termediate nerves rather faint, sometimes sparingly pubes-

 Aug. 26, 1899. Related to P. arctica R. Br., but distin-

 branches ascending or nearly erect, the larger ones 8-1 1 

 cm. long, naked toward the base : spikelets longer than their 

 pedicels, 5-6 mm. long, 4-6-flowered ; empty scales brown- 

 ish, scarious margined, irregularly toothed at the rounded or 

 obtuse apex, much shorter than their adjacent flowering 

 scales, the first scale i-nerved, shorter than the second which 

 is 3-nerved at the base ; flowering scales usually purple, with a 

 broad hyaline margin above the middle, strongly but minutely 

 hispidulous, oval when spread out, prominently 7-nerved,
