Zonal distribution: Humid Transition to Hudsonian. 



A variable species not much different from the European spadiceum. Our common 

 form has lax panicles and pale perianth segments and capsule, and is nearly the same 

 as Luzula parvijlora sparsiflora Lange. The form with dark capsules, Luzula pannjlora 

 melanocarpa (Desv.) Gray, does not seem to occur in our limits. 



3. Juncoides piperi Coville, sp. nov. 



Densely tufted, from short horizontal usually matted rootstocks; stems erect, 10 to 35 

 cm. high; leaves mostly basal, firm in texture, pale green and dull, erect or nearly so, 

 linear-lanceolate, attenuate, 2 to 4 mm. broad, 15 to 17-nerved, about one-fourth as long 

 as the stem, smooth and glabrous except for a few long hairs on the .sheaths and margins, 

 inclined to become revolute; cauline leaves two or rarely three; panicle 5 to 8 cm. long, 

 dark brown, nodding; lowest bract foliaceous, usually 8 to 15 mm. long; bractlets brown, 

 paler and hyaline toward the apex, lacerate; flowers solitary on the branches or sometimes 

 in clusters of two or three; perianth segments dark brown, nearly equal, ovate, acuminate, 

 about 1.5 mm. long; stamens half to two-thirds the length of the perianth, the anthers 

 nearly equaling the filaments; style about .2 to .3 mm., stigmas 2 to 3 mm. in length; 

 capsule dark brown, exceeding the perianth, its valves broadly ovate, broadly acute, indis- 

 tinctly or not at all apiculate; seeds of a light brown to buff or amber color, about 1.2 mm. 

 in length, lanceolate-oblong in outline, narrowed to each end, distinctly keeled on the inner 

 side, the cellular reticulations faint. 



Type specimen United States National Herbarium no. 352425, collected in September, 

 1897, by A. D. E. Elmer (no. 678) in the Cascade Mountains of Okanogan County, Wash- 

 ington, on the north fork of Bridge Creek, growing '"on dry sand-gravelly moraines just 

 below the glaciers at 6,000 feet altitude." 



This species difTers from Juncoides parviflorujn in its more densely tufted habit, smaller 

 size, and more lacerate bractlets, thicker, never shining leaves, the lack of a distinct apicu- 

 lation on the capsule valves, and the light-colored pointed seeds. In parvifioruin the seeds 

 are dark brown, narrowly oblong in outline, and blunt at the ends. Our species bears a 

 superficial resemblance to the European spadiceum, but is readily distinguishable by its
