 An extremely variable species throughout its range. The unsatisfactory condition 

 of the European forms makes it impossible at present to clearly define the 

 species as represented in North America. Extreme forms approach C. strigosa 

 (Wahlcnb.) Hartm. in their narrow, sharp-acuminate, scabrous empty glumes, 

 but are distinguished by their strongly involute leaves and smaller spikelets. 

 On the other hand, specimens from Long Point, Newfoundland, collected by 

 Waghorne, somewhat resemble C. Japponica (Wahleub.) Hartm. in their lanceo- 

 late, rather open panicles, thin and nearlj-^ glabrous empty glumes, and curved, 

 almost geniculate awn, but differ markedly in their small size, closely involute 

 leaves, small spikelets, and narrow, empty glumes. Other specimens from Hol- 

 toii and Independent, Newfoundland, ajjproach forms of C hyperborca, diii'ering 

 chiefly in their softer texture and less scabrous glumes.

Small (2 to 3 dm. high); longest leaf-blades not exceeding 1 dm.; panicle small, 3 

 to 5 cm. long, 5 to 10 mm. wide, spikelike, usually very dense, dark purple or 

 chestnut brown; spikelets about 3 mm. long; empty glumes ovate, acute; 

 flowering glume nearly equaling tlie empty ones.

Type specimen collected in Lapland. 



Specimens examined. — Labrador: Attilconak Branch, Hamilton River (Low 6080, 

 6081, G. S. C), 1894. Northeast Territory: Fort George, James Bay (J. M^. 

 Macoun 125, 17414 H. G. S. C), 1887 (type of Deyeuxia rancouverensis Vasey and 

 of D. borealis Macoun). 



This variety is related to C. holmii Lange,' which, however, is even a smaller plant 

 (mostly about 1 dm. high), with ascending culms, leaves crowded at the basc'ot 

 the culm with short comi>aratively widespreading blades, longer spikelets anil 

 more acuminate empty glumes. 



CALAMAGROSTIS NEGLECTA CANDIDULA Kearney, var. n. 



Whole plant pale and glaucous; culms 3 to 4 dm. high, ratlier liard and rigid, com- 

 paratively stout, sometimes strongly arcuate below ; lcaf-I)lades somewhat rigid; 

 panicle 6 to 10 cm. long, 1 to 1.5 cm. wide, oblong-lanceolate, densely many- 

 flowered, whitish, tinged with pale purple; spikelets about 4 mm. long; empty 

 glumes rather tirm in texture; flowering glume considerably shorter than the 



'Lange: Holm Novaia-Zemlias Vegetation 20, t. 1, p. 2 (1887). A form of this 

 species has been collected on Wrangel Island, Siberia, and many extend to some of 

 the Alaskan islands.
