54 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



la. Alopecurus geniculates fulvus (J. E. Smith) Richter, PI. Eur. 1: 38. 1890. 



Alopecurus fulvus J. E. Smith in Sowerby, Engl. Bot. pi. H67. 1793. 



Alopecurus aristulatus Michx. Fl. Bor. Amer. 1: 43. 1803. 



Alopecurus howellii merrimani Beal, Grasses N. Amer. 2: 278. 1896. 



'Alopecurus howellii merriami Macoun in Jordan, Fur Seals North Pacif. 3: 573. 1899. 



Distribution similar to that of the species. 



Specimens examined: Kodiak, Evans 377a; Fort Selkirk, Tarleton 121; St. 

 George Island, Merriam in 1891; St. Paul Island, Macoun 16636, Palmer; Unga, 

 Piper 4718. 



The specimens collected by Merriam and Macoun cited above represent the form 

 described by Beal as Alopecurus howellii var. merrimani, which differs from typical 

 Alopecurus gcniculatus fulvus only in its low stature and shorter spikes, characters due 

 only to habitat, as both specimens cited above were collected in bare dry soil. 



2. Alopecurus alpinus J. E. Smith in Sowerby, Engl. Bot. pi. 1126. 1793. 



A glabrous, erect perennial 10 to 60 cm. high, with flat leaves and cylindrical or 

 ovoid, densely flowered spike-like panicles 1 to 3 cm. long; spikelets 4 mm. long with 

 obtuse, densely villous glumes, about the length of the lemma, this bearing on the 

 back just below the middle a slender awn that equals or somewhat exceeds it in 

 length. • 



Arctic Alaska and the islands of Bering Sea to Cook Inlet and the upper Yukon, 

 thence eastward to Labrador; also in the arctic regions of Europe and Asia. 



3. Alopecurus stejnegeri Vasey, Proc. U. S. Nat. Mus. 10: 153. 1887. 



A stout perennial 15 to 30 cm. high, the culms decumbent and geniculate below, 

 with inflated sheaths, conspicuous ligule, and ovoid or oblong, densely pubescent, 

 spike-like panicles 2 to 4 cm. long; glumes lanceolate, densely villous, about one-third 

 longer than the lemma, this 4 mm. in length and bearing an awn near the base which 

 equals or slightly exceeds the glumes. 



The type specimens were collected at South Rookery, Bering Islands, and at Kara- 

 belnij on Copper Island, in Russian territory, by L. Stejneger, August 21, 1882, and 

 the species will doubtless be found within the American limits. 



5. PHIPPSIA R. Br. 



Phippsia R. Br. Suppl. App. Parry's Voy. 275. 1824. 



Spikelets 1-flowered, hermaphrodite, very small; glumes minute, unequal, or the 

 first sometimes wanting; lemma thin-membranaceous, somewhat carinate, with the 

 apex irregularly dentate, awnless. A dwarf perennial, with narrow, flat leaves, 

 which are scarcely exceeded by the very slender, few-flowered panicles. 



1. Phippsia algida (Soland.) R. Br. Suppl. App. Parry's Voy. 275. 1824. 



Agrostis algida Soland. in Phipps, Voy. 200. 1774. 



A low, tufted, glabrous grass 2 to 10 cm. high, with narrow, soft leaves and con- 

 tracted simple panicles; spikelets 1 to 1.5 mm. long; glumes minute, unequal, acute, 

 the lemma broad and obtuse or erose-truncate. 



Islands of Bering Sea, arctic North America, and on the highest mountain peaks 

 of Colorado; also in northern Europe and Asia. 



Specimens examined: St. Paul Island, Palmer 459; St. Matthew Island, Coville 

 & Kearney 2106; St. Lawrence Island, Coville & Kearney 1994. 



6. ARCTAGROSTTS Griseb. 



Arctagrostis Griseb. in Ledeb. Fl. Ross. 4: 434. 1853. 



Spikelets i-flowered, hermaphrodite; glumes 2, usually unequal, acute, awnless; 

 lemmas usually a little longer than the glumes, obtuse or subdentate at the apex, 

 imperfectly 5-nerved, awnless. Perennial cespitose grasses, with flat leaves and 

 contracted or open, terminal panicles of rather large spikelets.
