PIPER NORTH AMERICAN SPECIES OF FESTUCA. 27 



15c. Festuca ovina supina (Schur) Hack. 



Festuca supina Schur, Enum. PL Transs. 784. 1866. " Auf Felsen und Gerolle der 

 Hochalpen: Fogaraser-Arpaser-Kerzesorer-Rodnaer Alpen, Glimmerschiefer; Kron-

Festuca oiina supina Hack. Bot. Centralb. 8: 405. 1881. 



This subspecies ranges from Greenland southward to the White Mountains, and 

 in the west occurs from British Columbia and Alberta south in the Cascades and 

 Sierras to California, and in the Rockies to Arizona. Apparently it does not occur 

 in Alaska. 



This plant has been generally confused by American botanists with F. orlna 

 brachypJiylla, from which it is often separable with difficulty. 



15d. Festuca ovina duriuscula (L. ) Koch. 



Festuca duriuscula L. Sp. PI. 1: 74. 1753. "Habitat in Europae pratis siccis." j_ 

 Festuca ovina duriuscula Koch, Syn. 812. 1857. 



Judging from herbarium material this subspecies is but sparingly introduced in 

 America. Most specimens so named are F. rubra. 



15e. Festuca ovina capillata (Lam.) Hack. 



Festuca capillata lu2im.. Fl. Fr. 3: 597. 1778. Type locality, France. 

 Festuca tenuifolia Sibth. Fl. Oxon. 44. 1794. Type locality, Oxford, England. 

 Festuca ovina capillata Hack. Bot. Centralb. 8: 405. 1881. 



This very distinct-appearing subspecies is introduced in many places in the eastern 

 United States. 



15f. Festuca ovina pseudovina Hack. 



Festuca ovina pseudovina Hack. Bot. Centralb. 8 : 405. 1881. Hackel's name is 

 proposed for the Austrian grass mistaken for true F. ovina L. by Host, Gram. Austr. 

 2: pi. 86. 



This subspecies occurs native in North America in the Rocky Mountains of Wyom- 

 ing, Colorado, and Utah. Specimens from Clarke, Indiana, collected by Umbach, 

 are probably introduced. 



15g. Festuca ovina brachyphylla (Schultes). 



Festuca hrevifolia R. Br. App. Parry's Voy. Suppl. 289. 1824. Type from Melville 

 Island. A duplicate in the Gray Herbarium. 



Festuca brachyphylla Schultes, Mant. 3 : 646. 1827. Proposes new name on account 

 of the older F. hrevifolia Muhl. 1817. 



Festuca ovina hrevifolia Hack. Bot. Centralb. 8: 406. 1881. 



This subspecies ranges in North America from the Arctic regions southward to 

 Labrador, and in the Rocky Mountains to Arizona, and recurs in the Sierras of Cali- 

 fornia; apparently absent in the Cascades, but present in the Blue Mountains of 

 Oregon. 



15h. Festuca ovina calligera nom. no v. 



Festuca amethystina asperrima Hack.; Beal, Grasses N. Am. 2: 601. 1896, not F. 

 asperrima Link, Enum. 2: 270. 1822. Type in the National Herbarium, collected in 

 Aiizona by Rusby (no. 901). 



Plants densely tufted, pale green, 15 to 50 cm. high; stems covered at base by the 

 brown scarious persistent sheaths; leaf-blades filiform, longitudinally sulcate,.'cabrous, 

 5 to 15 cm. long, each bearing at its junction with the sheath a small callus on each 

 side; lemma awned; palea bidentate.
