(3206.) M. spectabilis, Scribner. 



In a mountain valley, north of the Thompson Elver, between 

 Spenco's Bridge and Lytton. 1889. {J. M. Macoun.) 



723. POA. 



(2859.) P. Eatoni, Watson?; Macoun, Cat. IV., 225. 



On the mountains at Spence's Bridge, B.C., 3889. This is the same 

 species referred to P. Calif ornica in Part IV. There is still doubt 

 where this should go. (Macoun.) 



(2863.) P. laxa, H«nke ; Macoun, Cat. IV., 225. 



Quite common on the mountains north of Griffin Lake, Gold Range, 

 B.C. Alt. 6500 feet. 1889. (Macoun.) 



(2868.) P. Nevadensis, Vasey; Macoun, Cat. IV., 226. 



On the mountain side at Tale, at Spence's Bridge, and at Kamloops, 

 B.C. 1889. (Macoun.) 



(28^0.) P. purpurascens, Vasey; Macoun, Oat. IV., 226. 



Summit of the mountains north of Griffin Lake, B.C. Alt. 6500 feet. 

 1889. (Macoun.) 



(2813.) P. stenantha, Macoun, Cat. IV., 227. 



Prof. Scribner writes me that my specimens of this species are his 

 Poa Vaseyana, var. angustifolia, Tweedy, 1885. It is not P. stenantha, 

 B. Brown. 



(2873.) P. subaristata, Macoun, Cat. IV., 227. 



Of this Prof Scribner writes — " I have in my herbarium no P. 

 subaristata. Your grass is the same as 631 Tweedy (1885 Yellowstone 

 Park Coll.) which I referred doubtfully to Poa andina, Nutt. I col- 

 lected in Montana exactly the same form. ISTuttall never published 

 his Poa andina. I have never seen and do not know Poa andina, 

 Trin. Your grass belongs to a section of the genus not well under- 

 stood, and one represented by many forms in the Eooky Mountains. 

 The grass you sent me ticketed Poa andina, Nutt., var purpurea, 

 Vasey, is like the type of Poa andina, Nutt., in Nuttall's writing in 

 herb. Phila. Acad. Kat. Sciences." 



We have still a few Poas undetei-mined, and hope to have them 

 settled during the coming year.
