A List of Grasses from Washington Territory. 
By F. Lamson Scribner.

(By the wise liberality of Mr. Villard and his associates, who now 
control the Northern Pacific Railroad system, a very extended and 
complete economic survey of the territory tributary to these enter- 
prises has for the past two years been prosecuted under the able 
direction of Professor Raphael Pumpelly. A year since a Division of 
Forage Plants and Statistics was organized, and Mr. T. S. Brandegee, 
who has for years done excellent botanical service^ was appointed as 
observer and collector with the party operating in the Yakima River 
region and the adjacent parts of the Cascade Mountains in Washing- 
ton Territory. Mr. Frank Tweedy was also with the party as to- 
pographer, and found time to make a fine collection of excellent 
specimens. The grasses obtained by these gentlemen have been 
critically studied by Mr. Scribner, and the result as given below 
shows the excellent outcome of their united labors. — W, M. Canbv.)

' Agrostis alba.Y.A There is no palea manifest, but the general 
characters of the plant point rather to A, alba than to A. data. 
Agrostis temiifolia, Bieb., Trin. Icon., 3. t .65. This appears like 
a slender, narrow^eaved, awnless form of Agrostis exarata, and 
has been so referred (No. 1,127, Kellogg &: Hartford). It seems to 
be a well marked species, however, and so well accords with Trinius's 
figure of A, tenuifoUa that I have little hesitation in referring it to 
that species. As I understand A. exarata, I am 'not prepared to 
unite this species with it, 
Agrostis geminata, Trin., Uniflor. 207 ; Icon. 3. t. 2^. A very 
delicate and pretty alpine species about a foot in height, the hair- 
like, spreading branches of the panicle few-flowered at the ends, 
and the flowering-glume slender awned. 
Agrostis varians^ Trin. 
Agrostis /oliosa, Vasey, ined. Equals Nos. i and 47 o^ Howell's 
Oregon coll. 
Agrostis exarata, Trin. The same form as represented by No. 
619 E. of Hall's Oregon collection. There is also a larger, more 
densely flowered and awned form, with strongly scabrous leaves.
