1. Equisetum littoraJe Kuhlew-cin. This species, according to- 

 Piper and Beattie in the Flora of the Northwest Coast, has been 

 previously reported on this coast only from British Columbia, 

 but is of wide distribution both in this country and Europe, and 

 is possibly to be regarded as a hybrid. 



2. Typha angustifolia L. Not mentioned by Piper & Beattie 

 in the work just cited, but abundant at Eugene, seventy miles to 

 the south. Another species of very wide distribution. Some of 

 the Lake Labish specimens are fully typical, and others seem to 

 represent intergrades between this species and T. latifolia; but 

 the narrower spike is maintained in all of them. 



3. Agrostis oregonensis Vasey. According to Howell this 

 occurs "in moist meadows about the foot of Mt. Hood, Oregon"; 

 but in Hitchcock's revision of the genus (U. S. Dept. Agr. Bur. 

 PL Ind. Bull. 68:46) it is reported from several stations in Wash- 

 ington, and from Salmon Prairie, Clackamas County, Oregon. 

 What Howell called ''A. attenuata Vasey" seems to be the same 

 species. 



4. Phragmites communis Trin. This cosmopolite might with 

 safety be included in the flora of almost any district in the Tem- 

 perate Zone, but seems to have escaped notice west of the Cas- 

 cades. It is common in marshes along the lower Columbia in 

 Clatsop County, Oregon. 



5. Car ex dives Holm. A rare species, which I have collected 

 at only one other station, on the south side of Mount Hood, at 

 4,000 feet elevation. 



6. Carex interior Bailey. This has perhaps been confused 

 with C. stellulata Good., of which Kukenthal makes it a variety 

 (var. scirpoides (Schkuhr) Carey). 



7. Carex aperta Boott. Common along the Columbia river- 

 bottoms in the region about Portland, where it is used for hay. 

 Howell's "C. bovina." Widely distributed in Washington, but 

 not previously reported from western Oregon except as above. 



8. Carex prairea Dewey. Widely distributed in North Ameri- 

 ca, but usually in limestone areas, which do not occur in any 

 part of the Willamette Valley. Not reported from Oregon, un- 

 less Howell's "C teretiuscula Good. var. prairea Britton" is 

 identical.
