53- *Tilia europaea L. Thoroughly estabUshed at border of 

 woods by roadside, Gunter, Douglas Co., in the Cala- 

 pooias. 



54. Sidalcea Nelsoniana Piper. Not uncommon in dry ground 



about Salem. This is the "apparently undescribed 

 species" of my list in Torreya (18 : 28. No. 90). 



55. * Althaea rosea Cav. A common escape to vacant lots and 



waste ground, Salem. 



56. * Viola odorata L. Escaping to cultivated ground about 



Salem. This is the form with white single flowers. 



57. Viola orbiculata Geyer. Dry woods near timber-line on 



Mt. Jefferson. Previously collected in this region by 

 Gorman. 



58. ^Oenothera mollissima L. In shipyard, Linnton. An Argen- 



tinian species. 



59. Sphaerostigma andinum (Nutt.) Walp. On muddy shore of 



the Columbia on Hayden Island. 



60. Clarkia rhomboidea Dougl. Dry woodland on Parrott 



Mountain, three miles northeast of Newberg. 



61. Lomatium microcarpiim (Howell) C. & R. On a rocky ridge 



in the Calapooias, two miles northeast of Comstock, 

 Douglas County. Perhaps the first report since its 

 discovery at Roseburg. 



62. Arctostaphylos patula Greene. Dry slope of Mt. Jefferson, 



above Pamelia Lake. 



63. *Asclepias syriaca L. On vacant lots and street-parking, 



Salem. 



64. Phacelia calif ornica Cham. Dry soil along railroad. Cottage 



Grove. This is Macbride's forma vinctens (Contr. Gray 

 Herb. 49: 37. 1917); but as no such present participle 

 seems to occur in the Latin language, and it was evidently 

 Mr. Macbride's intention to use a form of vincire, to 

 bind or twine, it would not seem a violation of the Inter- 

 national Rules to substitute the form vinciens, and the 

 correction is accordingly proposed. 



65. Phacelia Bolanderi Gray. Rocky slope along the Pacific 



Highway in the Calapooias, one mile south of Divide, 

 Lane Countv.
