15- Verbena officinalis L. One large clump near the "cradle" 

 has persisted. This has been found well established in the 

 village of St. Paul, Marion Co. 



1 6. Matricaria inodora L. Established over the entire area, 

 and escaping to the adjoining territory. 



17. Senecio Jacohaea L. Also thoroughly established — con- 

 tinues to flower throughout the year, much like S. vulgaris of 

 the gardens. 



18. Artemisia vulgaris L. The most abundant species of the 

 area, forming dense thickets. A less-branched form, with the 

 leaves mostly entire, occurs in Lower Albina. 



19. Carduus nutans L. Stubbornly persisting over the entire 

 area. 



20. Franseria hipinnatifida Nutt. Prostrate on the sandy 

 areas. Although this species is not uncommon on the coast 

 of Oregon, where it is clearly indigenous, it is worthy of note at a 

 distance of 100 miles from the sea, and as a component of a flora 

 otherwise foreign. 



A number of other species included in the original list have 

 reappeared sporadically now and then since the first report; 

 but they can hardly be regarded as sufficiently well established 

 to withstand the vicissitudes that this plant-society seems 

 called upon to encounter in the near future.
