small hill overlooking the depot, and used as a municipal park. 

 Cars and pedestrians are constantly entering from foreign 

 localities thus giving ample opportunity for the accidental 

 introduction of foreign species. Spencer's Butte, even though 

 more than six miles from Eugene is a favorite hiking and camp- 

 ing spot for people about Eugene. In both of these localities 

 C. echinatus L. was found growing on dry, exposed slopes. 



Thus far it seems plain that it is an introduced species, but 

 since the publication of these papers the writer has found it 

 abundantly established on dry sunny hillsides in the foot-hills 

 of the Cascade Mountains some twenty miles southeast of 

 Eugene, far from the usual route of travelers. These out- 

 lying stations were in all cases separated from the stations at 

 Eugene by miles and miles of dense timber and several rivers. 

 It seems incredible that it should have been artificially intro- 

 duced in these widely separated localities. Even more incredible 

 seems the possibility of its being a rare native of these foot- 

 hills. 



Possibly in years past some solitary hunter or prospector 

 carried the seeds into the hills in grain for his horse, and yet 

 it seems unlikely that grain would be carried for stock in a 

 region where green fodder is comparatively easy to find. 



The old military road, over which some of the immigrants 

 entered the Williamette valley in years past, follows up the valley 

 a few miles from these outlying Cynosurus stations. Perhaps 

 some wondering straggler of the immigration trains caused the 

 introduction of this grass while feeding his horse. 



At all events, whether it was introduced by prospectors, 

 hunters, or immigrants, C. echinatus L. is firmly established in 

 the foot-hills southeast of Eugene. The writer has for several 

 seasons seen this interesting grass growing so profusely along 

 roadsides near Eugene, that it had been cut and shocked for hay. 

 Stock must indeed be hungry to eat Cynosurus hay with the 

 quantity of dry, wiry empty glumes which occur on each spikelet. 



R. V. Bradshaw cites specimens (Torreya, Vol. 21, page 83) 

 in the United States National Herbarium to show the wide 

 range of this species, but he points out its extreme rarity in 

 North America, but four localities being represented. They 

 are as follows: — British Columbia; Vancouver Island; Eugene, 

 Oregon; Marion Co., California.
