Further Notes on Solanum rostratum and Hieracium prae- 

 altum in Maine. — The notes by Mr. (). W. Knight on the appear- 

 ance east of the Kennebec of Solanum rostratum (Rhodora, hi. 

 276) and Hieracium praealtum (Rhodora, iv. 61) may be supple- 

 mented by the following observations. 



In August, 1900, Solanum rostratum, the buffalo Bur, was noticed 

 in a border of phlox on the campus of the University of Maine at 

 Orono. It was probably introduced there in seed purchased in 

 western New England. The eastern distribution of the Buffalo Bur 

 seems to be almost wholly through commerce ; and in Maine it was 

 first detected at Buxton where western grain had been screened. 



While visiting the famous station for Mountain Laurel, Kalmia latt- 

 folia, at Carmel, on July 1, 1898, the writer observed the King-Devil 

 Weed, Hieracium praealtum, sparingly established in an adjacent 

 meadow. The following note was made: "Sparsely growing in a 

 meadow with the Mouse-ear Hawkweed, Hieracium pilose/la, and 

 evidently mistaken for that species." This observation was recorded 

 in an article by the writer on the weeds of Maine and the bad 

 character of the weed was commented upon. In one year it had 

 spread more than had the Orange Hawkweed, H. aurantiacum, in 

 twenty. The Carmel station is some twenty miles southwest of that 

 recorded by Mr. Knight; and its observation in Carmel in 189S 

 supports his supposition "that the plant must have been established 

 in this locality for a number of years to have become so abundant." 



This Carmel station furnishes a connecting link between the well- 

 known Gardiner locality seventy-rive miles southwest (recorded by 

 I). H. Knowlton in 1895), and the Kenduskeag and Corinth stations 

 of Mr. Knight about twenty miles northeast. These stations indicate 

 a most rapid northeastern invasion of one hundred miles in six years, 

 — an invasion to be regarded with dread by the agriculturist, since
