leaves or the membranes connecting them appear always to show 

 at least some vestiges of ciliation, while in S. longipes the leaves are 

 neither so long nor relatively so narrow as they are in S. glauca. 

 Since the receipt of the specimens from Judge Churchill, S. glauca 

 from the same locality has been sent to the Gray Herbarium by Mr. 

 John Murdock, Jr. — B. L. Robinson. 



Some Plants new to the Flora of Maine. — In company with 

 a fellow botanist, Mr. F. M. Billings, I went on an exploring trip 

 September 7th, 1903, which proved a veritable red letter day in the 

 botanical line for us both, as in addition to securing many plants 

 which we knew to occur in the vicinity, though we had previously 

 never personally collected them, we were fortunate enough to secure 

 a few which could not be identified by a most rigorous search of the 

 botanical literature at our command. Our usual resort in such cases 

 is Mr. M. L. Fernald of the Gray Herbarium, and to him the puz- 

 zling specimens were sent for identification. A species of which Mr. 

 Billings had secured a single specimen the year previous, growing in 

 some ballast left by an Italian vessel, was found quite abundant in 

 the same locality this season, and on the day in question we secured 

 good specimens. Mr. Fernald pronounced this plant to be Mercuri- 

 alis annua L. and reported that to his knowledge it had never before 

 been recorded from Maine. On the side of a steep railroad embank- 

 ment Mr. Billings discovered a low spreading prostrate plant which 

 was then almost entirely out of bloom. It was quite abundant and 

 seemed to have been established there for at least one season pre- 

 viously. Mr. Fernald pronounces this plant to be Arichusa arvalis 

 Reichenbach, and he adds that it is apparently not recorded in Amer- 

 ica. On September 30th, Mr. Billings brought me specimens of a 

 plant which Mr. Fernald pronounces to be Galinsoga parvifiora var. 

 hispida DC. These were growing in a waste spot where rubbish and 

 other miscellaneous material was being constantly dumped and might 

 easily have been introduced with material used in packing crockery 

 ware, as such material consisting of straw and similar matter is 

 dumped in this locality. September 30 and October 4th 1 collected 

 specimens of a Valerian growing in waste places where it might easily 

 have been introduced with refuse from gardens. Mr. Fernald pro-
