1906 Knight, — Some new Records of Maine Plants 99 



Ceanothus americanus L. There seem to be no recent records of 

 this plant being collected in Maine. We have known a station by the 

 Penobscot River near Bangor for several years, and July 30, 1905, Mr. 

 Billings found another station for the plant, also on the river-bank 

 some half a mile from the first station. 



Heracleum sphoridylium L. Mr. Billings and I found lusty plants 

 of this growing in the rear of a warehouse on a wharf along the water 

 front, Bangor, July 8, 1905. 



C henopodium polyspermum L. We collected it in sandy soil at edge 

 of a wharf on the same day as the preceding species. 



Galium unollugo L. Very abundant at one station, Bangor. 



Andromeda licjustrina Muhl. I collected this on a "floating bog" 

 at Pittsfield which is very near its northeastern limit of distribution 

 in Maine. It is common the other side of the Kennebec River. 



Physocarpus opulifoiius Maxim. I collected this in a thicket near 

 a brook, June 30, 1905, in Brewer. Years ago Aaron Young collected 

 this, as shown in the Gray Herbarium, on " Banks of streams, Bangor" 

 but we have been unable to find his original station and are rather in- 

 clined to believe the plant has been exterminated by cultivation. 



Datura stramonium L. Mr. Billings found a few plants in newly 

 deposited ballast along the Maine Central Railroad near Bangor, Aug. 

 26, 1905. 



Bidens beckii Torr. Mr. Billings found one plant in bloom at Pu- 

 shaw Pond in August, and I collected sterile material later on but could 

 find no flowers. The plants were very numerous in a small slug- 

 gish brook. 



Sedum acre L. One plant growing by roadside, Bangor, July IG, 

 1905. 



Saponaria vaccaria L. Several plants were collected by Mr. Billings 

 along shore of river, Bangor, July 15, 1905. 



With the exception of the Datura, Bidens, Saponaria and Sedum, 

 specimens of all the plants have been submitted to Prof. Fernald for 

 verification, and my thanks are due him for his kindness. 



Bangor, Maine.
