1921] Fernald,— Expedition to Nova Scotia 105 



lower Delaware, but they are good, giving us Samolus floribundus, 

 Juncus acuminatus, the first east of the tidal reaches of the Penob- 

 scot, and Myriophyllum humile, again the first east of the lower 

 Penobscot. 1 



Continuing up the valley, we saw much of a Staghorn Sumach, 

 Rhus typhina, but here and, as we afterward noted, at some other 

 stations in Nova Scotia, the pubescence of the branches is remark- 

 ably short and scanty, sometimes nearly wanting. At other stations, 

 however, the pubescence is quite as long as we find it southward, so 

 that there seems to be no constancy in the Nova Scotia variation. 

 Somewhat north of Tusket (or Vaughan) Lake we again came upon 

 the Inkberry, Ilex glabra, which had so amazed Long and me when we 

 found it with Empctnnn nigrum in the bog at Meteghan. But here 

 it was dominant over a considerable area, not of bog, but of dryish 

 rocky barren, associated with Vaccinium pennsylvanicum, Myrica 

 carolincnsis and the same handsome Antennaria neodioica, var. grandis 

 which we had collected at Meteghan. 



Our time was used up and we had not reached Carleton, but we 

 were content with the afternoon's work and ready to return home. 

 On the way back from the Tusket valley we had seen at several 

 places roadside colonies of a tall Lupine, but our driver informed us 

 that at Chebogue Point lupines covered many acres of hillside. 

 Accordingly, on the afternoon of July 14 we drove to the Point to 

 see them, one of the famous sights of Yarmouth County, great 

 masses higher than one's head of blue-violet (occasionally pink or 

 white) lupines covering the dry roadside-banks for a tremendous 

 distance, two thoroughly naturalized species from northwestern 

 America, Lupinus nootkatcnsis Donn and L. polyphyllus Lindl., both 

 already known 2 as naturalized plants in the Maritime Provinces, 

 but here growing intermingled and apparently freely crossing. 



On the return Bissell took home the material already collected and 

 the rest of us walked from Rockville back to Yarmouth, Pease and 

 Linder by the eastern shore of the Chebogue peninsula, where they 

 found more Eleocharis rostellata and with it Galium trifidum, var. 

 halophilum Fernald & Wiegand, 3 thus proving that that northern 



> Nichols reports M. humile as characterizing the sandy margins of lakes on Cape 

 Breton (Nichols, Veg. No. Cape Breton, 350) but, as he now informs me, this record 

 was based on the common lake-margin M. tenellum.
