The Greenville Meeting. 



By Arthur H. Norton. 



The twenty-third annual meeting of the Josselyn Botan- 

 ical Society was held at Greenville Junction, Maine, at the 

 southwestern extremity of Moosehead Lake, July 31 to Aug- 

 ust 4, 1917, with headquarters at the Piscataquis Exchange. 



The meeting took place during a period of great heat, 

 daily relieved by heavy thunder showers, which coursed down 

 the lake and the Kennebec valley. Fortunately these show- 

 ers were so timed that they contributed materially to the 

 enjoyment of the grandeur of the vast wilderness of moun- 

 tain-studded forest without delaying the work of collecting. 



The forest appeared almost unbroken, consisting of white 

 pine, with an abundance of red spruce, hemlock, white and 

 yellow birch, large-leaved poplar, and in low ground arbor 

 vitae. 



The shores of the lake were remarkably barren of aquatic 

 plants, Sagittarias , Potamogetons , Pontederia, Nymphaea, Nu- 

 phars and forms usually associated with them, and the semi- 

 aquatic heaths were almost entirely absent. This scarcity 

 may have been due to a rather recent raising of the water 

 level of the lake. 



Another matter of interest, to be noticed again, was the 

 scarcity of many common introduced weeds, which here were 

 confined to the vicinity of roadsides, tote roads, and especially 

 to the railroad tracks and yards. 



July 31st. The time of arrival was late, and only a brief 

 examination of the lake shores in the immediate vicinity of 

 the village was made. Among the plants noted were Sagit- 

 taria latifolia, vox. gracilis (very scarce), Alopecurus genicula- 

 tes, var. aristulatus (also scarce), Carex crinita, var. minor 

 (very common), and several ample mats of Polygonum am- 

 phibium.
