east to Queens County; but, although clearly belonging with J. sub- 

 caudatus, the Nova Seotian plant differs in having a shorter peri- 

 anth with broader and greener uncorrugated sepals and thus con- 

 stitutes an endemic Nova Seotian variety. 



There is a little sand- and cobble-bordered lake by the railroad 

 about a mile south of Lake Annis. We had more than once specially 

 noted it as a promising spot, consequently on July 29, Bean, White 

 and Linder went there to try their luck. They soon learned that 

 this is Jassy Lake a,nd if we had not begun to be satiated with Utri- 

 cularia subulata, Subularia aquatica and Myriophyllum tcnelhim, 

 would rank as a good spot. They brought back Solidago canadensis, 

 which sounds uninteresting, but singularly enough, during the whole 

 summer we did not see this characteristic Canadian species in south- 

 ern Yarmouth County nor in Shelburne and Queens Counties, its 

 place in swampy thickets being there preempted by another plant 

 not yet i i flower but decidedly not S. canadensis. They also had 

 a very dedicate Utricularia, the material all sterile but in the capillary 

 forking of its leaves and in its bladders closely matching U. gibba. 



The gl mpse of Trefry's Lake which Pease and I had got two 

 weeks earlier had stayed vividly in my mind throughout that crowded 

 and ever-changing fortnight and Long was not averse to visiting its 

 shores, so, while the others were at Jassy Lake, he and I spent one of 

 the happiest days of the summer, making an almost complete circuit 

 of the lake. The vegetation had greatly changed in two weeks and, 

 owing to frequent rains and prolonged fog, the narrow beach had 

 become a most invisible. As we started in we came upon Sieglingia 

 decumbent* in the most natural spot of the summer, at the upper border 

 of the beich next :he thicket, but there was a cow-path nearby so 

 that here as elsewhere the evidence of its native character was in- 

 conclusive. 



The very distinct goldenrod of the subgenus Euthamia, which we 

 had been watching at other lakes, was now in good condition in the 

 shallow water, though the plants higher on the beach were not yet 

 flowering; a beautiful little plant with tall, simple stems rarely 

 branching at the summit and with very fleshy and firm, dark-green 

 mostly 1 -nerved, linear-oblong to linear-lanceolate, blunt or merely 

 acute, ere:t leaves, and with the deep-yellow heads so densely crowded 

 as to make the corymb appear like a handsome golden button com- 

 monly on y 1 or 2 cm. in diameter, or in extreme plants like a few
