252 PLANT NOTES FROM TADOUSAC 



large patches of Cnicus arvensis, Epilobium spicatum, and great 

 masses of the gorgeous yellow heads of Sonchus arvensis, while in 

 places Vicia Cracca covered the grass and low shrubs with a mantle of 

 blue. After a ride of nearly three hours, we alighted at our destination, 

 the little village'of Notre Dame du Lac, prettily situated on the curving 

 shore of Lake Temiscouata. 



Two lists of plants from this region have already appeared in the 

 Bulletin, the first by John I. Northrop, in November, 1887, the 

 second by Henry M. Ami, in May, 1888. 



On my previous visit, in one place near the shore, I collected an 

 exotic labiate, which was not determined as the specimen was in fruit, 

 but this year we found the same species, now evidently well established 

 and holding its own in a dense growth of Galeopsis Tetrahit and A ma- 

 rantus. It has curious one-sided spikes of blue flowers, and a peculiar 

 lemon-like odor. We sent some specimens to Dr. Britton, who wrote 

 in reply that it was Elsholtzia cristata, a native of Siberia, and belonged 

 near our genus Collinsonia. We found it growing in a clearing near 

 a mill, and there is no doubt but that it has been introduced. Still, 

 there are no records of its ever being cultivated, and how it reached 

 this out-of-the-way spot is a mystery. 



Near by on the banks of a brook Listera convallarioides grew 

 abundantly, and on the hillside above we found a few specimens of 

 Pyrola chlorantha. Great beds of Cornus Canadensis grew here, as 

 almost everywhere in Canada, and we noted that here, as elsewhere, we 

 could not find a single four-leaved plant that bore a flower. We had 

 been struck with this fact while botanizing in the White Mountains, 

 and had made it a special point of observation all summer, but out of 

 the hundreds of plants which we examined not one exception did we 

 find to this rule. 



One day we took our canoe and paddled some three miles down the 

 opposite shore of the lake and here, growing among the moss along a 

 little brook, we found the rare Selaginella spinosa, looking very much 

 like a delicate Lyco podium. Farther up the lake on the way to Mt. 

 Wissick we found a number of plants of Equisetum littorale. The speci- 

 mens have since been carefully examined and compared with those so 

 named by Dr. Morong, and they are undoubtedly the same species. 

 On our way to Mt. Wissick we passed over a shallow portion of the 

 lake, and a better place to collect water plants could not readily be
