occidentalu, some of the trees being the largest we had ever seen. 

 In the cleared places were large patches of Cnicus arvensts, 

 Epilobimn spicatiim and great masses of the gorgeous yellow 

 heads of Sonchtis 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 httle 

 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 TetraJiit and Amaraniiis, 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 cristaia, a native of Siberia, and belonged near our 

 genus Collmsonia, 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 cJiloi^antha. Great beds of Coriiiis Cana- 

 densis grew here, as almost everywhere in Canada, and we noted 

 that here, as elsewhere, we could not find a smgle fonr-leavcd 

 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 Selagmella 

 spinosa^ looking very much like a delicate Lycopodium, Far- 

 ther up the lake on the way to Mount Wissick we found a 

 number of plants of Equisctitm littorale. The specimens have
