218 Rhodora [NOVEMBER 
Linaria canadensis (L.) Dumont. Abundant throughout, the plants 
remarkably vigorous and large. I will quote from my journal of 
August 27, 1912, “It is interesting to see the conduct of some of the 
invading plants. They behave as many species have done and are 
still doing, when introduced into a new region, taking possession with- 
out resistance and densely covering large tracts in profuse abundance. 
Lactuca scariola, var. integrata, Erechtites hieracifolia, Linaria cana- 
densis are illustrative. These plants grow over the marshes, that 
were once covered by high tides, in the greatest profusion. It is 
strange to see Linaria canadensis so thickly growing. I saw in one 
place, to-day, a large patch, a few rods across, that had been cut down, 
and that would make, if stacked, a good-sized cock.” 
Veronica peregrina L. A single plant on the west side. 
Plantago major L. Occasional in scattered localities. 
Plantago decipiens Barneoud. Scattered over the marsh, forming 
colonies. 
Sambucus canadensis L. Several vigorous plants on the west side, 
5 to 6 feet high. 
Eupatorium. purpureum. L., var. maculatum (L.) Darl. A single 
large plant not far from the center of the marsh. 
Solidago sempervirens L. Abundant at the north end, and scattered 
throughout. 
Solidago rugosa Mill., var. aspera (Ait.) Fernald. (Ruopona xvii. 
7,1915). Several plants at the north end. 
Solidago canadensis L. Sparingly near the center and at the north 
end. 
Solidago altissima L. Several plants in the north section. 
Solidago graminifolia (L.) Salisb. Several plants in two localities 
in the northern half. 
Aster vimineus Lam. A number of plants scattered over the marsh. 
Aster lateriflorus (L.) Britton. A single large plant in the middle of 
the marsh. 
Aster novi-belgii L. Scattered plants throughout. 
Aster subulatus Michx. Abundant throughout, especially on the 
borders of the ditches. It reaches the height of 4 feet. 
Erigeron canadensis L. Scattered over the densely compact grassy 
areas, including Black Grass, Juncus Gerardi. 
Baccharis halimifolia L. Well developed staminate and pistillate 
shrubs, some 44 feet high, are growing at the north and south ends
