Casselman, Ont. [J. M. Macoun.) T. perfoliatum is repre- 

 sented in the herbarium of the Geological Survey by speci- 

 mens from Belleville and Churchville, Ont. 



EuPATORiUM BOREALE, Greene, Rhodora, vol. iii, p. 83. 



Stout, erect, 2 feet high or more, glabrous except as to the 

 inflorescence : leaves ample, very thin, dark-green, feather- 

 veined, the veins not light-coloured, 3 or 4 inches long, often 

 3 inches broad towards the base, broadly subcordate-ovate, 

 abruptly acuminate, coarsely and evenly serrate, the serra- 

 tures 20 to 25 on each side, some of the larger with a second- 

 ary tooth ; petioles ^ to i ^ inches long, somewhat ascend- 

 ing: cymes terminal, but with one pair from the axils of the 

 uppermost leaves : peduncles and pedicels rather densely 

 pubescent, but involucres glabrous, their bracts thin, only 

 obscurely striate ; tips of the corolla-teeth somewhat hairy: 

 achenes dark-brown, sharply thin-angled, the angles of those 

 of the outer series remarkably setose-hispidulous, the surface 

 glabrous. 



Represented in our herbarium by specimens from Bass 

 River, Kent Co., N.B., collected by Prof. J. Fowler. Most 

 of what has been taken to be E. ageratoides in Eastern Canada 

 is probably this species. 



SoLiDAGO PRUiNOSA, Greene, Pittonia, vol. iv, p. 70. 



Erect, 3 feet high or more, very leafy up to the dense 

 short, pyramidal panicle of short, spreading or slightly recurved 

 abruptly ending- and obtuse racemes of rather large heads: 

 leaves ascending, 2 inches long, elliptic-lanceolate, acute or 

 acuminate, slightly but evenly serrate from near the base to 

 near the apex, distinctly 3-nerved and canescent op almost 

 hoary on both faces with a dense, rather soft puberulence or 

 pubescence: pedicels and branches of the inflorescence almost 

 tomentulose : bracts of the more than middle-sized involucre 

 in about 3 series, the short outer ones subulate-linear, the 

 inner long ones also visibly narrowed from base to apex but 

 obtusish; flowers apparently light yellow.
