Casselman, Ont. (/. M. MacoJin.) 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. in, 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}4 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 K ageratoides in Eastern Canada 

 is probably this species. 



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



Erect, ^ 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 or 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.
