sessile, lanceolate ; racemes mostly simple, short ; heads large, with conspic- 

 uous rays. A very fine goldenrod abounding in woods on the sides of the 

 White Mts., and at Franconia Notch. It is remarkable for the long, slender 

 stalks of the lower, ovale leaves, and for the large, deep yellow flowers which 

 exceed in size those of all other species. Stem 1 — 3 feet high, racemes 

 axillary and terminal, usually in a thyrse-like panicle. Aug. 



13. S. VlRGAUREA. 



Slem flexuous, furrowed, pubescent at top ; stem leaves lanceolate, serrate ; 

 loicer ones oval, attenuated at both ends; race^nes erect, ray elongated, flowers 

 large. This is the only species common to the two continents. One of its 

 numerous varieties is seen scattered here and there on the lower summits of 

 the Wliite Mts., scarcely on Mt. Washington peak. The flowers are very 

 few, often one only, but larger than those of most other species, and of a 

 rich, golden yellow. Stem often purple, 2 — 3 inches high, simple, with 

 axillary and terminal flowers. Aug. European Goldenrod.
