12. Solidago ulmifolia Muhl. Elmleaf Goldenrod. A very 

 slender glabrous or puberulent plant, 2-4 ft. high, simple or 

 with arched puberulent branches. Leaves thin, oblong to 

 eliptical-lanceolate, acute or acuminate at the apex and base, 

 sharply serrate, pinnately veined, slightly pubescent, the 

 lower and basal ones wider, 3-5 in. long, 1-1^ in. wide, narrowed 

 to margined petioles, the upper smaller and sessile. Heads 

 secund on the usually few elongated and often leafy branches 

 of the panicle; ray flowers small, deep yellow; bracts of the 

 involucre oblong-lanceolate, obtusish. Achenes pubescent. In 

 woods and copses. July-September. Rather general. 



13. Solidago neglecta T. & G. Swamp Goldenrod. Stem 

 glabrous or slightly rough above, simple, rather stout, 2-4 ft. 

 high. Leaves firm, the lower and basal ones lanceolate to 

 oblong-lanceolate, large, sometimes 12 in. long, acute, closely 

 serrate or serrulate, tapering to margined petioles, rough on the 

 margins; the upper smaller, lanceolate, acute, sessile, serrate 

 or nearly entire. Heads more or less secund on the short 

 branches of the thyrsoid panicle; rays 3-8, small; bracts of 

 the involucre thin, linear, obtuse. Achenes glabrous or nearly 

 so. In swamps and bogs. August-September. Wood, Madison, 

 Fairfield. 



14. Solidago juncea Ait. Plume Goldenrod. Stem glabrous 

 or nearly so throughout, rigid, rather stout, single or branched 

 at the top, 1^-4 ft. high. Leaves glabrous or rough, lanceolate 

 to oval-lanceolate, acute to acuminate, serrate or entire, the 

 upper ones smaller and sessile. Heads secund on the recurved, 

 branches of the usually spreading panicle; rays 7-12, small; 

 bracts of the involucre oblong to ovate-oblong, obtuse or 

 acute. Achenes glabrous or sparingly pubescent. In dry or 

 rocky soil. June-November. Rather general. 



15. Solidago arguta Ait. Cut-leaf Goldenrod. Stem simple, 

 rather stout, glabrous or sparingly pubescent above, 2-4 ft. 

 high. Leaves thin, pinnately veined, the lower and basal ones 

 broadly ovate-oval, short-acuminate, 3-16 in. long, 1-5 in. 

 wide, narrowed to margined petioles or subcordate, sharply 

 and coarsely serrate; the upper leaves smaller, sessile, ovate to 

 oblong, acute or acuminate, more or less serrate. Heads 

 secund on the lateral racemose branches of the terminal often 

 leafy panicle; rays 5-7, large; bracts of the involucre oblong, 

 obtuse. Achenes glabrous or nearly so. In rich woods. July 

 to October. Erie County.
