304 Class XIX. Order II. 



tire, three nerved, glabrous ; corymbs terminal ; ligules 

 as high as the disc. Ait. 



This species of golden rod is distinguished from the succeed- 

 ing ones, by its inflorescence. Stem tall, leafy, branching. Leaves 

 numerous, long, and narrow, marked for their whole length with 

 three distinct nerves, very rough on the edge. Flowers yellow, 

 in large, Hat topped corymbs, composed of small heads. Ray 

 very short and obscure. The whole plant is pleasantly aro- 

 matic. Woods and road sides, in low ground. August, Septem- 

 ber. Perennial. IK 



SOLIDAGO ODORA. Sweet scented Golden Rod. 



Bigelow, Medical Botany, PI.xx. 



Stem nearly smooth, leaves linear lanceolate, entire, 

 smooth, with a rough margin, and covered with pel- 

 lucid dots. Racemes panicled, one sided. 



This has a smooth appearance, and is among the smaller 

 species of its family. The root is woody, much branched and 

 creeping. Stem slender, from two to three feet high, smooth 

 or slightly pubescent below, pubescent at top. Leaves linear 

 lanceolate, closely sessile, broad at base, entire, acute, with only 

 the midrib distinct, rough at the margin but otherwise smooth, 

 and covered with pellucid dots like Hypericum perforatum. 

 The flowers grow in a compound, panicled raceme, with each 

 of its branches supported by a small leaf These branches or 

 peduncles are very slender and rigid, each giving off a row 

 of ascending, downy pedicels, with small linear bractes at 

 their bases. Scales of the calyx oblong, acute, smooth, or 

 slightly pubescent, the lower ones shorter and closely imbri- 



then in flower. Among the species there are a vast variety of hybrids and 

 subspecies which the labours of botanists have not yet been able to reduce 

 under permanent characters, though names without number have been ap- 

 plied to fugitive varieties. The single species found in Great Britain is 

 acknowledged to be one of the most difficult plants " to define or under- 

 stand." The same remark is applicable to a great part of the American 

 species. In this work I have inserted only the more distinct or leading spe- 

 cies, from which a great part of the others in this vicinity are probably 

 .Descended.
