324 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, leaf)', branching. 

 Leaves numerous, long and narrow, marked for their whole 

 length with three distinct nerves, very rough on the edge. 

 Flowers yellow, in large, flat topped corymbs, composed of small 

 heads. Ray very short and obscure. The whole plant is plea- 

 santly aromatic. — Woods and road sides, in low ground. — Au- 

 gust, September. — Perennial. 



SoLiDAGO Odora. Swect scented Golden Rod. 



American 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 Hipericum 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 imbricating the rest. Florets 

 of the ray few, with oblong, obtuse ligules. Those of the disc 

 funnel shaped, with acute segments. Down simple to the naked 

 eye, feathery under the microscope. Seeds oblong. — Woods and 

 fields. — September. 



mark is applicable to a great part of the American species. In this 

 work I have inserted only the more distinct or leading species, from 

 which a great part of the others in this vicinity are probably de- 

 scended.
