SYNGENESIA. SUPERFLUA. 89 



S-. KETEROPHYLLiTM. Ph. radical leaves round-ovate, deeply toothed, petiolate; cauline lanceolatej acute- 

 ]Fl. Middle of June, and after- Fr- mat. Beginning of August, and after. 



Hal). Pastures, &c. Patton's: frequent. About 3 feet high: rays pale purple, or white. 



-E. CANADENSE. Ell. Stem hispid, paniculate; leaves lance-linear, ciliate; c.ilyx cylindric. 

 F((/gro— Horse-weed- Bulter-weed. Hog-weed. Piide-weed- Canadian Flea-bane. 

 .Fl. Beginning of Angust, and after. Fr mat. Middle of September, and after. 



Hah- Fields, &c. every where common. 6 inches, to4feethigh: flowers white, small, numerous. 



Obs. This troublesome weed is reputed to possess medical virtues; as, indeed, are all th; preceding,— 

 except perhaps E- strigosum. This species is often bruised, and applied to fresh incised wounds, in pop- 

 ular practice— when a simple bandage, of clean rag, v.'ould probably be quite as beneficial. 



295. SOLIDAGO. Nutt. Gen. 660. 

 [Lat. solido, to make firm, or to heal; from its supposed vulnerary properties.] 

 Cal- imbricate; scales appressed. Radial florets about 5. Pappus simple, pilose- Reccpt. punctate. 

 § 1. Racemes secund, recurved. 



S. RUGOSA? Ell. Stem hispid; leaves lanceolate, scabrous, rugose, serrate; panicle spreading. 

 Fl. Latter end of August, and after- Fr. mat. Beginning of October. 



JIab. Low grounds: Patton's, &c. frequent. 3 to 6 feet high: flowers yellow. 



Obs. There seems to be two or three varieties of this species. 

 S. scABRA- Ph. Stemsulcate; leaves oblong, tapering at each end, glabrous ahove, scabrous beneath, 

 Fl- Latter end of August. Fr. mat. Beginning of October. 



Hab. Borders of thickets; Bath, &c. frequent. 2 to 5 feet high: flowers yellow. 

 S- PYRAMiDATAl Ell- Stem subterete, striate; leaves lance-oblong, subenlire, margin ciliate. 

 Fl. Latter end of July, and after. Fr. mat. Latter end of September. 



Hab. Sterile old fields, &c. frequent. 2 to 3 feet high: flowers yellow. 



06s- I have the authority of Mr. Schweinitz for this species; but IVom its prevalence here, I incline to 

 think it must have been known to Dr. Muhlenberg, and other botanists, under another name. 



S. NEMOHAi.T=. Ell. Stem tomentose; leaves lanceolate, tapering at base, lower ones subcuneate. 

 Fl. Middle of September. Fr- mat. Middle of October. 



Hab. Low grounds: Patton's, &c. frequent. 2 to 3 feet high: flo .vers yellow.

FJ- Middle of September. Fr. mat. Middle of October. 



Hab. Swamps, and low woodlands: Patton's: frequent. 2 to 4 feet high: flowers yellow. 



§ 2. Racemes erect. 



S- BicoLOR. Ell- Hairy-pubescent; leaves elliptic, acute, tapering at base, lower ones serrate. 



Fl- Latter end of August- Fr. mat- Last of Septem-bcr. 



Hab- Woodlands, and low grounds: frequent. 1 to 3 feet high : flowers yellowish white. 



S. ERECTA? Ell. Stem and peduncles roughish-pubescent; leaves lance-oval, acute at each end- 

 Fl- Latter end of August- Fr. mat. Beginning of October. 



Hab. Woodlands: Bath, &c- frequent. 1 to 2 feet high: flowers pale yellow. 



Obs. Mr. Schweinitz pronounced tiiis to be S- erecta. Some of the lower leaves are a very broad 

 Ov«l, tapering abruptly, at base, to a marginate petiole. To me it seems to approach the preceding, in habit. 



S- LANCE0L.4.TA. Pk. Stem branching; leaves lance-linear, entire; corymbs terminal, fastigiate- 



Synon. S- graminifolia. Ell. Euthamia graminifolia. Nutt.

S- ciEsiA- Ph- Stem smooth, glaucous; leaves lanceolate, acuminate, serrate; racemes axillary. 



Pw/g-o— Golden rod- 



Fl. Beginning of September, and after. Fr. mat. Middle of October. 



J^ab. Woodlands: common. 1 to 3 feet high: llowers yellow. 



Obs- All the species are known by the common name of Golden rod; but this one is so called by way of 

 eminence, in this vicinity. It is reputed rnedicin.Tl, by some dealers in simples, who allege that it is a rem- 

 edy tor the bite of snakes, &c. but I apprehend its virtues are unimportant. 



We have, doubtless, other species of this difficult genus; but the foregoing are all that I have been able, r.s 

 yef, td determine with any degree of satisfaction,— even with the assistance of my botanical friends-
