420 SYNGENESIA— POLYGAM.-SUPERF. Conyza. 



rets. Seed-vessel none, except the permanent, conver- 

 ging, dry calyx, beset with the prominent tips of the 

 scales. Seed oblong, uniform and perfect in all the florets. 

 Down simple, sessile. Recept. slightly convex, tubercu- 

 lated. 

 A numerous, herbaceous or shrubby genus, of which our 

 only British species is the type, many of the foreign spe- 

 cies requiring examination. Gaertner remarks that if 

 this genus had radiant marginal^o;-^^^, it would not differ 

 from Aster.

In chalky or limestone countries frequent, or in woods on a marly 

 soil. 



Biennial. Jidy, August. 



Root tapering, fleshy, much subdivided underground, though sim- 

 ple at the crown. Herb soft and downy, bitter, somewhat aro- 

 matic, with a portion of mucilage. Stem upright, angular, leafy, 

 2 or 3 feet high, terminating in a corymbose, leafy, many-flow- 

 ered panicle. Leaves elliptic-lanceolate, veiny, variously cre- 

 nate ; radical ones large, tapering down into bordered foot- 

 stalks j the uppermost often entire. Fl. dull yellow. Tips of 

 the cahjx. scales green, leafy, recurved. 



The radical leaves bear some resemblance to those of Foxglove, 

 but when rubbed, are readily distinguished by their "aromatic 

 scent. 



The name of Flea bane, more properly Fly-bane, has been applied 

 to this plant ; but the still more correct synonym of its Latinized 

 Greek appellation would be Gnat-bane. The genus Erigeron is 

 however the real Fly-bane, some of its viscid species, dipped in 

 milk, being used in the south of Europe to catch the various little 

 winged insects, so troublesome in warm climates.
