Also, A. paniculatus. Nutt. Gen. 2. p. 156, Not of Ait. JMuhl. &c. 



Uxdulate Aster. 



Stem 1 to 3 feet high, pubescent and roughish, often purple, paniculate and often 

 bushy at summit, the branches and branchlcts (or pedicels) leafy. Radical leaves 

 1 to 2 inches long, and about an inch wide, oblong-cordate, often obtuse, and some- 

 times reniform, serrate, pubescent, on striate pubescent slightly-margined petioles 

 1 to 3 inches long ; stern-leaves 1 to 3 or 4 inches long, and half an inch to 2 or 2 

 and a half inches wide, ovate, acuminate, mostly entire and slightly undulate on 

 the margin, scabrous above, more downy-pubescent beneath, abruptly contracted 

 at base into a broad-winged petiole, which is usually dilated and amplexicaul at 

 the insertion (the lower stem-leaves sometimes distinctly cordate at base, and oil 

 narrow petioles), the upper leaves oblong-ovate, sessile and amplexicaul. Heads 

 oftlowers middle-sized ; branches and pedicels pubescent, clothed with small 

 jancc-oblong acute leaves, or bracts; involucre pubescent, the leaflets lance- 

 oblong, acute, c.l.ate; rays pale violet-purple, or bluish ; disk yellow, becoming 

 purplish. Akcnes slightly pubescent, finally smuothish, 5-ribbed. 

 Hob. Dry woodlands; fence-rows, <fcc. common. Fl. Sept-Octo. Fr. Octo. 



Obs. The stem and leaves of this usually have a greyish appearance, by reason 

 of the cinereous pubescence. 



b. Homophyllousy—ov the leaves all of a similar form. 



7. A. prexanthoides, Muhl. Stem and branches pilose in lines 

 corymbose-paniculate; leaves spatulatc-lanceolate, acuminate, incised-' 

 serrate in the middle, auriculatc-amplexicaul at base, scabrous above 

 smooth beneath; involucre loosely imbricate, the leaflets linear, squar- 

 rosely spreading at apex. Beck, Bot. p. 185. 

 A. serotinus. FloruU Cestr. p. 91. Not of Willd. &c. 



PilEXAXTHKS-LIKE ASTER. 



Stent lor 2 to 4 or 5 feet high, angular-striate, often purple, smoothish, sometimes 

 t uberculate 9 or mur.cately scabrous, and usually with pilose lines decurrcnt from 

 the base of the leaves, corymbosely branched above, the branches conspicuously 

 pilose in lines. Leaves 2 or 3 to 6 or 8 inches long, and half an inch to an inch 

 and half or 2 inches wide, more or less spatulate-lanceolate, with an entire con- 

 spicuous acuminatum, inciscd-serrate in the middle, tapering entire and often 

 narrowed almost to a petiole below the middle, a little dilated at the base, sessile, 

 aunculate and amplexicaul, the upper surface and margin scabrous, smooth 

 benea h. Heads of flowers rather above the middle size, often numerous, in a 

 spreading corymbose panicle ; involucre minutely roushish-pubescent, the leaflets 

 linear, acute, spreading at apex; rays pale violet-purple, or lilac, sometimes 

 nearly white. Akenes cuneate-oblong, nerved, pilose, yellowish. 

 Hab. Low grounds; along Brandy wine .-frequent. Fl. Sept-Octo. Fr. Octo.

8. A. puincKus, L. Stem hispid, paniculate ; leaves oblong-lanceo- 

 late, acuminate, appressed-scrratc in the middle, sessile, amplexicaul, 

 scabrous above, smoothish beneath ; involucre loosely imbricate, the 

 leaflets subulate-linear, nearly equal. Beck, Bot. p. 184
