464 SYNGENESIA [Astrhoibs* 



Kraut-leaved Aster. 



Stem I to 2 or 3 feet high, somewhat flexuose, striate, smooth below, paniculate 

 at summit, with the branches pubescent in lines. leaves 1 to 3 or 4 inches long* 

 and half an inch to 2 and a half inches wide, acuminately tapering at apex, 

 serrate (the acuminalion entire), slightly scabrous above, the under surface some- 

 what pilose, often smooth,— the lower leaves cordate and rather unequal at base, 

 on petioles \ to 2 inches long, with narrow ciliated margins,— the upper leaves 

 smaller, ovate, or spaiulate-ovatc, and lanceolate, contracted at base to short 

 margined petioles. Heads of flowers rather small, numerous, in somewhat race- 

 mose or compact oblong panicles ; bracts small ; involucre smoothish, the leaflets 

 linear-oblong, rather acute, often purple at apex, scariousand minutely pubescent- 

 ciliate on the margin ; rays about 12, pale purple, or sometimes nearly white. 

 Akenes smooth. 

 Hab. Woodlands : frequent. Fl. September. Fr. October. 



Obs. This is somewhat variable in its minor characters ; but it is the A. cord? 

 folius, of the American Botanists,— and, 1 suspect, will scarcely prove to be dis- 

 tinct from the Linnaan species of that name,— although Nees von Esenbeck so 

 considers it. 



5. A. pantculatus, Ait. Stem smooth, paniculately branched, 

 branches erect, racemose-thyrsoid ; leaves oblong- and ovate-lanceolate, 

 serrate, attenuate at apex, the lower ones subcordatc, on long petioles, 

 the petioles with narrow smoothish margins ; involucre loosely imbri- 

 cate, smoothish, the leaflets subulate-linear. Beck, Bot. p. 187. 



Paniculate Asteii. 



Stem 2 to 3 or 4 feet high, striate, smooth, with numerous erect branches above. 

 Radical leaves 2 to 5 inches long, and 3 fourths of an inch to 2 inches wide, ovate- 

 oblong, acuminate, serrate, more or less cordate at base, somewhat pilose on both 

 sides, especially beneath, and ciliate on the margin, the petioles 2 to 6 inches long, 

 striate, smooth, with narrow margins ; stem-leaves gradually smaller, ovate-lance, 

 olate, and oblong-lanceolate, with a slender tapering apex, serrate, narrowed 

 rather abruptly at base to a margined petiole,— those on the branches sessile, 

 lanceolate, or linear-lanceolate, acute at each end. Heads of flowers rather small, 

 numerous, racemose-paniculate, racemes often compound, or thyreoid, on the 

 branches ; branches and pedicels pubescent ; bracts subulate-lanceolate ; involucre 

 smoothish, the leaflets subulate-linear, acute, with green keel and scarious 

 margins ; rays pale purple, or bluish, sometimes white ; disk yellow, or brown. 

 Akenes smooth. 

 Hab. Woodlands; along Brandy wine: frequent. Fl. August— Sept. JFV. Octo. 



Obs. This is the A. paniculatus, of Muhlenberg' 1 s Herbarium, but not of Nuttall ; 

 the latter being nothing but a var. of A. undulatus. The plant inserted in my 

 Catalogue as " A. lanceolatus ? " appears not to be distinct from this. 



6. A. undulatus, L? Stem roughish-pubescent, paniculate above, 

 branches spreading, leafy ; radical leaves cordate, serrate, petiolate, 

 stem-leaves ovate, subentire, with broad-winged petioles, the upper ones 

 sessile, all subtomentose-pubescent beneath, scabrous above ; involu- 

 cre imbricate, pubescent, the leaflets lance-oblong. Beck, Bot. p. 186«
