On the muddy sea coast, and in salt marshes, plentifully. 



Perennial. August, September. 



Root of many long stout fibres. Herb smooth, rather glaucous, 

 varying extremely in size, and in quantity of flowers, but 

 scarcely so distinctly diflering in any case as to make a well de- 

 fined variety. Stem round, hollow, generally erect, 2 or 3 feet 

 high, leafy and many-flowered ; often recimibent, or partly as- 

 cending, slightly leafy, with 3 or 4 flowers only, and those often 

 destitute of rays. Leaves very smooth, coriaceous ; the upper 

 ones sessile, linear-lanceolate; radical ones stalked, larger, 

 more elliptic-oblong, tapering at each end, always entire as far 

 as I have observed, though Willdenow describes some slight ser- 

 ratures near the point. Fl. large and handsome, with a yellow 

 or orange disk, and numerous, spreading, elliptic- oblong rays, 

 3-toothed at the extremity, generally of a bright blue, occa- 

 sionally white, never revolute. Seeds compressed, fringed at 

 the edges. Down reddish, minutely rough.

Common Cal. oblong, imbricated ; scales oblong, narrow, 

 pointed, straight, converging. Cor. compound, radiant ; 

 Jlorets of the disk numerous, j^erfect, tubular, with 5 equal 

 spreading segments ; those of the radius from B to 10, 11- 

 gulate, elliptic-oblong, 3-toothed. Filam. in the tubular 

 florets only, capillary, short. Anth. in a cylindrical tube. 

 Germ, in all the florets fertile, cblong. Style thread- 

 shaped. Stigmas 2, revolute ; those of the disk rather 

 thicker. Seed-vessel none, but the unchanged calj'X. 

 Seed obovate-oblong. Doxvit sessile, capillary. Recept.
