 wide, very entire. Peduncle enlarged towards the ex- 

 tremity. Calix partly hemispherical, consisting of many 

 series of shortish, imbricated, squarrose leaves Rays ma- 

 ny, neutral, golden-yellow, externally pubescent, dilated 

 towards the extremity, and deeply 3-toothed or partly 

 trifid. Uiscal florets very numerous, glandularly pubes- 

 cent, 5 or rarely 4-toothed, the base very singularly indu- 

 rated and corneous. Anthers bisetose at the base. Stigmas 

 subperfoliate. Receptacle corneous, very deeply and re- 

 markably favose so as entirely to include the seed with 

 its pappus! the cells 2 to 3 lines deep; intersections o< the 

 margins toothed. Seed sericeous, inversely conic; leaf- 

 lets of the pappus, linear-oblong, partly acute and entire, 

 connivent in a cylinder, as long as the seed. 



2. • muUiJlera. Stem branched, many- flowered, smooth 

 and striated; leaves narrow Imear, subcarnose and smooth; 

 segments of the calix and teeth of the corneous cellular 

 receptacle acuminated; pappus very short, cupulate. Hab. 

 On the sand-hills of the Altamaha, West Florida — Dr. 

 BaUlwyn. Obs. Perennial? stem 3 or 4 feet high, terete,

 toothed. Seed immersed, sericeous, inversely and acu-
