kviii GENERA. 



Order II. RADIATA:. 



The Tribes are : — 



1. Inule^. Branches of Style of tubular Florets convex, obtuse; upper part externally 

 pubescent. Gen. 426-429. 



2. AsTEKiNE^;. Branches of Style of tubular Florets flattened, somewhat acute, pubescent 



externally. Crest hair-like. Recept. naked. Gen. 430-438. 



3. GA1LINS0GE.E. Branches of Style of Tubular Florets with a tuft of glands in the upper 

 part, but ^^^th a conical or filiform appendage beyond the tuft. Recept. chaffy. L. opposite. 

 Gen. 439, 440. 



In the two following tribes the branches of the style are truncate, with a terminal tuft of 

 glands : — 



4. Anthemide^. Crest 0, or only a short crown. Gen. 441-449, 451-453. 



5. Senecionide^. Crest hair-like. Gen, 454^59. 



6. EupATORiACE^. " Style of the complete Fl. cylindiical. Branches long, somewhat club-

 often ceasing before the middle of the branches of the style." — DC. " Style of complete 

 Fit. cylindrical, cloven. Branches long, nearly terete or club-shaped ; upper part puberulo- 

 papillose." — Koch. Hecept. naked. Crest comiposed of hairs or bristles. Gen. 460^<65. 

 I adopt this tribe in compliance with two such distinguished botanists as De Candolle and 

 Koch, and for the sake of convenience, without understanding, exactly, in what its essential cha- 

 racter consists. It includes two groups, differing in habit from each other, and from all the 

 other tribes. There are no radiate Fits., except in Tussilago ; and the separation into those 

 which have, and those which have not, one or more series of fertile florets, is not a natural one.
