the 8th and 9th Sections of Jussieu's Corymlnfer&, the 

 other seven being marked by a naked or scaly Recep- 

 tacle, winged or naked Seeds, and tiosculous or radiated 

 Flowers. The last character is not always well de- 

 fined, nor free from variation. The change of flos- 

 culous, or regular, Florets, into ligulate, or radiant, 

 or tubular and neuter, ones, is, in this tribe, analogous 

 to the change of Stamens or Pistils into Petals, in the 

 generality of double Flowers. Examples of these 

 seven Sections are 



Sect. 1. Receptacle naked. Seed with down, or 

 crown. Flowers flosculous, Kuhnia, referred by Lin- 

 naeus to his Pentandria Monogynia, because of the 

 separate Anthers ; Cacalia, Eupatorium, Xeranthe- 

 mum, Gnaphalium, Fttego, and several others. Mn- 

 tisia and Barnadesia, being evidently radiant, seem 

 misplaced here. In Gnaphalium indeed the marginal 

 Florets are more or less ligulate, though too minute 

 to form a visible Radius. Seriphiwn, whose Calyx is 

 single-flowered, is well brought hither from the now 

 abolished Linnaean Order, Syngenesia Monogamia, 

 and Stoebe from Syng. Polyg.-segregata. 



Sect. 2. Recept. and seed as above. Flowers ra- 

 diant. Erigeron, Aster, Imda, fig. 66-69, Tussilago, 

 (whose Radius is very minute,) Senecio, Tagetes, Do- 

 romcum, &c. 



Sect. 3. Recept. and Seed naked. Fl. radiant. Ca- 

 lendula, Chrysanthemum, Matricaria, Be/ Us, c. 



Sect, 4. Recept. and Seed naked. Fl. flosculous.
