406 SYNGENESIA— POLYG.-SUPERF. Artemisia. 



Common Cal. roundish, imbricated ; scales rounded, convex, 

 compact, membranous at the edges. Cor. compound ; 

 Jlorets of the disJc numerous, perfect, tubular, their limb 

 5-cleft ; those of the ciramifereiice few, with or without a 

 small, tubular, tongue-shaped, undivided petal, but no 

 stamens. Filam. m the florets of the disk only, very 

 short. Anth. in a 5-toothed tube. Germ, in all the flo- 

 rets small, obovate. Style prominent, deeply divided. 

 Stigmas cloven or notched, recurved. Seed-vessel none, 

 except the scarcely altered calyx. Seed obovate, naked. 

 llecept. rather convex, either naked or hairy. 



A numerous genus, herbaceous or shrubby, bitter, or in 

 some degree aromatic, almost without exception peren- 

 nial. Leaves alternate, more or less divided, or pinnati- 

 fid. Fl. in panicled clusters or tufts, small, not showy. 

 Herbage often hoary, or silky. 



No genus can be more natural, in spite of the differences 

 of the receptacle, which in some species is smooth, in 

 others hairy, affording an example of aberration in that 

 part, which is not accompanied by any natural or charac- 

 teristic distinction in any other. Linnanis, Jussieu, De- 

 Candolle, and most leading botanists besides, have there- 

 fore happily preserved this genus entire.
