ETJPATORITJM (from an ancient personal name). 

 Comp6sita'. More than 400 species, mostly of warm or 

 tropical countries, herbs or shriihs. Heads discoid (ray- 

 less), the florets 3 to many, perfect: involucre cylindrical, 

 bell-shaped or hemispherical, the imbricated bracts in 

 2 or more series: receptacle flat or conical, naked : co- 

 rolla regular, 5-toothed, slender-tubed: akenes 5-angled, 

 truncate : pappus a single row of hair-like, scabrous 

 bristles : perennials. 



Gardeners know two classes of Eupatoriums, the glass- 

 house and the hardy kinds. The latter are native spe- 

 cies which only lately have been introduced to the trade 

 as border plants. The glasshouse species are seen only 

 in the larger or amateur collections, as a rule, althoxigh 

 some of them are old garden plants. They are confused 

 as to kinds. These species demand the genera! treat- 

 ment of Piqueria {or Stevia),— a cool or intermediate 

 temperature and pot culture. They are easy to grow. 

 Prop, readily by cuttings. They are useful for winter 

 bloom. Of all Eupatoriums the individual heads are 

 small, but they are aggregated into showy masses. For
