IX. CHRYSANTHEMUM. CHRYSANTHEMUM. 



Annual or perennial herbs (or in some exotic species, shrubs), with 

 alternate toothed or variously dissected leaves, and radiating flower- 

 heads, solitary on terminal peduncles, or in corymbs. Involucres he- 

 mispherical, with a few rows of imbricate bracts, more or less scarious 

 on the edges. Receptacle flat or convex, without scales. Achenes 

 angular or striate, without any pappus, but sometimes crowned with a 

 minute raised border. Style nearly that of Senecio. 



A considerable genus, extending over Europe, northern and central 

 Asia, and northern Africa. It has been divided by modern botanists 

 into a number of small genera, founded upon minute, almost micro- 

 scopical, characters, having little relation to general habit. Among 

 them Pyrethrwm has been the most generally adopted, although bo- 

 tanists are but little agreed as to the characters or species which should 

 be assigned to it.
