582. (42.) Chrysanthemum Tournef. 
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 
hemispherical, 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 microscopical characters, having 
little relation to general habit. Among them Pyrethrum has been the most 
generally adopted, although botanists are but little agreed as to the characters 
or species which should be assigned to it.
