Chrysanthemum rotundifolium is a very showy Hungarian 
Michaelmas Daisy, differing much from those in general 
cultivation by its strict rigid habit, acutely angled stem 
and branches, corymbose many-flowered inflorescence and 
broad leaves. In habit it belongs to the section Pyrethrwn 
(genus Pyrethrum of Geertner), which includes most of the 
perennial white-flowered species of Chrysanthemum, but it 
differs from that section as defined by modern authors, in 
the terete, not ribbed or angled achene, and in the cupular 
pappus, and it accords with no section as hitherto defined. 
C. rotundifolium is a native of the mountain valleys of 
Hungary, Transylvania, and Bucovina. It is rather a low- 
growing species, not exceeding two feet high in the Royal 
Marcu lst, 1892.
