only one flower-head each. 
35. DORONICUM. 
Herbs with few cauline and simple radical leaves, and yellow 
flowers. Involucral bracts in two or three series, equal. Disk- 
florets perfect, ray female, destitute

May. ; 
2. D. Pardaliinches. Common 
Leopard’s Bane.—This is a com-

and its pale yellow flower-heads

36. SENECIO. 
This vast genus contains several | 
hundred species, but only one need Fig. 146, Doronicum Caucasicum, 
occupy our attention here. The ea 
chief chaiacter is the involucre of one row of equal bracts. 
Flower-heads often destitute of ray-florets, asin S. vulgaris, the 
common Groundsel; or rayed, as in 8. Jacob&a, the Ragwort. 
The name is derived from senez, an old man, in allusion to the 
abundant silvery pappus, or, as it is sometimes explained, the 
naked or bald receptacle. 
1. S. élegans.—This commonly bears the name of Jacobéa, 
which belongs to another species. It is a very familiar plant 
in gardens, especially the double purple variety. There are 
also white, flesh, rose, and crimson varieties, which will come 
true from seeds. South Africa,
