PURPLE CONE FLOWER 



Receptacle. — Oblong and in fruit cylindrical; chaff yellow-tipped. 

 Pappus. — None or a minute crown-like border. 

 A kenes. — Four-angled. 



Rudbeckia laciniata is one of the tall vigorous composites which 

 brighten the tangle and adorn the roadsides in August. It often 

 stands seven feet high, bearing a loose collection of long peduncled 

 heads, with disks somewhat elongated. The bright-yellow rays 

 droop a little, but the general effect of the flower-head is that of a 

 sunflower. 



The garden favorite, Golden Glow, is a full double form of Rud- 

 beckia laciniata which has been cultivated since 1896; but whence 

 it came or how it was developed seems to be quite unknown. It 

 was "found" among a collection of plants.
