CONEFLOWER 



RAYLESS CONEFLOWER 



Coneflower (Rudbeckia). The yellow coneflower, 

 or golden glow, is not abundant in the Park, but is 

 found to a certain extent in moist, open places at the 

 lower elevations. It is very variable in height, averag- 

 ing perhaps three feet. The stem is stout and smooth, 

 with several long branches. In addition to the stem 

 leaves, there is usually also a considerable mass of 

 leaves at the base ; they are fairly long stemmed, broad 

 at the outer end, and are deeply cleft into three or five 

 divisions. The blossom resembles a small sunflower, 

 except that its disk is elevated into a long, blunt-ended 

 cone. 



Rayless Coneflower (Rudbeckia) . This plant, one 

 of the most curious and striking in the Park, is blood- 

 brother to the yellow coneflower, but resembles it very 

 little in general appearance. Its height is about the 

 same or a little less, but the stem is hairy and rough, 

 and the leaves are broad at the base, uncleft, and come 

 to a sharp point. They also are very rough. Of the 

 flower there is nothing but the black, conical disk ; the 

 rays are entirely lacking. The cone is large, about 

 an inch in diameter and one and one-half inches long. 

 It appears in late July and lasts through August.
