Blooming period from about June 14 throughout the season 

 until destroyed by heavy frosts. Flowers were found as late as 

 November 5. Kirchner 30 has observed this species in Germany. 

 The white rays are very numerous (about 100 according to Kirch- 

 ner), and gradually assume a horizontal position. 



In the bright yellow discal florets the upper widened portion 

 of the corolla measures J / 2 mm. across, and 1 mm. in depth. The 

 corollar lobes are short and slightly spreading.
