COMPOSITE FAMILY 



but Aster prenanthoides is easily distinguishable 

 by its abundant bloom, a glowing mass of pale 

 violet brightened by its yellow disks and dark- 

 ened by its purple ones. 



The shape of the leaves is a distinguishing 

 character, oblong or ovate-lanceolate, more or 

 less serrate, with winged petiole — which often 

 broaden at the base and clasp the stem. Both 

 leaves and petioles vary, but this is the typical 

 form. The bloom lasts late into autumn.
