Antennaria pulcherrima
 
Showy Everlasting

Male Floret

14 Miles North of Hudson Bay on Highway # 9
10-July-2019

Note the pappus bristles of male florets are dilated at the apex.  The stamens are connate with the inner surface of the corolla tube and the anthers form another tube around the style.  The anthers dehisce introrsely with the pollen pushed out of the anther tube by the growth of the style.  The styles of male florets are sterile and unbranched.
