Vanilla-leaf - Achlys triphylla
Named for the scent of the dried leaves, this perennial is common and often locally abundant, carpeting the forest floor, reaching about 5000 feet on the trail to Owyhigh Lakes (although below 4000 feet in most places). Photographed (left and center) at Sunshine Point on May 18, 2014 and (right) along the Twin Firs trail on June 30, 2016.
