Spotted Coralroot (Corallorhiza maculata var. maculata)

There are two varieties of this leafless, saprophytic orchid - in the variety shown the sides of the lip are parallel while in the Western Spotted Coralroot (var. occidentalis) they are rounded, giving a much fuller appearance to the lip).

These two varieties often grow together, but bloom at slightly different times.
This plant was photographed on the grounds of the Au Sable Institute in Coupeville, Washington.
