Corallorhiza trifida had been seen just coming into flower a few days before this photo was taken and so, with a GPS and a ten figure grid reference we should have walked straight to it. We did walk to it actually but it is so difficult to see in its habitat that it took ten minutes or so before any were spotted.

It is saprophytic or more precisely mycoheterotrophic which means it feeds of the the microrhizal fungi which surround the root system of this plant (and many other orchids too). It does produce a limited amount of chlorophyll so some plants appear greenish. This one and other plants around it had no green coloration at all but it could well appear when setting seed.

The root shape is said to resemble coral which gives the plant its name. It has a strictly Northern distribution and Yorkshire is its most southerly outpost. It does not occur in Ireland.
