More Coralroots

We visited recently a site on Whidbey Island where we had seen the Western Coralroot, Corallorhiza mertensiana, many times before, but we did not find very many of them this year, though enough to photograph.  These showed the usual rainbow of colors with pink, purple, white, tan and yellow stems and endless variation in the spotting of the flowers and coloring of the lip.

The endless variation in the color of this species makes it rather pointless to name different forms, but the light-stemmed forms have been named and are identified as Corallorhiza mertensiana fma. pallida.  We found plenty of these mixed in with the darker-stemmed forms, different color forms often growing in the same clump of plants, and all on rather barren forest floors.

It is interesting that in the mountains the native orchids seem more abundant this year, but near the coast the orchids have been fare fewer.  Perhaps in both cases this is due to the warm winter and early spring.  A friend has suggested that at higher elevations the warmer temperatures have encouraged the growth of the mycorhizal fungus associated with these orchids.

At the same site we found a few stems of the Ozette Coralroot, Corallorhiza maculata var. ozettensis, an unspotted form and a recent discovery.  We had seen it at other sites on Whidbey Island but this was the first time we found it growing with the Western Coralroots.  We'll be visiting another site in the near future to photograph it there, a site where it grows in abundance.

Ninth Orchid of the Season and Another First

On one of our recent hikes we found and photographed Cypripedium montanum, the Mountain Lady's Slipper, our tenth orchid of the season.  We saw hundreds of them at two different locations, most of them either the very dark form with the burgundy-edged pouch, forma welchii, of the paler greenish form.  Among them we found two plants with three flowers of the albino form, forma praetertincum.  We had searched for this form before and never found it, except for one tiny crippled flower a year ago that we did not even photograph.  These flowers were in prime condition, and though the light was failing in the evening, we managed to get decent photos.
