Another Orchid-hunting Trip

 

I went on a two-day orchid hunting trip and visited nine different locations.  I found orchids at all but two of the locations and it was very late in the season for the orchid I expected to find there.  These are the results of that two-day search for our native orchids.

At the first location I found the Eastern Fairy Slipper and its natural hybrid with the Western Fairy Slipper, Kostiuk's Hybrid Fairy Slipper.  The Fairy Slippers were very sparse this year and the area they were in had suffered from a windstorm that left numerous blowdowns and blocked trails.

At the second location that had orchids I checked on a mixed population of Lady's Slippers.  There are that resemble the Mountain Lady's Slipper, flowers that resemble the  Northern Yellow Lady's Slipper and flowers that are clearly hybrids of the two in that population.

At the third location I found the Mountain Lady's Slipper and the Spotted Coralroot.  The Spotted Coralroots were all the round-lipped variety, but included numerous yellow-stemmed plants.  This usually rare form is more numerous than the normal form in this location.

At a fourth location there was another orchid I looked for but didn't find.  I did find more Western Spotted Coralroot, though far fewer than previous years.  The weather has been unusual and the Coralroots especially seem to have been affected, with fewer plants everywhere.

At a fifth location with orchids I found a few Mountain Lady's Slippers.  I also looked for Coralroots there and found none and for a small rare Lady's Slipper but did not find it, either.  The Mountain Lady's Slippers were at the peak of their bloom at this lower elevation, not the case higher up.

The other locations were also place where I looked for the Mountain Lady's Slipper and found it, though at the higher elevations they were just starting to bloom.  I also found plants of the albino form, green and white instead of mahogany and white.  They were not fully open, however.
