Finally Platanthera obtusta in Washington


Platanthera obtusata, the Blunt-leaved Rein Orchis, is very common in the Canadian Rockies and further north and we've seen it often, so often that we do not usually stop to photograph it.  It was, however, one of only two orchids native to Washington that we had not seen in the state.


We'd been given several sets of GPS coordinates by a friend and finally found the species in the Okanogan Highlands in north-central Washington in two locations.  We had to do some scrambling and bushwacking to see it, but found it at peak of bloom and were delighted to add it to our list.


In both cases it was growing on the edge of a bog, about twenty plants at each location.  We did not stay long for photos since the mosquitoes were thick and biting, but got enough photos to record the find, beautiful in the photos but in fact rather small and uninspiring and easily missed.

New Location for Epipactis gigantea


Having information from a friend who found the species there (he was along on the excursion) we visited Dry Falls State Park in central Washington to see Epipactis gigantea, the Stream Ochid.  Reputed to be rare in the state there were thousands of plants at two locations in the park, and though the flowers were just beginning to open we were able to get enough photos to prove that we had seen the species there.

 



Epipactis gigantea is an attractive species, always growing near water and often on the very edge of streams and lakes.  That was the case here also.  Sometimes the flowers are rather dull-colored but often they are the opposite, as the photos demonstrate.  It is also a rather large plant as native orchids go, and it is surprising that with its size and the number of plants it had not been previously reported from this location.
