Small number of leek orchids growing in sub-alpine bog at this location (about 15 in total still flowering) with a lot of variation in flowers. This darker flower was the biggest variation in both colour and flower shape. I could only find one of these plants growing in the middle of the lighter forms.
I've posted the main variations here as separate sightings (with the abundance number on each sighting reflecting the number of the particular variation). I've only gone with P. sphacelatum (on all of them) as there was no Prasophyllum sp in the list to choose ;) All of the plants in flower had no leaves or withered leaves - so I thought P. sphacelatum rather than P. tadgellianum. Other option might be P. canaliculatum I guess - as location is similar. Interested to see what the experts think! Glen
