This photo was taken in June at Goldstream Provincial Park, Victoria, BC. I am assuming it's a striped coralroot, it just has very thin sepals/petals. Maybe it had only recently opened? Any ideas?
Check Corallorhiza mertensiana instead. In my experience, it tends to have this flower morphology. If you dig a bit deeper into researching Corallorhiza, you'll also find that there's a fair bit of variability, such that some folks will recognize a number of varieties that don't seem to have gained widespread acceptance (yet?).
That looks more like it! It's very interesting you mention some people will recognise more varieties than others, as it seems my field guide (Plants of Coastal British Columbia, Revised) still places C. mertensiana as a subspecies of C. maculata and places a confusingly great deal of emphasis on the spotted lip. I will be keeping an eye out for further variability within these species during the spring.
