Based on Todd Boland's descriprion and experiments documented in Dave's Garden

It would appear that Murrayana is a virginica. Flowers are below leaves. when crossed with versicolor showed typical "Robusta" characteristics and was sterile.
It was discovered in a protected evironment on a river bank in an apparently shaded area. If this area was revisited there would likely be found some isolated patches of virginica. Even more likely in consideration that there are virginica plants on Gaspe Peninsula ( where Anderson collected his data set, that Fisher analyzed). This is a short distance from Newfoundland. Of interest is that in terms of virginica, it is described as only being located in Point Pele in Canada. Yet Anderson found it in Gaspe Peninsula. So I'm betting on Anderson. I'm also betting that it could very well be found in Newfoundland, in some of the interior regions. Just not been properly identified, probably not being distinguished from versicolor.
Some robustas are sterile, some are very fertile.
As Murrayana doesn't have purple based foliage, it wouldd appear that flowers are white as plant is an albino. That is, it doesn't produce any anthrocyanin anywhere in plant. This is different than when plant can produce anthrocyanin but shuts it off for flower.
Of further note. I collected a very nice clone of versicolor from Newfoundland some years ago. Has beautiful flowers and has close to 10 flowers on a stalk.
