Both the person I got this from and a few others are not sure of the name. There is a discussion going on now with an orchid club in Ontario. Some think it is a different species, some think it is not an alba because of the dark coloring and some want to wait until they have a chance to examine this more, so for now I an going with the name on the tag. I got this in July and it has another spike still growing.
