The pulsatilla is certainly vulgaris...albana is indeed yellow...I have that one and its a charmer. The gentian may well be angustifolia. There is much confusion in the trade between angustifolia and acaulis. Not easy to tell them apart. We have one at the Botanical garden labelled acaulis but I was able to ID it correctly as angustifolia 'Frei'. I guess it really doesn't matter. View it as a lovely spring-flowering gentian.
