Naming and culture: Phalaenopsis vs. Doritaenopsis

[squarebear]

I just received my first two orchids on Thursday - both Phals (or so I thought). When I ordered them from the nursery, the website listed the name of one of them as Phalaenopsis Newberry Perfection 'Pink Giant,' but when I received the actual plant, the tag in it read Dtps. Newberry Perfection 'Pink Giant.' Google tells me Dtps. = Doritaenopsis, a cross between a Phal. and a Doritis. Interesting!

So 2 beginner questions, if you all would be so kind:

1. Would it be incorrect to refer to this plant as a Phal.? Or maybe a better question would be, is there a naming scheme here that would be considered "most correct" when listing the plant?

2. Are there any differences in the culture of Phalaenopsis vs. Doritaenopsis?

Thanks!
