Nice gift! It looks a lot like the one I have labeled G. espiritensis var baiana but I wouldn't go by my impression. From what I've read, G. espiritensis, araceana, and liboniana are pretty closely related and on top of that, there's supposed to be a fair amount of variability within the species. There are a few photos on the PBSWiki site, as well as photos and an identification key on Kevin Preuss's website, if that helps.

My G. espiritensis made fertile seed again this past fall, although it's supposed to be self-incompatible. I've got one seedling with leaves and a second germinating.

Meant aracensis there, not araceana. Not sure what dark recess of my spelling brain that came out of.

It looks like my espiritensis as well and given that this is likely the most common species that is what I would assume, but I agree with karen....they all look about the same, with obvious exceptions. I received a nice size aracensis from a botanical garden so I hope it blooms this summer so I can compare it to my Kevin Preuss Identified espiritensis. The one variant I have 'alba estrelada' blooms almost 9 months out of the year so it is a real favorite.

Great pic regardless of the exact species....a beauty :o) Dan
