Vanda denisoniana hybrid?
 

It sure does look like this one is a hybrid. What do you think? I am watching how high it would go.

I don't know if it's a hybrid or not - but love the yellow blooms!

The plant- especialy the leaves- is exactly looking like the plants that I have in my collection and from what I can see of the flowers it matches with the typical V. denisoniana : side lobes, lip, general shape but I have never seen a V. denisoniana with so bright yellow. Ask if flowers are fragant and if yes at what time of the day. It should be during evening and morning only in case of a real specie plant.
