Hi Sheeba! Well the flowers look pretty similar to Acampe rigida, but the lip on your flowers is white and the photo on IOSPE seem to be all yellow with the red or orange barring. I'm not an expert at this so hopefully someone else will jump in. Here is a link to the description of Acampe rigida:

An interesting note, if you check out the other names or synonyms for this plant on the link I provided you it is also know as Gastrochilius, Aerides, or Vanda...so maybe you might be able to find more information under a different name...I'll check OrchidWiz tonight and see what name it comes up under!
And to answer your question, I do believe it belongs in the vanda alliance.
