It definitely has the look of an Aranda with the Arachnis 2 or 3 generations back, and the appearance is believable for Aranda Woleco, but almost any hybrid that combines mostly Vanda coerulea and Vanda sanderiana with some Arachnis could look much like this. If there is a label that says Aranda Woleco I would believe it, but unless there is some other reason than "it looks like" to think it is Woleco you just can't be sure.
