ID this purple yellow white & maroon orchid, possibly den.
 

Saw this at the NYBG last weekend, and I really want one.

If you know what it is, or where I can get one, I'd sure appreciate the info.

its a dendrobium nobile of some hybrid type

I would search online for Dendrobium nobile. I think Kawamoto orchids may have many...

just look for a similar hybrid

Yamamoto in Hawaii has been breeding these for decades here is a link.

ooops I confused Kawa for Yama!
