There is a Dendrobium Salaya Brown registered, but not just a Salaya.
Salaya Brown = Den. Bobby Mesina x Den. Da.
Both those parents are hybrids whose own parents are hybrids, so it looks like it could be quite a complex one with lots of species in.
I don't have time just now to trace it all back, but I use this site to trace them back when I want to. On the 'Grex Name Search' you enter the genus and the name and it finds the parents. You then repeat until you get back to species (lower-case first letter for species).
