A quick web search for Phal. Silibama turns up that the plants name is P. Silibama. I can't help with the number after it, it probably is an order number or number given to identify the plant in a data base somewhere.
P. Silibama still looks like it must have some species Phal. amabilis in it.......that would also explain the name......
There is a picture of it at this address:

LITTlEFROG: You are probably right about the clonal name for Baldan's Kaleidoscope, they have been mericloned to death. LOL
I'm 99% sure about the harlequin. P. Ever Spring Fairy 'Shan Pin'. It was printed on the pot and I really did spend hours verifing it.....
