Ploidy and crossings What do you get?

[Ryan Young]

So i came across a book Breeding Dendrobium Orchids in Hawaii giving the ploidy cross experiment in a table.
(# in parentheses =# examined)

2n x 2n (45) 43/ 2n, 2/ 3n
4n x 4n (25) 25/ 4n
2n x 4n (37) 37/ 3n
4n x 2n (99) 99/ 3n
3n selfed (16) 1/ 3n, 2/ 3.5n, 13/ 4.5n
2n x 3n (40) 2/ 2.5n, 38/ 4n
3n x 2n (96) 96/ 4n
4n x 3n (13) 9/ 3.5n, 4/ 5n
3n x 4n (127) 111/ 3.5n, 16/ 5n

So my question is what would be the ploidy crossing say 5n with 2n 3n or 4n?
