What's in the mix? - Dendrobium x somethingii

[Trollsvans]

Got this from a friens a while back, finally got it to flower.
I know it's a Dendrobium, and I'm fairly certain it's a thirteen-a-dozen kind of hybrid, but I'll gladly take any hints on possible ingredients, or at least what section it ought to contain (to better match its requirements)

Pendant growth, seems to be deciduous or semi-deciduous, the cane gets to some 45cm/18", leaves are light green and rather thin (but that might just be me being too crap with waterings).

Looks like it has some Den. unicum in its parentage.

Ah, that'd explain its tendency to flower upside down... I just thought it was a bit crap-in-the-head, so to speak.

I'll have to check that one up...thanks!

[Trollsvans]

Any other ideas on possible parents?

Identified as one of the D. Stardust varieties.
Parentage includes nobile, unicum and three other species.
