A Dendrobium, but what type ?

[Davesp310]

This one has just bloomed for me. The plant itself looks a little like a small D.Speciosum (not that it is a specosum, just that the plant looks very like some smaller speciosum plants I have) - the tallest canes are around 6 inches tall and maybe 3/4" thick, it has 4-5 fairly thick and stiff leaves on each cane, and has just the one flower spike that emanates from between leaves on one side. Its a short spike with 6 flowers each around an inch across, yellow to pale orange with a brownish to purpleish spot in the centre.

I've been looking through a few books and can't really find anything that looks like this one ?

The pot in the pic is 5"

Any suggestions would be appreciated
