bulbophyllum purpuraceum?

[DTB]

Hi all,

I bought this under the above name but can find no info about it or even if this plant exists and unfortunately the place I bought it are rather useless.
The flower has formed similar to Bulbophyllum purpurascens but is yellow instead of white. The leaves have a characteristic 'purple' line running down the centre.


Has any one heard of Bulbophyllum purpuraceum before?
Could this a cross of Bulbophyllum purpurascens and something else?

Sorry for the lo res image, it was taken on my phone.

Cheers
