Please help for identification
 

Here I attach 3 photos of a dendrobium species of North east India. Actually I was collected that plant as a Den. pierardii because the plant are mostly same to pierardii. But after bloom i saw the lip is not same to den pierardii. I had never seen this den sp in any book which I saw or internet.
Please help me to identify or guide me where I send the photographs for identification.

what is the size of the flower?

something similar to D. gonzalesi

Thanks for your response.
The size of the flower is almost like Den. pierardii. it's 6-8cm.
But I think this is quite different to D. gonzalesii.
1) Leaves are not same.
2) Pseudobulbs are not same.
3) Labellums shape like similar but the texture in the labellum is deferent.
4) I noticed the gonzalesii blooms in cluster but this den bloom one or two from each node.
So sorry, I am confused.
