Dendrobium williamsonii ?

Dendrobium williamsonii Day & Rchb.f., Gard. Chron. 1869: 78 1869. (Syn: Callista williamsonii (Day & Rchb.f.) Kuntze?

One more Orchid for id from Manipur
These printed Pics were shot and provided to us by some of ours Classmates from Manipur ( Who were resident of Manipur) in 1998.
I need to see the spur. This is strange. I didn't know it was found in India.
Looks very close to Dendrobium williamsonii.
Thanks ... These were shot from Manipur or may be from any near Northeast state of India. This was the only picture available with me
