Jasminum nobile C. B. Clarke subsp. rex (Dunn) P. S. Green, Kew Bull. 50:577. 1995 (Syn: (≡) Jasminum rex Dunn (basionym)) as per GRIN ; 

Cambodia; Laos; Myanmar; Thailand as per Catalogue of Life;
This creeper was taken at a resort in Kandy, Sri Lanka on the 17th of November, 2010. The size of the flowers was the biggest I have seen in Jasmines.

Perhaps Jasminum sambac (L.) Aiton

Jasminum most likely but not sambac!

Jasminum nervosum..thats what i think

Jasminum rex

Jasminum rex Dunn. is a synonym of Jasminum nobile CB Clarke

– I think this is Royal jasmine (Jasminum rex) which has pink buds, and large flowers which have overlapping petals, native to Thailand.    

Jasminum rex Dunn is an accepted name. Jasminum nobile subsp. rex is its synonym.

This most likely to be Jasminum nervosum Lour. More info is available in http://www.efloras.org/florataxon.aspx?flora_id=3&taxon_id=200017785

Next close one could be Jasminum subtriplinerve Blume.

It could be Jasminum sambac.
