What an amazing flower show.
Very beautiful!
It somewhat resembles Psilanthus wightianus, may be a cultivar. Please follow and record leaf and fruit characters.
Wonderful  photograph of a  very beautiful plant. I could not see this  charming plant during my tenure in Chennai though I used to hunt for plants. Thanks for posting the photographs. Regarding the ID can you  please post the photographs of the foliage, if you have. Also intimate me the location of the plant in Chennai, so that I can visit  the place and have a look at this  beautiful shrub when I visit Chennai in the coming days.
I thank ... for forwarding the same for ID.  
Its a stunning plant.  Seems to be an Apocynaceae member. If large climber can check against Trachelospermum jasminoides, False Jasmine. Some info on the habit of the plant and leaves would be useful.
It is Coffea wightiana Wall. ex Wight & Arn (= Psilanthus wightianus (Wall. ex Wight & Arn.) J.-F.Leroy), after summer rain it will bloom completely. I used to see this from past 2 decades around Chennai

Found in Vandalur reserve forests.
Shrub.

May be Canthium angustifolium Roxb.
It can't be Canthium angustifolium. The fruits are in kind of double. But, mine is a single pulpy fruit.

jasmine for identification.
this was seen growing in Chinnar WLS, Idukki district in Kerala.
Chinnar is in the rain shadow area of the Nilgiris and the vegetation in the forest is deciduous in nature

Pl. check comparative images at 

thank you for the suggestion. i did check but did not find a clear match. perhaps i need to check again 

I could not find a match as per comparative images at Jasminum

Is it not some Rubiaceae

This may be a Rubiaceae member, never be a Jasminum sp.

It is probably Catunaregam so or may be Randia

Yes it is Catunaregam spinosa

I think it has lots of similarity to Catunaregam sp. or Randia sp.

May be Psilanthus bengalensis...

To me looks different from images at Catunaregam spinosa

To me looks different from images at Coffea benghalensis

I agree with ... I did check earlier but life too over and i forgot to write about it

It is Psilanthus wightianus of Rubiaceae, it is endemic to Peninsular India.

some more information.
It is Coffea wightiana Wall. ex Wight & Arn (= Psilanthus wightianus (Wall. ex Wight & Arn.) J.-F.Leroy), after summer rain it will bloom completely. I used to see this from past 2 decades around Chennai.
