@Pushkraj, I have been trying to but am unable due to its size, location of the plant. Will keep trying. I have looked for it in flowers of India website with no success yet. I thought it could be a variety of Murraya, but I am not spotting any convincing evidence.
No @Pushkraj, no berries either. Interesting plant has just a few quite old branches (3-4), never has had any new branches in last 2 years. Old wood gets small twigs of leaves and buds around this time of the year. Very fragrant!
