…, it looks more like Psychotria dalzellii Hook.f.
Coriaceous leaves and white infruitescence – both are clear in your pic.

efi page on Psychotria dalzellii

In P. dalzellii the peduncle bright white and elongated, sub succulent, leaves are with more number of thin nerves. that is the reason for my decision, I have uploaded Psychotria dalzellii also.

Please post more images. Flower close up, full leaf, stem, habitat.

Psychotria, resemble P dalzellii

But it is a tree…

Tried in Myrtaceae, but failed.

Its a species of Psychotria

Do we have small trees in Psychotria?

Yes, P. anamalayana is a small tree. There may be other species growing to the size of a small tree.

May I request you to post habitat images etc. for further determination.

I checked all the species listed in flora of Peninsula India in POWO and GBIF, with distribution given in the district.
The closest I can go is Psychotria nilgiriensis var. astephana as per GBIF specimen. Alos see POWO.

Biotik says it to be ‘Large shrubs or small trees ca. 4 m tall’

This is Psychotria subintegra

Thanks, … These two GBIF specimens look closer- one and two
