Pl find the pictures of Canthium dicoccum and confirm the ID. Photo taken during 2011.
I think matches with images under various threads at Psydrax dicoccos, particularly the following:
Thanks … for updating the name.

Canthium of Rubiaceae?
I think it is Psydrax dicoccos Gaertn., var. dicoccos (Syn. Canthium didymum (Brandis) Hook.f., Plectronia didyma Benth. & Hook. f. ex Brandis, Canthium dicoccum (Gaertn.) Merr., )
Thanks … In fact I also narrowed it to the same species.

seems to be matching in general but the leaves width, does it seem a bit narrower in your specimen from what we have on this page?
Can anyone please explain specific differences between Psydrax dicoccos and P. umbellata?
Based on the above images, in the absence of fruit, my guess would have been P. umbellata, the species with which I am familiar.
Please, I think the main difference would be location, flowering time, shape and form
I pulled up 2 links.
thank you … I have seen the links you provided. Not at all sure about the plant photographed at Matheran in the second link. I am trying to get detailed botanical descriptions to answer my question.
Prashant ji’s images of Psydrax dicoccos in FOI, looks to be of Psydrax umbellatus, as per images and details herein and as flowers umbellate on a short very stout compressed peduncle as per IBIS Flora (Flora of British India) vis a vis cymes compressed shortly peduncled for Canthium didymum C.F.Gaertn. (syn. of Psydrax dicoccos var. dicoccos as per POWO) as per IBIS Flora (Flora of British India).
I think you are right. Prashant’s plant has flowers on a very short peduncle. It should be Psydrax umbellata.

I go for Psydrax dicoccos
Thank you very much for ID my plant.
My tree resembles to Psydrax dicoccos, but I couldn’t see these kind of inflorescence or flowers as per efloraofindia images, from my frequent visits. I also pointed that my tree bloomed only with full of this kind of tiny flower (single) on both opposite axillary in young as well as medium old branchlets.
Please zoom the attached images and see flower heads with all axillaries.
It reminds me of Psydrax as well.
Perhaps what we have here are not flowering bodies at all! Could these be small axillary spurs instead? Solitary, axillary projections like the ones in this photograph of Psydrax (syn. Canthium) on the Biotik website. Similar projections can be discerned in some photographs of Psydrax in the efloraofindia archive. I don’t know what the white substance in … images could be, maybe it is an infection.
I also found similar growth in the attached image of Canthium dicoccum from (https://efloraofindia.com/2011/08/24/psydrax-dicoccos/) from the thread: ANOCT79 Psydrax dicoccos (Canthium diccocum)
Yes dear …, but it is very short, flower head is different and having bract on branchlet (please check the resized EFI screenshot). My tree is full of this kind flower heads
Might be galls???
I don’t know what is in it, but I am sure they are flower heads
