Opposite leaves as one of the character of the family is depicted by … in the given pictures.
I am not sure how prominent the interpetiolar stipule is in this species!

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.

Please identify this plant. Photographed in Adyar Poonga, Chennai during 2011.

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

of flowers.
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.


Canthium?: 2 images.
Taken in the month of Feb in Talakona forests on the way to the waterfalls.

Canthium dicoccum


Psydrax dicoccos in FOI:

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).
Pl. correct.

I think you are right. Prashant’s plant has flowers on a very short peduncle. It should be Psydrax umbellata.
