Rubiaceae member- Kerala

 
396 ID wild tree: 23 high res. images.
Please ID wild rare tree. I observed that it’s bark will get attack (or consuming) from Sus scrofa (?) frequently (image#4425).

… identified it as Nostolachma crassifolia of Rubiaceae

I have doubts of this being Nostolachma crassifolia as per description in IBP and POWO specimen, as the inflorescence is not in subsessile axillary cymes.
I could not find any match as per comparative images at

I am trying but not getting anywhere.

Sharing fruit images of the same tree from the same location.

Fruit: drupe green into brown globular diameter: 04mm

Seed: brown single globular

diameter: 02.5mm.

Shared images of the the buttressed tree are of another tree.  Hence from 3rd image of 4th post to image of 9th post are of another tree, except 2nd image of 8th post.
4 high res. images.

Canthium dicoccum?

No matching.

Discospermum sphaerocarpum Dalzell ex Hook.f.

Thank you very much for the ID suggestion of my plant.

My ID request 580 was identified as Discospermum sphaerocarpum, and its flowers which are borne densely clustering in the scars of the fallen leaves. And fruit having multiple compressed curved circular seeds inside. But in ID#396 flowers are axillary and only one flower bud in opposite sides. The fruit is micro sized than D. spaerocarpum and I don’t know it’s diameter increases after days, but I am sure only globular single seed.

So, could it be Discospermum apiocarpum Dalzell ex Hook.f. ??

---

Yes, it is, thank you very much dear … for the identification of my tree.  The flower is very close to the image in the link provided.
