it is Dimorphocalyx species

Yes, appears close as per images at

Yes, it is , thank you very much for ID my plant and providing ID link,

It appears to be Dimorphocalyx glabellus var. lawianus (Hook.f.) Chakrab. & N.P.Balakr., as per keys in BSI Flora of India.

it is not D.glabellus, the leaves have impressed veins, not found in glabellus; the ovary is very hispid; the calyx lobes shape is also different; it must be some other species,

This is what BSI Flora of India says:

Leaves elliptic, oblong to obovate or oblanceolate, rounded, obtuse to acute at base, shallowly glandular-crenulate (particularly in young leaves), crenate-serrate to entire along margins, acuminate to acute or often obtuse to rounded at apex, 4.5 – 19 x 2 – 7 cm, thinly coriaceous to chartaceous; lateral nerves 6 – 14 pairs; petioles 2 – 20 mm long.

The identification is correct. Accepted name: Tritaxis glabella (Thwaites) R.Y.Yu & Welzen var. praerervisa Chakrab. & G.Krishna.

Great identifying!!
Yes, it is, thank you very much for ID my plant,
