very Beautiful ... Never seen this colour in Ixora.

Not Ixora coccinea ..., which has sessile leaves and acute corolla lobes. This should be I. chinensis

Ixora coccinea L. ??
Yes, it is.
Looks like more than one species. Leaf base stem clasping nearly sessile, petals with pointed tip is true I . coccinea.

All from one place.
May be Ixora chinensis Lam. (Cultivated)- Ixora chinensis looks similar to I. coccinea in smaller flowers but obtuse (and not acute) corolla lobes and leaves subsessile (and not sessile).

For Species id please.

May be some Ixora chinensis Lam. cultivar-  Ixora chinensis looks similar to I. coccinea in smaller flowers but obtuse (and not acute) corolla lobes and leaves subsessile (and not sessile)
This looks close to Ixora chinensis 'Prince of Orange'.
