Ixora casei (Cultivated)

 
Shrub or small tree up to 3 m tall; leaves opposite, lanceolate to ellptic, glossy, 10-25 cm long, apex acute or acuminate, petiolate, petiole up 5-15 mm long; flowers tetramerous, in corymbose usually trichotomously branched cymes; calyx lobes rudimentry; corolla tube slender, 3-4 cm long, lobes 4, 12-15 mm long, red (in culivar Super King, yellow or orange in wild plants in native place), spreading, tip acute to acuminate. 
 
The species looks similar to I. coccinia with similar coloured flowers, as long corolla tube and and acute corolla lobes, but can be easily differentiated on the basis of longer narrowly elliptic leaves reaching 20 cm in length, leaves gradually narrowed towards base and with distinct up 4-7 mm long petiole, and narrower much more pointed corolla lobes.

Ixora coccinea is characterized by sessile leaves with rounded leaves. This one clearly has leaves narrowed at base, with a short petiole. THis should be Ixora casei

Many thanks ... for showing this Ixora. Ixora species are very confusing - especially those found in gardens.
Hoping we get more and more uploads of garden Ixora for help in ID.

Leaf patern indicates to Ixora coccinea.

again in Periyar, Kerala (900m), january 2019.
Seems to be I.coccinea. Can you confirm ?

For me the ID is correct.
I think closer to Ixora casei Hance rather than those of Ixora coccinea L. as per keys and details herein. 

i believe that Ixora casei is endemic of Carolines Islands. I.coccinea has differents varieties, red, yellow, pink...

I. casie is also cultivated in India. You did not check the keys at the given page. 
It has larger leaves and leaves have petiole. 
I thought it was not in India. OK for Ixora casei.
