Possibly Ixora fulgens from Delhi growing as hedge in Khalsa College Campus, Delhi. Please note leaf with short petiole, scarlet flowers with 25-35 cm long tube and acute corolla lobes. Please also consider I. casei, a very close species.

Dear Gurcharan ji,

I also think this plant is Ixora fulgens Roxb because I used to have this plant in my terrace garden but later died.

Regards

Tanay

If stipules are deciding factor, then my second photograph clearly shows nearly 7-9 mm long interpetiolar stipule, triangular at base and narrowed above.

Dear Sir ,

As far as my knowledge extends I know that these two species of Ixora can be differentiated by prescence or abscence of stipules. As you plant has the stipules (stipulate) hence it is Ixora fulgens . I will still request you to check about this stipule character from the floras as you have lots of them with you, it will be very easy for you to recheck the morphology from the literatures. Kindly let me know wether I am right or wrong .

Regards

Tanay

I have tried to search hard in the internet and books available with me. There are lot of photographs of I. casei, but hardly any of I. fulgens. Finally I stumbled upon information that I. salicifolia is a synonym of I. fulgens, that put me to doubt, because then it meant leaves would be linear-lanceolate like salix. This photograph confirmed my doubt

http://www.meemelink.com/prints%20pages/13766.Rubiaceae%20-%20Ixora%20fulgens.htm

I think that my plant (and that uploaded yesterday by Dinesh ji, and which we have been considering as I fulgens) is I. casei and not I fulgens:

Ixora fulgens is a different plant with much narrower leaves

Your comments please

Please have look at my third photograph. In midle flower under focus all anthers are fallen. Lowermost has one anther only, similar to your photograph.

Yes, thank you very much, Gurcharan ji ... indeed very normal for the delicate anther to fall off during due course of pollination / or obvious lifecycle of the flower.

Dear Gurcharan ji,
Did you check about the stipule matter !! As far as I know I casei doesn't not have stipules but all the pictures showed the presence of stipules.

Tanay

Dear Tanay

The matter seems to be still open. The book tropical ornamentals: a guide by W. Arthur Whistler mentions presence of interpetiolar stipules in I. casei, whereas another site (I lost track) mentions stipules absent. I am not very sure about second, because we think about different length of stipules but not total absence.

The main feature that goes in favour of I. casei is the leaves being clearly elliptic-oblanceolate whereas they are lanceolate or linear-lanceolate (in I. salicifolia, regarded as direct synonym of I. casei or I. casei var. salicifolia). Also the leaves of I. casei are larger.

Dear Gurcharan Ji,
Thank you for updating me about the literature. As Leaf morphology is the point of identification then you assumption can be right !!

Today I found another Ixora in Herbal Garden that led me to rethink and confirm more strongly that this plant is indeed I. casei. Ixora fulgens, I found out has larger flowers with 15-17 mm long corolla lobes, whereas this one has 9-11 mm long lobes. This leads me think that this plant is I. casei. Please validate.

Dear Gurcharan Ji,
Its bit for me to get hold of the fine measurements from the photo !!! I think your assumption can be true !! And hopefully this is Ixora casei.

In I. chinensis petals are acute at tip and leaves not with petioles.
