very Beautiful … Never seen this colour in Ixora.


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


Thanks … for the correct ID

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).

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’.

Nice photograph!!  The Southern Birdwing [Troides minos] female is the largest among Indian butterflies.


may I know the food plant of this butterfly?


Some species of Aristolochia [A.indica, A.tagala] are the foodplants of this butterfly.


I think it may be Ixora chinensis Lam. as per keys and comparative images at Ixora

red & reddish yellow Ixora sp.:
Found this Ixora sp. in The Agri-Horticultural Society of India, today. This plant is a bit smaller than my previous post, “giant Ixora sp“, and the corolla segments here are ovate. Could it be Ixora chinensis Lam.?

Species : Ixora chinensis Lam. ?
Habit & Habitat : shrub, about 6 feet, garden
Date : 25-05-12, 12.50 p.m.
Place : The Agri-Horticultural Society of India, Alipore, Calcutta (Kolkata)
ID Help :

2) http://www.jaycjayc.com/ixora-species-jungleflame/
Please, note that the images were taken from two different individuals, but one both the plants were bearing red & reddish yellow flowers.

i think determination to species level of certain Ixora sp. should be done only after physical examination by experts. Some info on identification of Ixora, using genetic markers, can be found at – aob.oxfordjournals.org/content/80/3/355.full.pdf, also attaching the file for future use in the group.
