Many thanks … for showing this <\/span>Ixora<\/i>. <\/span>Ixora<\/i> species are very confusing – especially those found in gardens.
\n<\/span>Hoping we get more and more uploads of garden Ixora for help in ID.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n

Yes …, i agree with you, Ixora sps R really confusing.<\/div>\n

\nSeems to be I.coccinea<\/i>. Can you confirm ?<\/div>\n
\n
\n

For me the ID is correct.<\/p>\n

\n

I think closer to Ixora casei<\/i> Hance<\/span><\/span><\/span><\/a>\u00a0rather than those of Ixora coccinea<\/i> L.<\/span><\/a><\/span>\u00a0as per keys and details herein.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<\/div>\n

\n
\n<\/div>\n
i believe that Ixora casei<\/i> is endemic of Carolines Islands. I.coccinea<\/i> has differents varieties, red, yellow, pink…<\/span><\/div>\n
\n
\n

I. casie<\/i> is also cultivated in India. You did not check the keys at the given page.
\nIt has larger leaves and leaves have petiole.<\/span><\/p>\n

\n

I thought it was not in India. OK for Ixora casei<\/i>.<\/span><\/p>\n

Please note<\/span>\u00a0leaf with short petiole, scarlet flowers with 25-35 cm long tube and acute corolla lobes.<\/span>\u00a0Please also consider<\/span>\u00a0I. casei<\/em>, a very close species.<\/span><\/p>\n<\/div>\n

\n
\n

I also think this plant is\u00a0Ixora fulgens<\/em>\u00a0Roxb because I used to have this plant in my terrace garden but later died.<\/p>\n

\n

If stipules are deciding factor, then my second photograph\u00a0clearly shows nearly 7-9 mm long interpetiolar stipule, triangular at base and narrowed above.<\/span><\/p>\n

\n

As far as my knowledge extends I know that these two species of\u00a0Ixora<\/em>\u00a0can be differentiated by prescence or abscence of stipules. As you plant has the stipules (stipulate) hence it is\u00a0Ixora fulgens<\/em>\u00a0. 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 .<\/span><\/p>\n

Ixora fulgens<\/em>\u00a0is a different plant with much narrower leaves<\/div>\n
Your comments please<\/a><\/div>\n<\/div>\n<\/div>\n
\n

Here is another evidence that our plant is not I. fulgens<\/em>\u00a0(syn:\u00a0I. salicifolia<\/em>):<\/a>

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.<\/span><\/p>\n<\/div>\n

\n
\n<\/div>\n
\n

Yes, thank you very much, \u2026 indeed very normal for the delicate anther to fall off during due course of pollination \/ or obvious lifecycle of the flower.<\/p>\n

\n
The matter seems to be still open.\u00a0The book tropical ornamentals: a guide by W. Arthur Whistler mentions presence of interpetiolar stipules in\u00a0I. casei<\/em>, whereas another site (I lost track) mentions stipules absent.\u00a0<\/span>I am not very sure about second, because we think about different length of stipules but not total absence.<\/div>\n
The main feature that goes in favour of\u00a0I. casei<\/em>\u00a0is the leaves being clearly elliptic-oblanceolate whereas they are lanceolate or linear-lanceolate<\/span>\u00a0(in\u00a0I. salicifolia<\/em>, regarded as direct synonym of\u00a0I. casei<\/em>\u00a0or\u00a0I. casei<\/em>\u00a0var.\u00a0salicifolia<\/em>).\u00a0<\/span>Also the leaves of\u00a0I. casei<\/em> are larger.
\n<\/span><\/p>\n
\n

Thank you for updating me about the literature. As Leaf morphology is the point of identification then you assumption can be right\u00a0!!<\/span><\/p>\n

\n

Today I found another Ixora in Herbal Garden that led me to rethink and confirm more strongly that this plant is indeed\u00a0I. casei<\/em>.\u00a0Ixora fulgens<\/em>, I found out has larger flowers with 15-17 mm long corolla lobes<\/span>,\u00a0whereas this one has 9-11 mm long lobes. This leads me think that this plant is\u00a0I. casei<\/em>.<\/span>\u00a0Please validate.<\/p>\n

\n

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\u00a0Ixora case<\/i>i.<\/span><\/span><\/p>\n

\n

How about\u00a0Ixora Chinensis<\/em>. Please check the link.
\nhttp:\/\/en.wikipedia.org\/wiki\/File:Ixora_chinensis_1.jpg<\/span><\/a><\/p>\n

\n

In\u00a0I. chinensis<\/em>\u00a0petals are obtuse at tip and leaves not with petioles.<\/span><\/p>\n

\n<\/div>\n<\/div>\n<\/div>\n
\n

please delete this entry and shift discussion under I. casei<\/em>, because same plant has already been posted separately as I. casei<\/em>.<\/p>\n

Interesting. Sorry to be awkward!<\/p>\n

Ixora casei<\/em> seems rather rare.<\/p>\n
I have never knowingly come across it.<\/div>\n
Is it found in India?<\/div>\n
Native distribution areas:<\/p>\n
\n

I have tried to search hard in the internet and books available with me.\u00a0There are lot of photographs of\u00a0I. casei<\/em>, but hardly any of\u00a0I. fulgens<\/em>. Finally I stumbled upon information that\u00a0I. salicifolia<\/em>\u00a0is a synonym of\u00a0I. fulgens<\/em>, that put me to doubt, because then it meant leaves would be linear-lanceolate like salix. This photograph confirmed my doubt
