Ixora casei Hance, Ann. Bot. Syst. 2: 754 1852. (Syn: Ixora carolinensis Hosok.; Ixora carolinensis var. chartacea Fosberg; Ixora carolinensis var. volkensii (Hosok.) Fosberg; Ixora confertiflora Valeton [Illegitimate]; Ixora duffii T.Moore; Ixora pulcherrima Volkens [Illegitimate]; Ixora volkensii Hosok.; Ixora williamsii Sandwith);
.
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.

Photographed from Kashlsa College Botanical Garden, Delhi in August
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
Ixora ‘dwarf’ from Paras nursery Panipat
it is Ixora coccinea or Ixora taiwanensis?
it was about 6-10 Inch high only
Nurserymen says this Chinese Ixora or dwarf Ixora
pls validate I hope Ixora casei I think you are right Sir, the id finally resolved . Rubiaceae Week: Ixora casei ‘Super King’ from Delhi: syn: Ixora duffii T. Moore
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.
Commonly cultivated in Delhi for its scarlet red flowers. Photographed from Khalsa College campus. . Rubiaceae Week: Ixora casei Hance from a Nursery in Panipat: Many thanks … for showing this Ixora. Ixora species are very confusing – especially those found in gardens. Yes …, i agree with you, Ixora sps R really confusing.

Habit : Cultivated Which Ixora ??
Pl. check
To me appears close.
Leaf patern indicates to Ixora coccinea. Leaves appear to be petiolate. This is not there is I. coccinea.
Ixora coccinea : 7 posts by 3 authors. Attachments (2)- around 950 kb each. 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. I thought it was not in India. OK for Ixora casei. .
[efloraofindia:33098] Ixora fulgens from Delhi : Attachments (3). 21 posts by 5 authors. I also think this plant is Ixora fulgens Roxb because I used to have this plant in my terrace garden but later died. If stipules are deciding factor, then my second photograph clearly shows nearly 7-9 mm long interpetiolar stipule, triangular at base and narrowed above. 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 . 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 Ixora fulgens is a different plant with much narrower leaves
Here is another evidence that our plant is not I. fulgens (syn: I. salicifolia): 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, … indeed very normal for the delicate anther to fall off during due course of pollination / or obvious lifecycle of the flower. 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.
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. 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. How about Ixora Chinensis. Please check the link. In I. chinensis petals are obtuse at tip and leaves not with petioles. please delete this entry and shift discussion under I. casei, because same plant has already been posted separately as I. casei. I. fulgens a distinct plant has also been posted separately. .

Habit : Cultivated Ixora casei Hance ?? Interesting. Sorry to be awkward! Ixora casei seems rather rare.
I have never knowingly come across it.
Is it found in India?
Native distribution areas:
How do you know it is that one rather than the common Ixora coccinea?
Missuri botanical garden… Quote…”Noteworthy CharacteristicsIxora casei, commonly called flame of the woods or everblooming ixora, is an evergreen shrub that that typically grows to 6-9′ tall. It is native to the Caroline Islands (Micronesia), but is now widely grown in tropical areas around the world. Woody stems are clad with opposite, sharp-pointed, elliptic to oblong, bright green leaves (each to 10-12″ long). Tubular, 4-petaled, bright red flowers bloom in coyrmbose cymes (each to 8″ wide) throughout the year. Flowers are followed by round dark purple/black fruits (drupes).”
Quote … “Noteworthy Characteristics Ixora coccinea, commonly called flame of the woods or jungle geranium, is a rounded evergreen shrub that that typically grows to 4-6′ (less frequently to 10′) tall. It is native to India, Sri Lanka and southeast Asia, but is now widely grown in tropical areas around the world. It has become a very popular flowering shrub in southern Florida. Woody stems are clad with opposite, leathery, elliptic to oblong, glossy, dark green leaves (each to 4″ long). Tubular, 4-petaled, bright red flowers bloom in coyrmbose cymes (each to 5″ wide). Primary bloom is in summer, but sporadic bloom occurs throughout the year. Flowers are followed by round dark purple/black fruits (drupes).” Cultivated in India !
