Ixora fulgens : 3 posts by 2 authors.

Many Indian books and Flora of Pakistan refer to Ixora fulgens as commonly cultivated species. This species has unlike I. coccinea slightly petiolate leaves with cuneate base (and not sessile and cordate as in I coccinea) and scarlet flowers with nearly 1.5 cm long corolla lobes. Does any colleague have a photograph of authentic specimen of this species. Another very closely related species is I casei (authentic description of this species is requested) with very narrow sharply pointed lobes. Many photographs appear to be mixed up in gardens and websites. We need to share our authentic photographs to sort out the material. There is a lot of variation in flower colour, shape of corolla lobes, but leaves appear consistent: sessile and cordate in Coccinea, rounded and sessile or subsessile in I chinensis and petiolate in I fulgens. Corolla tube length also shows some consistency.

Looks same, but for both my and yours we have also to explore I. casei, a very similar species. I cound not find the key.


There can be several differences between these plant which are very minute and sometimes regarded as  irrelevant by many taxonomists in some case but one difference I know which is more than enough to differentiate this two plats at a simple glance. Which is Ixora casei doesn’t have stipules (extipulate) whereas Ixora fulgens has stipules grasping the stem. I will still request to check out the fact again.


As the photos you have added shows the presence of stipules (stipulate) hence it is Ixora fulgens. Kindly validate.


… digging into I. fulgens has clarified this plant is not it.

Could be I. casei or may be else … on seaching through image results, observed that a structure, perhaps anther that is seen in my photos is not found in I. casei.
… have re-attached one of the photos with the query.


Anther is labelled fine by you. It is very common to see photographs in with anthers are fallen and we see only filaments. I don’t see anthers showing any difference.
