Rubiaceae – Ixora sp. for ID : 6 posts by 6 authors. Attachments (1).

Location : Lengpui, Mizoram. Altitude : ca. 400 m. Date : 21-04-2014.
Habit : Small tree or shrub with white fragrant flowers. Habitat : Wild.


Could be Ixora brachiata.


Ixora nigricans


to get a specific id we need close up pics of flowers and buds


No reddish hue observed as in FoI links –

  1. http://www.flowersofindia.net/catalog/slides/Gorbale.html
  2. http://www.flowersofindia.net/catalog/slides/Black%20Ixora.html
Insufficient data to explore further.


There is no distribution of both suggested sp. in Mizoram!


What are the species of Ixora reported in your area?


Ixora acuminata, I.roxburghii, I.subsessilis & I.undulata are reported in Mizoram


Thanks, … May I request you for a high resolution image and other images, if any.




I have snapped these wild flowers from Karbi Anglong (Assam).. I think its  Ixora nigricans.


May I have the keys from your area?



After going through different resources like keys above, efi, GBIF, POWO and CoL, I think plants from Sawmliana ji and Binay ji, will be Ixora balakrishnii Deb & Rout (syn:  Ixora roxburghii N.P.Balakr., nom. illeg.;  Ixora villosa Roxb., nom. illeg.) as per Catalogue of life and POWO and GBIF– specimen 1 and specimen 2

Another closer one is I.subsessilis as per GBIF, but different.

Ixora undulata and Ixora thwaitesii (syn: Ixora acuminata Thwaites) look different.


Both species (Ixora nigricans and Ixora balakrishnii) are quite close and reported from Assam.

If you can find out the keys, the images can be finally sorted out.
I am unable to get them on the net.
Till them I am keeping it as Ixora balakrishnii Deb & Rout

MS April,2016/23 Pavetta sp. for ID : 6 posts by 2 authors. Attachments (2)

Location : Lengpui, Mizoram
Date : 19-04-2016
Habit : Shrub
Habitat : Wild


Pavetta species so far in efi 


Might be pavetta species


Is it Pavetta indica ?


It  is an Ixora species. Pl. check with comparative images of Ixora species in efi at Ixora. I think it does not match with any of the species here.

It is better to find out which species are found in Mizoram from local flora.


The stigma is entire and hence it can be aspecies of Pavetta only. Most probably P. indica


Hope you’re …


Pavetta indica looks good for me as well.!


I do not think matches with images at Pavetta indica

What are the species reported from your area ? Any keys ?


Pavetta indica var. glabrescence  & var. tomentosa, P.subcapitata are recorded in Mizoram.



After going through different resources like keys in another thread: Rubiaceae – Ixora sp. for ID, efi, GBIF, POWO and CoL, I think plants from … will be Ixora balakrishnii Deb & Rout (syn:  Ixora roxburghii N.P.Balakr., nom. illeg.;  Ixora villosa Roxb., nom. illeg.) as per Catalogue of life and POWO and GBIF– specimen 1 and specimen 2

Another closer one is I.subsessilis as per GBIF, but different.
Ixora undulata and Ixora thwaitesii (syn: Ixora acuminata Thwaites) look different.

Also P.subcapitata looks different as per GBIF.


Ixora nigricans ?


Is it listed in your book?


No, sir
