Aarti Ji,

Attached here FI description and Icones plate relating to T. grandiflora Roxb. I think inflorescence of T. grandiflora Roxb. is not featured by long drooping elongated raceme like the T. laurifolia Lindl. But, my view is personal only, because following eflora does not support my view -

• http://keyserver.lucidcentral.org/weeds/data/03030800-0b07-490a-8d04-0605030c0f01/media/Html/Thunbergia_grandiflora.htm
  
• http://keyserver.lucidcentral.org/weeds/data/080c0106-040c-4508-8300-0b0a06060e01/media/Html/Thunbergia_laurifolia.htm
  

Moreover, cultivated form may take any character deviated from the wild form.

Going by the above site, and also with old lit. I have found in the net there is no other way to visually differentiate the two species except for the leaf, petiole, flower size.

Going by the leaf shape, texture (dull against shiny?) I would rather vote for T. laurifolia Lindl.

I may be wrong suggesting the above.

Thank you

Well Didi, Garg Sir, Mahadeswara Sir, Aarti Ji,

from my part I am not opposing any suggested ID.

I gave my view because I thought leaves in Thunbergia-JU-P1010039.jpg is xerox copy of http://keyserver.lucidcentral.org/weeds/data/080c0106-040c-4508-8300-0b0a06060e01/media/Images/Thunbergia_laurifolia/thunbergia%20laurifolia2.jpg 

of Laurel Clock Vine. - http://keyserver.lucidcentral.org/weeds/data/080c0106-040c-4508-8300-0b0a06060e01/media/Html/Thunbergia_laurifolia.htm.

Thank you

Regards

[Ushadi Micromini]

iti

this is not anybody's phd or even MS thesis

I have wasted enough time on this case

I am inclined to let it be...
lets close it
and mark it as complete if Gargji so desires...

when I run into one of these I'll take my usual umteen pictures with rulers and then we will see...
hopefully comparison of both species will be found soon...
Thanks Surajit

bye

My opinion is Thunbergia lauriflolia !

Thank you

Saroj Kasaju

[Gurcharan Singh]

Yes Saroj ji you are right

There has been lot of discussion whenever T. grandiflora or T. lauriflora was uploaded by any member. Here are the differences

Thunbergia grandiflora                                                       Thunbergia laurifolia

1. Leaves ovate, to 20 cm long, angular toothed,            1.  Leaves ovate-lanceolate, to 12 cm long, much longer than broad

almost as broad as long. 

2. Leaf base deeply cordate                                                2. Leaf based narrowed or shallowly cordate

3. Pedicel 4-5 cm long                                                          3. Pedicel 2 cm long 

Here are my two plants from Delhi

Thanks Saroj Ji.

I seem to have missed your reply earlier.

Aarti
