I think you have inadvertently mixed up the filenames ... T. laurifolia and T.grandiflora
No ... They are properly uploaded. You please observe the photographs carefully and compare with Hawaii website links sent with the other mail
... I confused myself !!
Thanks for bringing up this discussion. According to the description on
http://www.hear.org/pier/species/thunbergia_laurifolia.htm
http://www.hear.org/starr/hiplants/reports/pdf/thunbergia_laurifolia.pdf
the leaves of Thunbergia laurifolia have margins almost entire or slightly toothed. The same can also be seen in pictures on
http://www.hear.org/starr/plants/images/species/?q=thunbergia+laurifolia
http://www.hear.org/pier/imagepages/thumbnails/thunbergia_laurifolia.htm
In your pictures, and also on those on FOI, the leaves are strongly lobed. Also, the base of the leaves of T. laurlifolia is supposed to be obtuse or slightly heart-shaped. The leaves in your pics and those on FOI have deeply heart-shaped bases.
Hence I think all these are Thunbergia grandiflora only.
I request you to kindly compare my plant with the herbarium specimen of your first link and Last photograph of your third link.
I am uploading fresh photographs of distant shots of leaves of two species as uploaded by me as T. grandiflora and T. laurifolia, respectively, for comparison. 
Id remaining undecided- Thunbergia laurifolia or Thunbergia grandiflora?
Those still having doubts about its identity are requested to view these links. Lobed and slightly cordate leaves are a common feature of T. laurifolia:

Thunbergia grandiflora of Acanthaceae family

This is thunbergia grandiflora...
... look at the leaf very carefully and take en face photo of one complete leaf to show leaf margin and attachment to the stem.. for your own files and memory.. leaf shape is unique... even if flower color shows a great deal of variation over time and regions... the leaf almost stays the same....
I have found these in Miami, Fl, Key west, florida, california... naturalized and in gardens and in snowy countryside in botanical gardens, in England at kew and of course all over India... in Bengal we get several colors... of course always in the blue- bluish white to bluishpurple (like yours) ..... develops seeds in Key west fl but not seen any seedpods on any of the hundred or so vines I keep an eye on off and on for three years in in several neighborhoods of Kolkata recently partly because local women do not leave mush after they pluck every darn flower for worship or just because... ( its a
disease in India) ... GOD never wanted soooo many flowers as to deplete the gene pool... ) ... or we dont have appropriate
pollinators... even if we had pollinators, they would not develop a habit of coming to that vine if they were not assured of some good appreciable amount of nectar from a large numbers of flowers...
I would rather go with Thunbergia laurifolia
Thank you ... for identification. I have studied your previous posts on this matter and found this excellent explanation by you how to differentiate the two
In the thread you wrote
The leaves of T. grandiflora are conspicuously cordate, nearly as broad as long, with longer corolla tube.
T. laurifolia. Note that leaves are much less wider as compared to length, and  not cordate at base.
In both species the flower varies from blue to white.
In this thread you wrote
Uploading fresh photographs of distant shots of leaves of two species as uploaded by me as T. grandiflora and T. laurifolia, respectively, for comparison.
Really beautiful pictures made it very easy to understand
When I studied this plant on the net before uploading I found info (I am sorry I do not have the link address) saying that these 2 are synonyms. but when you identified it as T laurifolia I said no it means these 2 are different and studied your posts again
I think T. laurifolia is the accepted name for T. grandiflora var. laurifolia as per the plant list.
But the 2011 revision of Flora of China says Thunbergia grandiflora.
While searching for T. grandiflora I couldn't see the species name as such in the plant list

It was discussed earlier also on the group, but here it goes
Thunbergia grandiflora                                          Thunbergia laurifolia
Leaves ovate, to 20 cm long, angular toothed.        Leaves ovate-lanceolate, to 12 cm long
Leaf base cordate                                                    Leaf based narrowed
pedicel 4-5 cm long                                                  Pedicel 2 cm long
Please refer to my earlier posts. Thunbergia grandiflora Roxb. is now correctly known as T. alata Bojer ex Sims according to the Plant List.
I got it and I somehow didn't get that when I searched for the T grandiflora.
Cant believe that Thunbergia grandiflora and Thunbergia alata are one and the same...
where the literature says one from India and other from Africa with lots of distinct characters..
I am not getting convinced myself on T. grandiflora getting synonymised with T. alata. Please find attached herewith the recent revision (2011) incorporated with eflora of China.
Please share if someone has any relevant information regarding the same.
Thanks for Flora of China PDF.
Let us discuss our view points in academic manner and not get upset because some thing does not suite us. I had uploaded the plant as Thunbergia grandiflora only and appended this note:
Thunbergia grandiflora (Roxb. ex Rottl.) Roxb., Bot. Reg. 6: , pl. 495 1820. syn: Flemingia grandiflora Roxb. ex Rottl.
Woody climber with broadly ovate often deeply cordate leaves, angular-toothed, 3-5 nerved; flowers in drooping racemes, on up to 5 cm long pedicels, corolla blue, soewhat 2-lipped. Photographed from DU, Delhi
Common names: Blue trumpet vine, Bengal clock vine, sky vine.
The plant though closely related to T. laurifolia is treated as synonym of T. alata in Kew Plant List and perhaps in Schonenberger, J. 1999. Floral structure, development and diversity in Thunbergia (Acanthaceae). Bot. J. Linn. Soc. <http://www.tropicos.org/Publication/1172> 130: 1–36. Final comments can be made only after seeing this paper.
I had requested members to find out about this publication and then only we will make final comments. No one perhaps been able to get it, but can't ignore it if it has been adopted by the Plant List.
But as pointed out by ..., Flora of China publication is 2011 publication and we will follow it till any concrete results come.
Let us not be found by fixed ideas that I know this plant for last so many years and know it is different. Who by the way is challenging Nerium indicum being merged back into N. oleander. If we are scientists, let us have open mind like scientists be guided by reason and evidence.
Does we get Nerium in the Wild form??? from where, which state?

I think its Thunbergia grandiflora
On second thought I am now confused... looked at the leaves again
leaves in pic 1 and two have somewhat different shapes...
cant rule out Thunbergia laurifolia...
I think Thunbergia laurifolia as the leaves are slightly toothed. Also, the base of the leaves is slightly heart-shaped or obtuse.
Agree with Thunbergia laurifolia
Three features differentiate the species, lanceolate leaves usually less than 12 cm long and pedicel 2cm long in T. laurifolia. Here are typical plants
Leaves ovate-cordate, up to 20 cm long, pedicel 4-5 cm long in T. grandiflora
efi thread
The first photograph (leaves) and second (pedicels) suggest T. laurifolia clearly, other photographs create some doubt.
I some how have the feeling that most photographs on the net, including above one may not be a hybrids betwen the two species, as is also true for Campsis grandiflora and C. radicans, where these hybrids are placed with either species in most databases, including our FOI.

Also in typical specimens of T. laurifolia, the leaves are almost unlobed, rounded at base, and 3-nerved from base. They are deeply cordate, somwhat lobed or toothed along margin and 3-5 nerved from base.
Thunbergia flowers are sooo appealing that they crop up everywhere... Kolkata has many all in diverse areas... now I ''ll look at them more critically and photograph the leaves and pedicels with a ruler handy...
After my exam in dec I'll dig out my pics and post them esp so you can verify or put me straight... ha ha…

Is this Thunbergia grandiflora or Thunbergia laurifolia?
I get confused between the two.

I would also like to know how T. laurifolia and T. grandiflora are different, ...
Presently I do not know ... I have earlier thread where I placed mine under T. g., but I need to have a relook. However, one points favour mine - broad leaf as have been noted in http://keyserver.lucidcentral.org/weeds/data/080c0106-040c-4508-8300-0b0a06060e01/media/Html/Thunbergia_laurifolia.htm. But that is not enough surely.
I too have been under the same impression sir. The bigger leaved one being T. grandiflora. I may have also imagined a different shade to the flower as and when I came upon one but I think I would really like to know the true botanical differences! I will look too.
Here is my thread
Such cases are the reason I have been repeatedly asking people to  get the front and side views of flowers
front and backs of leaves
nodes
any special feature of the lead pedicle and of petole
and AND AT LEAST PUT FINGER IN THE PICTURE AT LEAST IN ONE OF THE SRIES OF THAT PARTICULAR PLANT
a ruler is the best, but in itsabscence a pen a pin even the camera lens cap with its name written .. so in case one need it one can measure the font and surmise
but alas... 
Yes Didi, only face of flowers is often not enough to decide the species.
Pl. see the differences: In efi thread
Thanks ..., what a discussion in that thread!
Based on Gurcharan ji's upload of T. grandiflora and key provided, this should be T. laurifolia and not T. grandiflora as I had first imagined due to the shape of the leaf base..
Kindly validate.

Thunbergia climber seen in a cultivated garden in Mumbai.
Is it T.laurifolia or T. grandiflora?
How to distinguish the two?
efi pages on Thunbergia laurifolia & Thunbergia grandiflora
In my view  yours is Thunbergia laurifolia. Thunbergia laurifolia is similar to Thunbergia grandiflora except that leaves are elliptical. Thunbergia grandiflora is similar to Thunbergia laurifolia But leaves are heart-shaped.
Thanks for the id and making me aware of the differences between the two Species.
