Location- Place, Altitude, GPS- Victoria memorial, Kolkata
Habitat- Garden/ Urban/ Wild/ Type-Urban
Plant Habit- Tree/ Shrub/ Climber/ Herb- Tree
Height/Length- 40 Feet
Leaves Type/ Shape/ Size- Large (10-20 cm) like Jatropa curcus

Do you have photographs of the under surface of the leaves ?
I want to say tis is Pterospermum acerifolium 
i.e. Kanak champ, but would like to see a few more details of the leaves and later in the season (like in aufust) the flowers.
there is some write up on our page about the leaves being peltate and orbicular but the case we have shows wide variation in that characteristic.
Most of the tree in victoria memorial have a small metal plate with a number etched, did you see one on this tree?

Doubtful Id. Looks different ...
I agree. the leaves and their grouping, insertion of the petiole all had me worried.
... i was not asking for the name label, i know they have a problem. i was just asking for a number plate its about 3 inches by three inches mostly because it seems there is a lot of cutting down of tree going on in the background. wanted to know if you saw any number on this tree. this tree has me worried, it seems it may go on the chopping block soon. thats all
only other possibility can think of is a tree called Berrya cordifolia var. mollis.
These is one in Shibpur botanical garden.
And Bentihill says there was one near Tollyclub main gate and what is now the exide mor...???
ps internet including our website is not much help in that that  nobody includes great pictures of the leaves and bark.
Difficult to say. Kleinhovia hospita comes to mind without flowers and fruits. 

Quite possible sir.  
yes Kleihovia ia what i entertained first but the leaves did not seem to be of the right size though

Yes ..., not Kleinhovia at all. The photographer is requested to take photo of flowers.

Possibility of any Sterculia (even Firmiana)?

you may be onto something. the feature here that was very evident was the crowding of the leaves at the very end of the branches. that seems to be point we need to do the differential diagnosis. well onto research
Another guess is Cochlospermum religiosum (L.) Alston 

... I compared the phtographs of Cochlospermum religiosum taken by me in Mysore. They are different.

Can Jatropha curcus attain such height and tree like structure? 

no. it seems. i have searched long and hard. nothing to be had on the internet but never say never
---
looking closely at the picture above... there is a metal plate like something. may be a second visit by ...  will get us a number 
with that number we could ask the memorial staff!
No. Nevertheless, it grows up to 10 feet as observed in Mysore where it is found in wastelands. Anyway the photograph does not look like J. c.  It is different according to me. 

It is Gyrocarpus americanus (hernandiaceae), soft tree, frequently found in the dry foot hill areas

that would make it the helixcopter tree
1: ... picture of that tree is in flowers of India site. the leaves don't match
but his case on efloraindia shows many pictures and the leaves indeed are bunching up at the tip of the branches although they are simple in outline  not like jatropha leaves.
2: on our own page for 

Gyrocarpus americanus

the few cases we have shows a wide range of leaves sizes and outlines
and there had always been a chaos and discussions of differential diagnosis based only on leaves.
===
we  have the same problem here we only have leaves shape and the fact that they are bunching up at the end of branches.
we need flowers and or seeds.
==
i would not wish this to be the final say
nor would i like to mark this case as complete 
(because i find that no further discussions are possible) (one can only write to the last person on the thread before it was marked complete.)

I agree with ... The issue is confused now. Does the tree has  different shapes of leaves.  

No confusion sir, it will have entire to 3 - lobed leaves.

i second ... sentiments and thank ... but i hold an open mind about the final diagnosis. need to find more data, leaf pictures showing diverse outlines or descriptions or herbarium sheets of various leaves. its by no means a closed or completed case
to me it is Firmiana sps. also looks closer to Dombeya sps.

Thanks .... I do not think it is Kanak Champa as I am very familiar with it. In fact I have one at home. Kanak Champa usually blooms in March(attaching a photo taken on 17-March this year). Also I did not find any plate but I'll look for it again when I visit next.
Honestly, the name plates are not that authentic. I have found many tress are wrongly labelled in Dhakuria and even in Victoria.
Thank you Satish . Your input means a lot to us. OK. now we are getting somewhere.
all the viable choices we have so far seem to  point to a member of malvaceae family
Dr Pardeshi: Dombeya sp family malvaceae shows  four species  in our list 
                     Firmiana sp is of family Malvaceae shows two species  in our list 
DR Desai :    Berrya sp is of family Malvaceae shows two species on our list
Tapasda, Usha di, have considered are Kleinhovia is also of Malvaceae family.
Usha di thought it was Pterospermum ... Debjit said its not because he has one himself, and this is not it.
Gargji suggested could it be:  Cochlospermum religiosum of  family 

Bixaceae

but Usha di says its not, because she had one and its not at all similar.


and Santhan ji said it is Gyrocarpus americanus  of family Hernandiaceae
and he says three types of leaves can be seen in this tree
although what we see on the net and what we have here are not matching. 
Original question was could it be related to could it be  Jatropha curcas of euphorbiaceae family
Interesting 
gives us options to think about and search
Firmiana colorata?
Pl. check details and images at Firmiana colorata
Just the leaf details is the problem sometimes.
thats the case here it seems.
... has shown a case that is almost at the bottom of the page 
and ... had shown tree base in her case. May be ...
I think he would know. ... can you please look see?
