yes Cleome chelidonii, weed in wet land in Vidarbha
Cleome chelidonii (Ratnagiri Dist):
Here I'm sending some Photographs of
Botanical Name - Cleome chelidonii L.f.
Common Name - Celandine Spider Flower
Vernacular Name- Pan tilvan
Family - Capparaceae
Date - August 2012
Location - Rajapur, Ratnagiri, MH.
Yes ID is Correct, & its Identified by me.
I got this plant near pond region, in Konkan.
...  wet feet question compelled me to look down at the leaves in the distant shots, they appear linear and no where near Cleome, although flower is very much like a cleome.
It would be nice if ... uploads a photograph with leaves to allay our doubts.
Very beautiful photographs with habitat. Fruits and flowers confirm to be Cleome sp.
Thanks a lot - ... For ..., here i'm sending another some pics of d same plant.
For d identification I have refered FLORA OF MAHARASHTRA STATE - Dicotyledones VOL-1
I'm also sending scan copy of Flora which mentioned Cleome chelidonii L.f.
Kindly Please check n tell me, weather I'm right or wrong.
There is so much to know about Indian flora... yes I give you that flower is reminiscent ...
and the seed pod ... but such round seed pods develop in several plants I know of.. mustard is one that comes to mind...
the pic SDC10265-001.JPG shows that some animal is fond of grazing on it...
besides showing NOT A SINGLE CLEOME like leaf... at least to my eye.. I 'll await ... email
BIG Thanks to ... for raising the issue. It is Cleome simplicifolia
Here is another example of why it is important to upload photographs of leaves. Without the first photograph showing habitat, this plant would have easily gone into our records as Cleome chelidonii, a much similar looking in flowers except that here they are more lilac in shade than being purple. The simple linear leaves are highly distinctive of C. simplicifolia.
I also ignored the leaves being a distant shot, but thanks ... for detecting 'wet feet' which forced me to look at leaves below on the plant.
In my concern...I have too observed simple leaves in Cleome chelidonii, in addition it only occurs in aquatic places or in marshy land; while C. simplicifolia is comparatively small, prostrate one with ovate leaves, fairy occurs in mainland....
Please see the attachment below for C. simplicifolia.
So the correct ID for ... posted pics is C. chelidonii least as per 
This attached pic, is produced from the PHD thesis of Dr. V. T. Apradh (he is one of good frnd of mine) department of Botany, Shivaji University, Kolhapur. He has done PHD in Cleome. In addition, I have taken the picture of habit. SEM image was produced from the thesis too. He is very kind person so he made his thesis available online in the form of blog. I don't think it would be problematic or something. 
I think this can not be Cleome simplicifolia as the flowers appear to be larger. They are only 4-5mm in Cleome simplicifolia which is a very small herb. I think this is a bigger erect herb Cleome chelidonii  which is 30-60 cm tall. Probably she has missed to catch the rosette of basal leaves so they are not visible. What we see here are the upper linear lanceolate leaves.
Thanks Satish ji for correcting me fast
Let me put it this way. ""This is another example of why photographs without proper leaves can be confusing...........and where an internet upload (for me) can be more confusing".
Yes it can't be C. simplicifolia in which stamens are 10-12 in number. Yes the number of stamens do suggest C. chelidoni, but leaves are still a problem. I can't see a single palmate leaf in all plants seen, and description in FBI does not mention about simple leaves in C. chelidoni.
Perhaps a photograph showing lower palmate leaves and simple linear cauline leaves clinches the issue.
I would like to mention once again n all u can see d Habitat picture SDC10270.JPG & DSCN0448.JPG in which clearly seen the plant was grown on aquatic place in Konkan, After catching some snaps heavy rain was started there, thats why I was not able to catch the rosette of basal leaves, but as per my field observations I concluded it C.chelidonii only, apart from rossete leaves stamens are also suugested dat its only C.chelidonii & ... too agrred it - " Yes it can't be C. simplicifolia in which stamens are 10-12 in number. Yes the number of stamens do suggest C. chelidoni "
I would say many thanks to ... who uploded Morphological snap of C. simplicifolia.
It was a learning experience. For most plants II consult FBI which is fairly reliable, but does not mention simple leaves. I think I will also now buy Flora of Maharashtra.

Flora Identification. : 3 posts by 3 authors. Attachments (3)
Location-Birur, chickmanglore district, Karnataka.
Herb (Weak diffuse stem)
Leaf-Whorled (You can notice in one of the attached photo that whorled leaf modified into bract), Racemose (Corymb) or solitary axilary? Bi-sexual, Polyandrous, Syncarpous, Hypogynous, polypetalous, actinomorphic calyx.
Fruit- Dry dehiscent (Pod),
Is it Inflorescence?? or stem because the whorled leaf as on the main axis of inflorescence goes on modifying to bract like structure. Experts have to confirm.

It is Cleome chelidonii of Cleomaceae
