BEAUTIFUL FLOWERING VINE AT CHANDIGARH'S NAGAR VAN

[vikram jit singh]

Dear Mr. Garg,

Could the members of this esteemed group help confirm the identify of a beautiful flower growing on a vine at the City Forest/Nagar Van, Chandigarh.

The vine is currently in bloom and was identified by a flower enthusiast as Aristolochia elegans.  

Best regards,

Vikram Jit Singh

Looking at only 2 images it looks more like A. elegans.

[Carmelita]

I'm sorry. I was typing while not quite awake. I meant to type A. grandiflora. I apologize for any confusion this may cause.

Thanks for the cues on ID.

Could the members assist in shedding light on two possible aspects of this vine of the Aristolochia:

1. Since it is an exotic, does it count among the invasive species that stifle or overwhelm native Indian species of flora?

2. Does this vine ultimately 'choke' the tree or sap its strength, ie, is this vine a parasitic plant?

Regards,

Vikram Jit Singh.

 I'm not certain if it is A. elegans or A. grandiflora.

That being said, A. elegans escaped cultivation and is considered to be an agricultural weed in Australia and in the Southern U.S. Also look for printed information using the synonym A. littoralis.

In the Himalyas it has the ability to displace the native A. acuminata and A. indica and A. manchuriensis.  

Certain butterflies depend on the native A. vines and the A. elegans has the ability to kill/poison the butterflies.

Carmelita you are right

Difficult to say without side views and some measurements

I don't see a tail.... rules out A. grandiflora

These are the pitfalls of mom and pop photography based diagnosis

Thank you for the guidance.

Is there any research paper on the vine's toxicity, invasive capabilities, its occurence and impact in India?

Thanks, Sushain ji, Camelita ji and Ushadi for the id.

I also think it should be Aristolochia elegans Mast. as per keys at Lucid Central and comparative images at Aristolochia‎
