Vijayji,

I suppose this to be as P. orientale. Ochrea with leaf like wing is an
identifying character clearly visible in your first foto. The sps. is
very common in Assam and Arunachal also.

What do u say??

Regards,
Ritesh.

Dear Vijaysankar,
I am not able to convince myself that this is Polygonum molle, from
the overall appearance. Also, the leaves of P. molle have wedge-
shaped (cuneate) base, whereas the base of the leaves of your plants
are flat to heart-shaped.
Am not able to give much suggestion.

Thanks Tabish ji & Ritesh ji for pointing out the blunder. I was careless in idying this i think. Agree with Ritesh ji's id.

With regards

Vijayasankar

[Gurcharan Singh]

Now better placed as Aconogonum molle (D. Don) H. Hara (syn: Polygonum molle D. Don).

If this is Persicaria orientalis (syn: Polygogonum orientale), then perhaps my Kashmir plant needs recheck. Perhaps Ritesh ji can help.

I can upload more photographs if Ritesh ji wishes.

Thanks for the update Gurcharan ji. This is why taxonomy is considered a dynamic subject.

 

May be your plants are of hybrids, let's hear from others.

With regards

Vijayasankar

[Ritesh Choudhary]

Thanks for the interest Gurucharanji,

I agree with Vijayji views! May be your plants are hybrid. I also had
a doubt on my Arunachal's plant. I carried out mol. systematic studies
on the same and the sequences are 100% matching with the NCBI data
available for P. orientalis.

Regards,
Ritesh.
