ID of Polygonum!:  I require your help in identification of these varieties of polygonum.  The first three photos look very much different from the last snap polygonum4 which looks different.  I strongly suspect it to be Polygonum barbatum.  I require your help in identification of this variety of Polygonum.  Do help me out with this identification.
Please check for Polygonum glabrum (Persicaria glabra).
I am also thinking that this could be P. glabrum.
Please check the following;
Nut biconvex- P glabrum
Nut trigonous P. barbatum
But, according to gamble, there might be biconvex nuts among trigonous nuts so check for the presence trigonous nuts in the fruiting inflorescence.
Further,
Bracts not ciliate on the margins . P. glabrum.
Bracts ciliate on the margins - P barbatulum
Ocreae (A sheath formed at the node of a stem by the fusion of two stipules) 2-4cm long, tubular, glabrous, truncate at mouth - P glabrum
Ocreae 1.5-2.5 cm, tubular, strigose (Having stiff, straight, closely appressed hair), with very long ciliae at the mouth- P barbatum
Hope this key would be helpful.

Persicaria glabra (Willd.) M.Gómez (Hooghly):  (10 images)
This seems to be the :-
  • Persicaria glabra (Willd.) M.Gómez of The Plant List
  • Persicaria glabra (Willd.) M.Gómez of GRIN
  • Persicaria glabra (Willd.) M.Gómez of FoP
  • Polygonum glabrum Willdenow of FoC & Flora Indica
It is interesting to note the Style of this plant :-
  • Styles 2 in FoC -
  • Styles 2 in FoNA -
  • Styles 2, rarely 3 in FoP -
  • Style three-cleft in Flora Indica
These photos were shot on the bank of Hooghly river (The Ganges) in Chandannagore, Hooghly, on 22/02/2013.
Please, also note that neither of the two pictures in my earlier post, is Persicaria glabra (Willd.) M.Gómez, because leaves of Persicaria (Polygonum) are alternate -

Yes! Persicaria glabra from me too. Thanks for sharing ...
Very good photographs.  
You have clearly shown a specific character of the family (Images DSCN 143 to 146).
Ochrea, commonly spelled ocrea, is a structure formed of stipules fused into a sheath surrounding the stem. It is a diagnostic character in the Polygonaceae.
Thanks for your comments ...! Would like to share that presence of ochrea is not characteristic to the whole Polygonaceae family rather specific to the subfamily Polygonoideae only. It is absent or rudimentary in members of the subfamily Eriogonoideae.
Great ... I noticed a thing; shared on the group; and ultimately got more information. I am happy to be a member of this interactive forum with so many talented members who are ever ready to share so much.
Even the Ice cream creeper Antigonon leptopus is said to be devoid of Ochrea I suppose.
Yes Sir...you are very correct. More we share..more we learn!
eFlora is a great learning experience for me too...and many thanks for taking this positively.
Never noticed that Antigonon leptopus are devoid of ochrea. Fl. N. America mentions size of ochrea in the same plant as 0.2-2 mm.
Thanks ... I know You are the expert in Polygonaceae.
My sentence about Antipogon was based on some earlier discussion where ... has replied to one of my query related to the family. (Somehow I can't find that thread now...may be it was with my earlier mail ID)
I checked your link too. It stimulated me to dig in further but couldn't find much.
I think you only will come out with some conclusive statement related to Antigonon leptopus.
You are also correct! Antigonon leptopus belongs to the subfamily Eriogonoideae.
As stated earlier, ochrea in subfamily Eriogonoideae is either absent or rudimentary. Same is true for A. leptopus where ochrea is a very small (0.2-2mm) membranous structure that may not actually be well defined as 'ochrea'.
Requesting you to have a close look on this herbarium sheet. You will find the answer.

Please help to id this species of Polygonum
I have only these pics..
Eciliate ochrea and glabrous character are pointing towards Persicaria glabra.
Thanks ..., I was not very sure, though tentatively I was having same opinion..
Probably it is not from the altitudes of Chakrata which is temperate zone where P.glabra rarely reaches.
Thanks for pointing out ... this may be from a lower area on the way, I will try to make out exact location..

Kindly validate.
Yes! Persicaria glabra from me too!
The Plant which has been uploaded by you is Persicaria lapathifolia
Thanks for your opinion ...!
My identification was based on the glabrous character of the plant and the absence of blotches on the leaves which are generally present in P. lapathifolia.
Would like to hear more from you.

Ah great. since persicaria and Polygunum are both KNOTWEEDs in colloquial herbal ids and food foraging, how does one differentiate them botanically. I will greatly appreciate help in this.
... or anybody else that knows this, please tell us.

Request for I'd of Polygonum from Bilaspur. Photographed today. (25.9.20)
Persicaria decipiens (R.Br.) K.L.Wilson ?? 

your I'd is correct.
Persicaria glabra 
Thanks ... I will check. Could also be P. hydropiper.
This is Persicaria glabra (as identified by ...) rather than Persicaria decipiens or Persicaria hydropiper, as per images and details herein.
