Hello : delicate beauty from Mahabaleshwar : Persicaria nepalensis ( Polygonaceae):
Persicaria nepalensis (Polygonaceae) : Small beautiful annual herb. This delicate beauty I clicked at Mahabaleshwar on 15th Sept. 2012. Mahabaleshwar altitude is around 4400 ft. I had also spotted this plant at Raireshwar (approx same altitude).
persicaria nepalensis, mahabeleshwar: Yes … Nice photographs While looking at the mahabeleshwar photographs, I realised that there were some of the pink variety as well.
Attaching one of those
These flowers were tiny and very easy to miss

Persicaria nepalensis (Nepal Knotweed)

15-16 August 2015
I found this one on the ground–not tall like the others, leaves larger, the red edges more prominent. Looks slightly different from the others but I can’t think what else it could be. Please advise if I am wrong in putting it here with P. nepalensis.
Yes! All pictures belong to Persicaria nepalensis (Meisn.) Miyabe. Family: Polygonaceae I photographed this yesterday. Is this also P. nepalensis or a different knotweed? Unlike my other photos last year this one has very prominent black V marks but I understand that these can be variable in a species. Please advise. 2 images. I think this is again Persicaria nepalensis. Winged petioles are characteristic.

Thanks for your reply. This looks close to Persicaria nepalensis (Meisn.) H. Gross, but I cannot confirm based on these images.

   Polygonaceae Fortnight- Polygonum? for id from Gori valley area:: NS May 30 : 11 posts by 5 authors. Attachments (3).
This delicate herb was shot from Gori valley area.. still lies unidentified with me.. tentatively I have placed this under Polygonum Polygonum nepalense Meisn. is an interesting plant. It comes under P. alatum Ham. in FBI. It was also referred to in P. khasianum Cas. Wondering how this plant missed my attention!
For me this is Persicaria sagittata (L.) H. Gross.. characterized by the sagittate leaves.
Thanks for sharing the beautiful images Sir! Thanks … for inputs.. thanks … for identification… Thanks once again …, but how do you explain – “perianth white ….. or red, ….. not becoming blue” as in FoNA, and also absence of at least 5 mm petiole, besides some other points? Thanks for your efforts … Perianth color is variable and taxonomically less important (at least in Persicaria)…this blue seems to be an intermediate between white and pink. Further we can see the terminal leaves here with no petiole….’ll get them as you go down. Thanks a lot …, I am really grateful for addressing my concern. I put down my explanation (in favour of P, nepalensis) –
I would request you to check Flora of British India also, because there are several var. under P. alatum Ham. and give your final verdict which I will accept whatever it may. Thanks a lot … for your concerns. I accept … Thank you very much for spending some time over it. Yes this plant looks very different from … plant in which although upper leaves are clasping, the lower clearly show leaves with winged petiole. … plant is quite different, much more delicate, with clearly sagittate leaves. Thanks …., for introducing an interesting member of Polygonaceae. I think Persicaria nepalensis only as per images and details herein and as per discussions at SK120OCT02-2016:ID I think this is P. sagittata. It does not match with P. sagitata as per POWO specimen 1 and two and GBIF specimens from Nepal and India– one and two Thanks for your comments! May I request … to upload more pictures if available?

Sharing some pictures for ID shot at Chandragiri Hill Kathmandu on 19 September 2016 at 8200 ft. Could it be Fagopyrum or Persicaria?? Thanks for sharring …
This is interesting! Looks close to Persicaria sagittata (L.) H.Gross. Please share more images of leaf, if you have. Inserting some pictures as advised.
Attachments (13) Yes! It looks like Persicaria sagittata (L.) H. Gross (Polygonaceae) to me. I feel this looks different from P. sagitata since the stem does not have downward spines. You appear to be right as it does not match with P. sagitata as per POWO specimen 1 and two and GBIF specimens from Nepal and India– one and two.

Persicaria. Which one?
Thanks … for sharing these images.
I think this is Persicaria sagittata (L.) H.Gross Polygonaceae
Please also check the high resolution image of DSC_0451 for the presence of recurved prickles. There seems to be mixture of P. nepalense as well. DSC_457, 459, 448 and 450 are not matching well with P. sagittata. They are probably P. nepalense. P. sagittata is a polymorphic species. Pl see the quote from Fl. China:
Polygonum sagittatum s.l. is an extremely variable species and known from both Asia and North America. Some authors have pointed out, on the basis of differences in achene surface and leaf margin, that North American populations are separable from Asian ones, and have treated them as two distinct varieties of P. sagittatum, or as two distinct species: P. sagittatum in North America and P. sieboldii in eastern Asia. In Park’s previous taxonomic monograph of P. sect. Echinocaulon(Syst. Bot. 12: 167–179. 1987; and Mem. New York Bot. Gard. 47: 1–82. 1988), P. sagittatum and P. sieboldii are recognized as conspecific mainly based on flavonoid chemistry and also the observation that North American plants are well within the range of variability of eastern Asian ones. However, the recent molecular analyses of North American and eastern Asian populations of P. sagittatum (Park, in prep.) show that these disjunct populations are genetically somewhat divergent from each other. The degree of genetic divergence, however, strongly suggests that they can be recognized either as a single polymorphic species (P. sagittatum s.l.) or two distinct varieties of P. sagittatum, but they can hardly be treated as two distinct species.
I think it is one plant only.
Enclosing link for earlier post for cross reference.
On closer scrutiny of posted images, I also feel they are from the same plant.
I should I take these as Polygonum sagittatum ?
Please also check the high-resolution image of DSC_0451 for the presence of recurved prickles.
Image quality not so good. Please let me know if it is ok ? I think Persicaria nepalensis only as per images and details herein and as per discussions at SK120OCT02-2016:ID I guess you are right Yes, P. nepalensis for me too. . Please have a look on this plant from Poonch jandk: 2 images.
