Persicaria sinuata (Royle ex Bab.) Rajbh. & R.Joshi, J. Jap. Bot. 70(6): 332 1995. (Syn: Polygonum sinuatum Royle ex Bab.);
.
As per efi thread:
This species is often confused with its very closely related sister species known from Eastern Himalayas (P. runcinata) from which it is different in having much smaller size of all parts including leaves, creeping habit not erect and almost glabrous nature except peduncle which is sometimes puberulent. Also the inflorescence heads are generally darker pink in P. sinuata and mostly (but not always) pale rosa in P.runcinata.

Persicaria sinuata (Royle ex Bab.) Rajbh. & R. Joshi is an uncommon creeping herb in subalpine- alpine zones in Uttarakhand. It is found on moist slopes or along streams.
Image search in Google indicate that there are no (or very few) photographs of this species on web. It is also not represented in eFI and, therefore, an addition to our database.
The species can be distinguished from others by its peculiar lobe in leaves as visible in photograph.
Photograph shot in Sunderdhunga Valley, Bageshwar District of Uttarakhand.

A unique post …

Thanks for this unique upload …! I’ve seen this plant only on herbarium sheets. 🙁

This species (Persicaria sinuata Polygonaceae) is represented by a lone image of vegetative state of plant posted by me. This time I was lucky to have flowers in this species.

Present image was photographed in Ralam valley Pithoragarh district at an elevation of about 2800m along a stream on 3rd September 2017.


Agreed with … ID. This is Persicaria sinuata (Royle ex Bab.) Rajbh. & R.Joshi. Morphologically close to Persicaria runcinata (Buch.-Ham. ex D. Don) H. Gross

Family: Polygonaceae.

I think there is a TYPO error from …
The posted plant is Persicaria runcinata (Buch.-Ham. ex D.Don) H. Gross

Earlier the same was posted by …: efi thread


I certainly made a mistake … Thank you for correcting me and pointing me in the right direction.


This is  actually Persicaria sinuata (Royle ex Bab.) H.Gross which is often confused with its very closely related eastern himalayan sister species P. runcinata please see attached post for differences.
… please also correct Polygonum runcinatum page name to Persicaria runcinata (Buch.-Ham. ex D.Don) H.Gross which at present is its accepted name.

Persicaria sinuata
(Royle ex Bab.) H.Gross
Family – Polygonaceae
Photographed near Dharamshala, HP
In late August 2019
Habitat – Subalpine rocky in moist places
This species is often confused with its very closely related sister species known from Eastern Himalayas (P. runcinata) from which it is different in having much smaller size of all parts including leaves, creeping habit not erect and almost glabrous nature except peduncle which is sometimes puberulent. Also the inflorescence heads are generally darker pink in P. sinuata and mostly (but not always) pale rosa in P.runcinata

The images present on P.runcinata page on our site from Himachal Pradesh is actually of P.sinuata as other species (P.runcinata) i think is not so far known from Western Himalaya as it is more Central and Eastern Himalayan species. I will comment separately on those misidentified posts for correction.
