Polygonacae Fortnight: Polygonum microcephalum D. Don from Assam – KD MAY02 : 4 posts by 4 authors. Attachments (6).
Attached images are Polygonum microcephalum D. Don collected from Assam.
It is used as vegetable in Assam, known as Madhu-saleng (Assamese). Yes for P. microcephala. Common in Arunachal too. Thanks for sharing …
Polygonaceae member? Did you find this plant in wild? Or was it brought from outside and cultivated?
Because the capitate head, trianguar-ovate leaves with winged petiole are pointing to Persicaria microcephala… but that plant is distributed in E. Himalaya only. Wondering how it reached Bangalore. Comments awaited. It is very likely that this plant is the Persicaria sp. You have mentioned.

Persicaria …??
Persicaria nepalensis, I think. The flowers can be white or pink, leaves with winged stems clasping the stem, common here at 5000m. Persicaria microcephala (D.Don) H. Gross Thank you …! Polygonum microcephalum D. Don Thanks, … for the local names. Pl consider Persicaria microcephala as the accepted name. Thank you … I thought the Plant List gave the correct accepted name !
Please don’t rely completely on The Plant List. So many names are still unresolved there. The Persicaria and Polygonum mystery is almost solved based on recent molecular works. I hope The Plant List will get updated soon. What is this mystery? Thank you … Can you please suggest any link we can fully rely on ? For Persicaria, GRIN is better than TPL. Though none of them is 100% correct.

Persicaria …..??
Persicaria microcephala (D.Don) H.Gross is the closest match for me. The description provided in Fl. China shows slight deviation with the herbarium samples kept in Kew.

Persicaria microcephala (D.Don) ?? or subsp.??
Please note spikes in the margin of upper leaves.
POWO says specimen collected from Nepal but did not mention distribution for Nepal.
To me appears doubtful as per images at Persicaria microcephala Presence of eight stamens (_DSC0398) and truncate ocrea (_DSC0404) are pointing towards Persicaria microcephala (D.Don) H. Gross (Polygonaceae).    Flora of Arunachal Pradesh- Namdhapa near Miao- Herb 8 for Id- JM: – Do you have some more photographs with basal leaves? – I have only this picture & no picture showing basal leaves. Here are a few links of Polygonum microcephalum: http://plants.jstor.org/specimen/bm000521959 (Type) – Polygonum species. But does not look like P. microcephalum. One more doubt. The third picture looks different from the first two. Appears close as per images at Persicaria microcephala .    Id help please from Ri-Bhoi Meghalaya: This herb is called Jajew siej in the local language and is found under canopy in open forest. This is a wild edible
Persicaria microcephala (Wall. ex D.Don) Sasaki Yes, possible as per images at Looks like P. microcephala. Flowers needed to confirm the ID.

Persicaria …???
Some species of Persicaria….? Does not it look like SK362 02FEB-2017:ID ?? Yes to me appear close. Thank you but ID still pending !
It is not yet properly identified so far I guess !
I am afraid the flowering pattern and leaf pattern/ shape looks different to P. hydropiper.
Persicaria microcephala (Wall. ex D.Don) Sasaki ?? Yes, appears close as per images at
https://efloraofindia.com/efi/persicaria-microcephala/ There is a closely related species as
https://efloraofindia.com/efi/persicaria-greuteriana/ Google AI give the following differences between the two: Persicaria greuteriana and Persicaria microcephala are closely related, often confused perennial knotweeds (Polygonaceae family) originating from the Himalayas and Asia, with P. greuteriana previously considered a variation of P. microcephala. P. microcephala (e.g., ‘Red Dragon’) is known for variegated foliage and white flower heads, while P. greuteriana is a distinct species in some classifications.
