Looks like Polygonaceae to me.


Aconogonum campanulatum??


Are there any other Indian varieties of Aconogonum …??


Aconogonon campanulatum (Hook. f.) H. Hara (=Persicaria campanulata (Hook. f.) Ronse Decre.) is supposed to have a branched panicled inflorescence.
This is Persicaria chinensis (L.) H. Gross which is characterized by terminal or axillary capitate inflorescence.

Flower in heads. No involucral leaf at base. Petioles not winged. (All this goes in favour of P. Nepalensis)
Stems unarmed nut trigonous…(Hopefully) This is Persicaria auriculata S.K.Dixit, Datta and Roy.
One synonym is Pesicaria chinensis.


Many thanks … for clarifying the differences among P. chinensis and P. nepalensis.
Another species close to P. chinensis is P. dichotoma (which has grooved stem, and minute prickles, the inflorescence as the name suggests is branching, the flower clusters relatively far-spaced).
Present status at The Plants List, Persicaria auriculata S.K. Dixit et al. is a synonym of Polygonum praetermissum Hook. f. …
And Persicaria chinensis (L.) H. Gross is separately treated … The Plants List.


P. nepalensis I hope is a much smaller delicate plant with much smaller infl and distinctly winged petiole. This plant has the habit of P. chinensis. One should always look for some matured flowers in which perianth becomes larger fleshy and blue-black in fruit.

And yes the two P. auriculata (now treated as synonym as mentioned by …) and P. chinensis are very distinct and not synonyms.


Agree with … opinion. This looks like P. chinensis to me too.

in this dense growth, difficult to see leaves that go with the flowers. nice flowers


Yes, the leaves are all mixed up, or rather hidden, overlapped by other plants’.
The flowers of this genus are similar among its species. As such I have no clear feature to tell. But the sight reminds of P. chinensis.
There is light green, seemingly amplexicaule leaf (or bract) – that helps me, may help others to validate OR comment otherwise.

Climber from Uttarakhand 08: ID Requested : 6 posts by 4 authors. Attachments (3).

Please heelp in id this plant.
: Climber, much branched
: Leaves and young twigs with sheath.
: ca. 1800 m asl.

Polygonum chinense, perhaps.


By description in flora,..P. chinesis is a herb, up to 1 m tall, but the present study is a climber ca. 4 m long. However, inflorescence and fruiting pattern matching with P. chinensis. I also check it for P. convolvulus (Climber), but differing in spike like inflorescence.


just because something seems to be a climber and growing tall does not negate the its identity, to my mind
I have a green chilli plant right now in my kitchen that’s almost dying but all thru the year it grew as a straggly almost three foot long “vining” plant
its just that the seed (from the same one red chilli) got stuck at an edge in a small pot and that seedling just struggled and grew taller by the minute… flowered once , never set fruit… it spent all its nutrition and energy into growing tall; while rest of the seeds’ seedlings grew to normal in bigger pots on the same window sill..same light same water same food.. just a different foothold…

Take home message to me has been …

if all else fits, it must get the label of its id…

Same as in cancer tumors that grow into mass and stay that way while in somebody else may spread and spread..we have a ” seed and soil” theory for cancer growth … mother nature being what it is must play the same design in growth in all biological systems , up to a point…
is my two cents worth.

thanks…

Post script:
In Shantiniketan on the grounds of Gurudev’s homestead and other huts/homes there is a vining tree, I want to say mango but it may be something else, I have forgotten’ but its a normally a nice large tree, erect stout.. … but there in that garden its “vining” , one of the brothers or nephews noticed it early on and gave such support as to let it vine…. after almost nearly 100 years its still in that form..
its still present and growing and the guides point it out proudly…
so it happens, has happened…

Cultivated plant seen last month (July’16) in Nairobi.

Looks like some Persicaria Species from the Knotweed family.


Yes! Persicaria for sure. Can not confirm the species, as I don’t know much about the flora of Kenya.


Thanks for your feedback.
Although seen in Kenya, this was a cultivated, garden plant.
Hope to get the Species.


This looks close to Persicaria campanulata ‘Southcombe White’.
Just a guess.

May be. appears close as per images at
Binnyplants


Thanks a lot … To me it is very close to the last link provided by you as the flowers were white. Hope … has a look.
