Persicaria amplexicaulis (D.Don) Ronse Decr

Many thanks … but a query surfaces in my mind
I am wondering whether the plant in 
is same as the posted plant here.

Yes … You find this colour variation common.

It was earlier called Bistorta amplexicaulis var. alba however that is now treated as a synonym of Persicaria amplexicaulis.

can this be a sp of Persicaria

Persicaria amplexicaulis



VOF Week: Persicaria for id from the Trek:
This was shot from the Gobind Ghat-Gobind Dham Trek…I hope to get id for this Persicaria sp….

It is Persicaria amplexicaulis (D.Don) Ronse Decr

Thanks … I was almost sure this being P. amplexicaulis…the only doubtful thing is the attached plant which is also identified as P. amplexicaul(e)is….hope to get clarifications

yes it is also same

now i am confused… is perscicaria and polgonum the same?

Treatments of Polygonum and related genera (subfamily Polygonoideae) those by Haraldson and Ronse Decraene & Akeroyd, have segregated species of Polygonum in the broad sense adopted into two separate tribes, Polygoneae and Persicarieae. The remainder of Polygonum in the broad sense is generally assigned to Persicaria (or a varying number of segregate genera, such as Aconogonon and Bistorta) which, with Antenoron and Koenigia, comprises the tribe Persicarieae.
Characters for segregation of Two species:
Polygonum: . Flowers axillary, solitary or in small clusters, sometimes forming lax leafy spikes. Perianth (4- or)5-parted, not enlarged in fruit. Stamens 5-8, reduced in number in outer whorl; filaments, especially the inner, strongly dilated at base.
Persicaria: Inflorescence spicate, spikes usually several. Tepals fused for about 1/3 their length. Nectaries free, globular. Styles 1, bifid or trifid.
… can be more useful for clarification.

thanks for thew science… but i was referring to the conversation you and … were having…
botanists perhaps understand the shorthand communication.. what is the same? as you said it?
i dont understand this … read the conversation you were having between the two of you and tell me what /which is which…
we have many many non botanists who follow these very carefully…
botanists /experts need to be explicit… and not use short hand conversation…

Perhaps of your interest (or you may already know) this species is important medicinal plant and also popular herbal tea.
Yes this plant produces bith white, pink to almost red flowers. … in this thread uploaded plant with white flowers, identified as Percaria amplexicaulis (Polygonum amplexicaule). Since … had earlier uploaded a red flowered plant also identified as P. amplexicaule, so he had some confusion, and uploaded it again. To which … replied “yes it is also same”.
I hope it clarifies any confusion.

no it does not
the pink flowered one is labelled polygonum, on the slides

There are two different aspects of taxonomy
1. identifying the plant correctly: you identify a plant as tamatar, tomato, Lycopersicon lycopersicum, Lycopersicon esculentum or Solanum lycopersicum,………it is a correct identification for our common plant
2. Correct nomenclature: what should be the correct scientific name used when communicating. The herbarium sheets world over will bear the scientific name applicable when the sheet was prepared, and very rarely these labels are changed. Similarly many of have thousands of photographs with label that will bear the name which we knew (depending on the book we have used) at the time of identification. In fact all my photographs of this species will have label Polygonum amplexicaule. Only when I upload these photos, I will mention the current accepted name Persicaria amplexicaulis in the text, the photograph label be same old Polygonum.
Why I mentioned tomato is because this plant Originally names Solanum lycopersicon, underwent lot of name changes when transferred to genus Lycopersicon (Lycopersicon lycopersicon to Lycopersicon lycopersicum because former is a tautonym—a repeated name not accepted in botany although accepted in Zoology). The experts had to sit in 1981 and declare Lycopersicon esculentum as nomina conservanda. We used this as correct name for nearly two decades till it was thought that tomato is a part of Solanum, and we started using Solanum lycopersicon as correct name (See GRIN). 2010 onwards we are again finding The Plant List using Lycopersicon esculentum as the correct name.

Nice explanation with apt example …
Since tomato is the example here, I thought the article in this link is relevant here.
The introduction part provides some background information on the nomenclature of tomato and its allied taxa.

Thanks … and … this opened up a gate… found that Polygonum sp many of its members are now re-classified ad Persicaria…. fine, accept that… so end to this case and … thanks for the paper… dont understand it too well in details, only the gist, that’s ok, am not a botanist, let alone a taxonomist, nitty gritty details go well over my head just now…. will persevere though…
But if we in cancer word did this at every conference and changed names at the drop of a hat…
we would be no where and neither would the poor oncologist-patient-radiologist-radiotherapist combo!!! god save us from these nitpicking…
since persicaria means like a peach tree leaf … if taxonomy really wanted to progress… they should get away from these medieval names that do not make sense and get to be modern… when did one see a tomato plant leaf look like a peachtree leaf??? tell me that!!!!
but then I am being funny, difficult, raising question to which you have no answers yet.. so be it… and this question is rhetorical and non-sense at best , in the era of current state of plant list+ kew + mobot mindset….
science progresses slowly…
