Wild Flower- Sikkim:
sharing the shot of a wild flower from Kyangnosla WLS of Sikkim. Whats the common name of this flower?
Wild Flower for ID : 131011 : 131011 : AK-3:
Pictures taken on the 11th of Sept,11 on way to Gulmarg. Found growing wild near the viewpoint on the way up the mountain. Persicaria?
VoF Week :: DV :: 01 AUG 12 – 1209 :: terminal spiked herb along Govind Ghat – Ghangaria trail:
1 AUG 12 Govind Ghat – Ghangaria trail … about 7800 ft Habitat: mountain slope Many thanks … but a query surfaces in my mind
I am wondering whether the plant in link 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.
VoF Week: Persicaria amplexicaulis along “Govindghat – Ghangaria Trail”.: I wish there was a photograph showing leaves.
VoF Week: Polygonum amplexicaule from way to Valley: Yes … Very good photographs. Very good illustrative photographs. … I appreciate your hunger for studying more and more plants including maximum documentations of the characters.
VoF Week: 16092012 BS-1. Polygonaceae Herb for id from way to Govindghat- Ghangriya: Persicaria amplexicaulis
VOF Week: Persicaria for id from the Trek: 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… 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 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…
