Polygonum amplexicaule (probably var. sinense if the infl. is
branched).

Have we heard of Polygonaceae with more than five stamens?. I am looking at polypetalous members. Perhaps seen but not able to recall.

Dear Sir,

The number of stamens in Polygonum is not limited to 5 only.

A/C to FBI, the number of stamens in:

Polygonum Sect. Avicularia: 3-8
Polygonum sect. Persicaria: 4-8
Polygonum sect. Bistorta: 4-10
Polygonum sect. Cephalophilon: 6-8
Polygonum sect Echinocaulon: 5-8

So, I suppose this plant to be as Polygonum amplexicaule (syn:
Bistorta amplexicaule).

P. amplexicaule var. speciosum is very common in E. & W. Himalayas
having dark pink perinath.

Best regards,
Ritesh.

Ritesh ji

Thanks for information.

Magnifications sometimes confuse, was confused about the plant I have seen so many times. Incidentaly I did not see leaves earlier.

You are right, it is Polygonum amplexicaule. Here are my photographs from Manali.

I think this has to be  (AS per GRIN)
Bistorta amplexicaulis var. alba or var.amplexicaulis syn.Polygonum amplexicaule
White Mountain Fleeceflower
Dr Phadke

[Gurcharan Singh]

Rather if we look up eFlora of China it should be B. amplexicaulis ssp. sinensis (lax inflorescence, tepals narrow).

Gurcharan ji,
Flora of China mentions Polygonum amplexicaule var. sinense (Syn.:
Bistorta amplexicauis subsp. sinensis),
however, the flowers are supposed to be red. Nowhere does the
description mention white flowers.
Bistorta amplexicaulis var. amplexicaulis is supposed to have white
to pinkish white flowers. Cannot verify other aspects, as no picture
or sketch is available.
