Dear Sir,
According to Tropicos and Fl. Pakistan, Polygonum tubulosum is a
synonym of Polygonum rottboellioides. A scrutiny of the black and
white photograph and illustration of P. rottboellioides provided in
'The Polygonaceae of Kashmir Himalaya' and in Fl. Pakistan
respectively, I am assuming your plant to be Polygonum rottboellioides
var. tibetica.
The only problem is the number of stamens as appearing in your
photograph 'b' (as small dots) seems to be more than five. P.
rottboellioides has 4-5 stamens only. In that case, I would suggest
this plant as another form of P. plebejum. A high resolution image
would help.
Best regards,
Ritesh.
