Thanks, …  Any other images showing the full plant ?


Seems to be a Persicaria sp.


Koenigia mollis (D.Don) T.M.Schust. & Reveal


How is it different from Rubrivena polystachya ?
What is the difference between this and Koenigia mollis ?


I feel leaf pattern is slightly different!


Koenigia polystachya (Wall ex Meissn.) T. M. Schust. & Reveal: leaf base is subcordate to truncate, perianth not enlarged or fleshy in fruit  (syn: Rubrivena polystachya (Wall. ex Meissn.))
Koenigia mollis (D Don) T. M. Schust. & Reveal: leaf base cuneate, perianth enlarged and  fleshy in fruit (Syn: Polygonum molle D Don; Persicaria mollis (D Don) H Gross)
Leaf base suggests K. mollis
Illustration: Polygonum molle (efloras.org)
