Polygonaceae Fortnight- Polygonum pleibium from Kaithal:: NS May 32

[Nidhan Singh]

Dear All,

These pics were recorded from Kaithal, I hope they also belong to Polygonum pleibium, this form has few flowers at nodes; internodes and leaves longer..

Please give your opinion..

Thanks for this post Nidhan Sir! Your doubts are very genuine.

Stamens are generally 5 in P. plebeium...here I can clearly see 8 stamens, distinctly pedicellate flowers exserted from ochrea and equal size tepals. Hence I think your plant is Polygonum effusum Meisn. The plant was once considered a variety of P. plebeium (as you also guessed) but later separated.

You can find the details here:

Thanks again for the post.

Regards,

Ritesh.
