Thanks, Garg ji.

I went through both pages in eFI site ... Alternanthera ficoidea and Alternanthera sessilis ... I find that the leaves are variable in both pages, both are sessile.

Please let me know of some "visual" characteristic in the posted plant that suggests A. sessilis, so that I can look for it in my observations before upload.

Regards.

Pl. check the pubscence of the leaves and nature of the flowers and its head closely.

OK, thanks, Garg ji.

Will revise to A. ficoidea.

More of my Alternanthera observations will get uploaded in due course, and maybe I will keep fumbling; I do not seem to get familiar with this genus :)

Regards.

Yes Dinesh ji the two species are very distinct, A sessilis is a plant of wet places, softer stems and leaves latter often gradually narrowed and obtuse and flowers in dense nearly globose to oblong cluster without sharply projecting bracts. A. ficoides on the other hand prefers exposed habitats leaves and stems are stiffer, leaves often prominently narrowed towards base and flowers in few flowered clusters, with distinctly projecting bracts and perianth.

Please see my post  of Al sessilis  https://groups.google.com/g/indiantreepix/c/fWD55JxZ2u8/m/R85CiafwRH8J

And A. ficoidea        https://groups.google.com/g/indiantreepix/c/K6OwDVi8X7I/m/vPHHXw69Gm4J

And a simple key to genus     https://groups.google.com/g/indiantreepix/c/6LYsGV33bi8/m/52EhYfhsR5IJ

Thanks very much, Gurcharan ji, for the clarity and simple keys.

I hope my further uploads will be with proper IDs.

Regards.
