Hooghly Today : might be Hygrophila polysperma (Roxb.) T. Anders. :  4 images. 3 posts by 2 authors.

This seems to be the one, described and illustrated in –
This plant is Hygrophila polysperma (Roxb.) T.Anderson. Besides other features the glabrous capsule with pubescent tip can clearly be seen in image no. DSCN7837.
And this is the same plant as in – efi thread, though in different stage of growth. This is more mature stage. More the waterline recedes the spikes of this plant elongate more, and the leaves, i think, reduce, both in number and size.
The following links might help to determine the species :-

One more time I share this, to show how the species looks at different stages of growth.

ACANTHACEAE FORTNIGHT:: For id from Kaithal::NS MARCH 34/34 : 8 posts by 5 authors. Attachments (4)
This small herb with minute flowers was recorded from my village, usually comes with rice crop (after rains)..

I am yet to know the name, the tentative id for me is any Phaulopsis sp., please advise..


Only species of Phaulopsis so far in efi is Phaulopsis imbricata


Please check the probability of Hygrophila polysperma (Roxb.) T. Anders.


Yes agree with … Looks like Hygrophila polysperma.


There is only one Phaylopsis in FBI, P. parviflora Willd., the correct name of the genus is Phaulopsis (ref. Tropicos) though.

This is plant is not Phaulopsis parviflora Willd.


Thank you very much … for id conclusion..I will check the local floras for further information…!!

Acanthaceae …Hygrophila sp. ?? : 2 posts by 2 authors. Attachments (12)
Presenting for identification and deliberation … is of opinion it is probably Hygrophila polysperma (on fb).
An auatic herbaceous plant from Surat, Gujarat, seen today (28.11.19) around 0930 hrs in morning.
Habitat a vacant plot, was waterlogged. Other plants around were Alternanthera sessilis, Hygrophila auriculata, some grasses, Stemodia viscosa, Ammannia baccifera.
Habit is prostrate, terminal part of stem or branches erect.
Flower very small…size evident compared to fingers in frames.

To me also appears close to Hygrophila polysperma (Roxb.) T.Anderson as per images and details herein and as per comparative images at Hygrophila‎

This herb is from Pench Tiger Reserve
Photo taken on 28-12-07
This forms like a carpet in wet area during winter

Please id this plant


My guess is Striga sp.


This looks more like a member of Acanthaceae not striga


Lepidagathis cuspidata ??


No. It looks different as per Lepidagathis cuspidata


Thanks a lot … for resurfacing. I think this plant is¬†Hygrophila polysperma (Roxb.) T.Anderson…‚Ķ.

Check for Asystasia mysorensis...looks similar to the one posted by me
earlier from Nasik and identified as above.
Just a guess.


Not agree with Asystasia mysorensis

sharing closeup of flower


Just a wild guess

Looks like Limnophilla rugosa (Scrophulariaceae) but it is a aromatic plants your plants have any aroma pls check sir !


I don’t remember about any aroma. I think Aroma was not there in this herb


Yes, there was no aroma, as we shot this herb together..from the same place..


Acanthaceae, probably a member of Justicia


Lepidagathis


I think it is Hygrophila polysperma as per images and details herein.




 

Justicia sp? SN9121
3 images.
wild herb near Korba


Details are not clear.

May I request you to pl. post high resolution images of 1st two images.


2 images.


Pl. check comparative images at Lythraceae


Maybe some Rotala species as per comparative images herein.

It is close to Hygrophila polysperma (Roxb.) T.Anderson of our comparative images.
