Thanks Anurag for this post.

Nice pictures, Anurag!
The number of stamens here (4?) makes me think that this is not Hygrophila polysperma (2 stamens) that I suggested earlier in Dinesh ji's post. 

I look forward to know its ID.

Many thanks Vijayasankar ji for this clarification.

Anurag Ji, Dinesh Ji, Vijayasankar Ji,

The flower form doesn't look like that of other Hygrophila we have seen so far. Here corolla is not markedly 2 lipped. Corolla tube is rather cylindric, marked with stripes. To me it looks more like Ebermaiera species than anything else. Bracts and bracteoles also conform.

I think this maybe Ebermaiera glauca Nees. Please check the probability. Please also note anthers in the illustration and the submitted picture (DSC_04061).

Thank you

Regards

I agree with you sir.

While going through my photos from the same trip, I found another set of photos from another place (Hebri) we had been to.

I am attaching close ups of that set here. They show the characters much better than in the original uploads.

Please also see http://florakarnataka.ces.iisc.ernet.in/hjcb2/img/pdf/Staurogyne%20glauca/page_348.pdf.jpg from the Flora of Udupi. Hebri, the place where this one was clicked lies in the Udupi district and hence the distribution also matches.

Thank you.

Thank you very much Anurag Ji, I had some hesitations regarding the loops of lateral veins at margin, but I think your picture DSC_0406 satisfies Wight illustration.

Please check my species which I think is Ebermaiera glutinosa Wall., I have two sets of pictures and this species grows on the margin of paddy field -

Thank you once again.

As far as I can find, there are only two species of Staurogyne/Ebermaiera found in Karnataka. Gamble too lists two species in the flora of Madras Presidency. Out of the two species that fall under them, S. zeylanica can be ruled out (http://florakarnataka.ces.iisc.ernet.in/hjcb2/herbsheet.php?id=48&cat=1) on the basis of lack of viscid structures which are very evident in the photos clicked by me and Dinesh sir which leaves S. glauca (http://florakarnataka.ces.iisc.ernet.in/hjcb2/img/pdf/Staurogyne%20glauca/page_348.pdf.jpg). Both names are unresolved according to The Plant List.

At the very least, I think we can leave it at Staurogyne sp./Ebermaiera sp.

Thank you very much for your efforts sir. In this process, I have learnt about a few more species of plants!

Anurag Ji,

I have doubt over the pictures in the link you have provided. A couple of pics look more like Lepidagathis to me.

Thank you

[Anurag Sharma]

Thank you sir. Yes, there do seem to be certain mistakes in the live specimen photographs on the portal.

[surajit koley]

Yes Anurag Ji, I think so.

Thank you
