Keys as per Flora of China and FoC illustration;
The leaves are 15-20 cm long, hastate; the flowers are on long pedicels. In M. vaginalis the leaves are 10 cm, ovate-cordate and flowers are sub-spicate.
Besides flowers, perianth segments of withered flowers are seen twisted around the fruit in a cork screw manner. This is another character of M. hastata compared to M. vaginalis.

Yes Monochoria vaginalis—Pontederiaceae. I had grown this plant in the periphery of a pond inhabiting yellow lotus in the Herbal Garden of DR.Y S Parmar University of Horticulture & Forestry, Nauni, Solan, HP. It has medicinal properties.

It is my pleasure to share few images of Eichhornia azurea (Pontederiaceae)
The plant is rooted to the soil, found in shallow water, as against E.crassipes that floats.
Sighting: Tumkur, Karnataka, about 800 msl
This does not appear to be Eichhornia azurea as per
It should be Pontederia vaginalis as per images and details herein.

hopefully it was growing near some water if i am not wrong
Yes … Near a small water body around rice fields
Is there any other Monochoria available in your area. Because I have doubts on this identity!! Leaves are too narrow, flowers are white. M.
Flowers are blue, i dont know why camera could not catch color properly. These photos were taken today only
Leaves are also different. I have seen this plant many times. Never seen with such leaves. You can google this plant and see the colour
There is another taxa which is not accepted by Kew but I believe it to be a distinct plant:
Two diff species are reported from Haryana vaginalis and hastata.
Monochoria vaginalis var. plantaginea (Roxb.) Solms also given as synonym of M vaginalis in flora of Haryana
I think two species are reported from whole of India but both of them have varieties. All varieties of Monochoria is considered as synonym
By the way according to your key, your leaves are not truncate!!
Agreed … I will try to visit that place again in one or two days to observe more plants for leaf morphology. If it comes out to be a new ssp or variety, then it will be a new record from Haryana
So now you know sir why I had been so against the id. You may try to find both of them, may be vaginalis and plantaginea, and on the basis
Just in case you come to the conclusion that your id is correct. Then also you can write an article on MORPHOLOGICAL AND ANATOMICAL VARIATION IN LEAVES OF MONOCHORIA VAGINALIS FROM HARYANA.
Really great variation if accept it as single taxon. Our Monochoria vaginalis in Kashmir is more like this one
Yes, this is for sure M. vaginalis. Thanks for sharing….
Thanks for Sharing … I will try to find out the plant somewhere else also
Just a clarification. This is not my plant. Just a link from the net, a plant similar to found growing in Kashmir.
Yes, Pontederia vaginalis

Is it any species of Sagittaria ?
Looks different from comparative images at Pontederiaceae and Sagittaria
Maybe … is correct, it might be Pontederia vaginalis (Monochoria vaginalis var. plantaginea of “Bengal Plants”).
Trapa natans var bispinosa
ID request- 280621AS03 – maybe Alisma plantago- aquatica:
Could you please help in identifying this plant?
Location- Ghoghri Village, near Satpura National Park, altitude- 325 m
Found in the wild, in a stream. It is an emergent aquatic plant
No flower observed at this time.
I don’t think it is matching !
You’re right …,
Thanks …, I think so too! 🙂
Is there any chance for Pontederia crassipes Mart. as per comparative images at Pontederia ?
No, I don’t think it would be Pontederia Crassipes as it does not have the bulbous buoyant stem. The specimen was firmly rooted in soil and the leaves seemed to be more cordate than the images on the website of crassipes.
Help me to identify this flowering plant: 2 images.
