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.

This is possibly Monocharia hastata.

Monochoria vaginalis.
pls validate

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.
vaginalis
is supposed to have cordate base and blue flowers!! This is of course a semi aquatic plant.


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
and shape of the leaves there. Many pics are available. I assume there is a Flora of Haryana available.
You never know, this could be a new species for state!


There is another taxa which is not accepted by Kew but I believe it to be a distinct plant:
Monochoria vaginalis var. plantaginea (Roxb.) Solms
Though I am not so sure yet.


Two diff species are reported from Haryana vaginalis and hastata.
Key indicate vaginalis as
leaves base cordate or truncate- m. vaginalis
hastate or sagittate- 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
of M. vaginalis. Monochoria hastata has one more variety, M. hastata var. elata.


By the way according to your key, your leaves are not truncate!!
neither they are hastate, nor cordate or sagittate. Thats why I had doubts.
Anyways….


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
of some prominent characters differentiate it into two distinct varieties or may be species too and you will get a very good taxonomic publication that way too.


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
Derekliew


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

Maybe … is correct, it might be Pontederia vaginalis (Monochoria vaginalis var. plantaginea of “Bengal Plants”).

ID request- 280621AS03 – maybe Alisma plantago- aquatica:

Could you please help in identifying this plant?
Date: 26/02/21
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 …,
its Pontederia vaginalis,


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.
