Before experts take care of this post let’s try to learn how to fish!
Can it be any Calamagrostis species?
Can it be any Calamagrostis species?
I couldn’t find any similar looking pic in the net. Moreover, the leaves of various Calamagrostis in FoC are much bigger. So, it seems to be some other grass.
The species is interesting. Unable to narrow down at the moment.
Is the scale showing centimeter or inches? Kindly post a clear close up image of spikelets after manually separating or deflexing it away from the rachis. Also see whether the spikelets are paired and if so whether one is sessile and other is pedicelled or all are similar. Kindly do the dissection of the spikelet and post. Or you can send me a sample of the inflorescence.

It was posted in 2013. … is not responding to this post.
Scale appears to be in Cm.

I regret that I couldn’t reply to you earlier. I regret more that it has been so long since 2013 when I took those pictures.
I found this grass in a ditch alongside a railway track. I am afraid that it won’t be possible for me to return back to the site, or to find there, the concerned species to collect detailed data of this species.
Further, I have deleted most of the plant photographs I stored in my computer. I will search my pen drives to see if I have retained the originals of this one and certainly send you if I find some.
For the time being I can only say that the scale shown in the picture is in centimeter.

I could find only these resized pictures from my saved archives.

Can this species be related to Pseudoraphis, like P. minuta?
Could it be Leersia oryzoides?
It has characters of several general like Pseudoraphis, Hygrorhyza, Hymenachne, etc.
But after a lot of thought, I would rather like to place it in genus Eriochloa, the inflorescence resembling Eriochloa acuminata and spikelets resembling Eriochloa aristata, both of which are American species.
The cup below the spikelet is not clear in the picture though. The stem, node and leaf are more like Eriochloa than the other three genera. The hairs on the spikelets are like that of Eriochloa.
I suggest you could collect it again and try to see the characters in detail to confirm. Probably, It could be a described as a new species.

I love to read your analysis, … I will try my best to follow your suggestion to find this grass once again and obtain as much detailed data as I can.
I thank you very much for taking care of all my uploads, as well as providing me the most valuable feedback on each species. Without your tutorials I would never had dared to record any grass species.
Thank you … for your unique patience and utmost care.
I am sending a few attachments which suggest that the species should be finalised as Pseudoraphis minuta. Since these are dried specimen, it may look a little different from the photographs. As per these and other sheets, this is very common in marshy river banks often found gregariously in some patches. NL Bor in GBCIP states ” An extremely pretty grass with dense panicles of small spikelets which vary in colour from reddish-green to deep purple red” (May be because of the purplish stamens). It also states further “The plants root in mud at the edge of bheels or lakes and send out their culms floating upon water. In Assam it covers areas which can be measured in square yards. Mooney notes on a specimen collected by him by the edge of Sar Lake Cut, Puri. “An aquatic grass growing in water up to 9 in. deep and on damp ground. The water is slightly brackish. The grass tends to grow in small gregarious patches”

I am grateful to you for providing details on this grass species.
I kept it in my mind to revisit the place in order to obtain more details of this species. But, I couldn’t,, because of the suspension of local train service due to complete lock-down since April, this year.
