identifying wild p. arundinacae (pics)

[concombres]

I've seen alot of what looks like phLaris arundinacae growing in & around my yard recently but im unsure how to tell the difference between it & its look alikes. I know for sure what im seeing is not common reed because theres plenty of that nearby too & the seed heads are different.
However, im having trouble figuring out if what im seeing is phalaris or dactylis glomerata.
Its a little different than some pics ive seen on the net mainly because its fairly small specimens but i figured it may just be that they are young. Id like to figure out whether this is phalaris or not. If its not its the right time of year to plant p. Aquatica & do some etractions later.

From the Dutch Wikipedia page on P.Arundinacae:

Allthough P.Arundinacae looks alot like reed, it differs mainly in that reed has only
hairs in the parts shown in the picture(Where 2 leafs split off of the main stem).

Kind of a vague description, but I assume they mean to say P.Arundinacae has more than
just hairs at the part shown in the picture. Perhaps membranes? I've often split reeds
from riverbanks, removing the leaves, to find sometimes hairs there, but other times
I found them to have slimey semi-transparent membranes.

I'm not too sure. Read into it more. help of someone with more Botanical knowledge would help.

As usual I dont have the resource handy, but there is an ID thread here somewhere, I recall that yes phalaris has a seperable membrane there -I guess reed is yes onlu hairs. I know the nexus search function is just there for looks, and wont find any phrase whatsoever, but do try a google search.
Edit :if you pull the leaf blade down,, youll see za membrane there, youll know it when you see it. If its P that is. Best.luck Im starting to develop intdrest inthiz plant. This is the time of year to harvest right?

Go on amazon by a grass identification book. the easiest way is to have the flower structure, probably not this time of year though. also usda plants, this is one of the best resources if your in the states. also a google image search.....trip to library and get some field guides there........

as a biologist I can tell you not all specimens will show perfect characteristics. Looking at the i.d. guide linked here i see almost no Phalaris on the first page.....theres brome grass(pick up a leaf and look threw it....will be a w or a v shape in the leaf......boom brome grass species....easy id. Foxtails have one solid column of tightly held florets.

anyways, many species of grass have hairs in the membranes or whatever. to tell the foxtails apart you go by the length of these hairs. But I have seen foxtails with no hairs!!!!! when there should have been, good thing it was in flower, or I would have mis-identified it, if I could have at all.

the first two books I have used and are great. It does takes a while to learn the terms, and figure out how to use them. But if I were to try to identify any grass in the USA, these would be where I would start.

No amount of DMT is worth spreading an invasive species. So please be careful when you plant un-native seed.
