Cyperus helferi is sort of like a rosette plant, while Vallisernia nana produces many runners.

thanks for your reply. Is it safe to assume that both the tips of the C. HElferi and the V. Nanas are different? The CH having a sharper tip and the V. Nanas have a more rounder tip ?
Hi,
found your post once again Other than the tips of the leaves you can look at the leaves themselves. Cyperus is a true grass, so it has a leaf kind of split in two parts by the central nerves which makes kind of keel or edge on the back side of the leaf. Vallisneria has a flat leaves, you can see the veins making some horizontal "rings", but there´s not this kind of crest in the middle of the leaf. I hope this helps
here's a picture of my unknown.. i actually cut it.. so the tip definition is not there.. but based on your description on the leaf.. perhaps we can have a deduction ?
Almost certain it's a Val. Cyperus has much lighter (grass green) leaves while Vals are slightly darker toned and the leaf edges can have an dark outline.
Looks very much like Val That´s not a plant of Cyperaceae family since it doesn´t have the grass-like leaves. Don´t get mistaken by the tips, Cyperus has a REALLY sharp tips, but I didn´t say that Vallisneria has rounded leaves.
But I doubt it is V. nana, since it really has to have a very narrow leaves. With 5-7 mm width I would bet on V. spiralis, but I have no idea what other species of Val are available in your country + the photo is not enough to tell, so I better not guess
I am talking about Vallisneria nana as we know it here in Europe (still quite a rare plant, especially where I live): http://www.tropica.dk/productcard_1.asp?id=056C
That's definitely not Cyperus there; looks more like a species of Vallisneria like the others stated. Here's what my Cyperus looks like.
