Trying to identify these two fairly common species of grass.
The location is South East Texas. Both occur in fairly wet areas and seem to have sprung up with the heavy rains.
Thanks for the help,

I can get you to genus. First one looks like one of several potential Dicantheliums common in East Texas woods.

Second one is a Juncus (rush). J. rotundus maybe??? but I'm taxing my memory cells.

I would need to look in a plant book to get close on species. You can also run through the pictures they have on A&M's SM Tracy Herbariam online database.

The bottom is a sedge (sedges have edges, not all plants with edges are sedges)

can you pick some of the top one and lay it flat on a plain background

Thanks!
I knew this board would deliver.

I'll inspect a little closer to see if the bottom plant has a triangle or round stem.

Top one looks like Uniola (chasmanthium). Need a shot of the seed head.

Top looks like signal grass. Bottom is green kyllinga

Google "USDA Plants Juncus scirpoides"
The USDA plant database includes pictures of most common native plants.
I'm pretty sure that is it (second plant).

The grass (first pic) may be "Dicanthelium dichotomum", but it is tough to tell without pics of seed head.
Some books and online sources call the genus Panicum versus Dicanthelium.
The taxonomists can't agree which is the correct genus for this group of grasses.
