Identify this grass?

Question

Identify this grass?

I am doing an assingment for school and I am researching the grwoth of different grasses. First, I dont know anything about grass so could you tell me the types of grass these are. If you know the growth rate or any other imformation could you tell me. The grasses are in my front and neighbours yards on the East Coast of Australia, Sydney. When giving you answer please write it like this.

Grass 1 is this and something.

Grass 2 is this one.

The picture are at http://caleb999.blogspot.com/

they both have the number on them, (Grass 1, Grass 2).

Answer 1

grass 2 is bermuda i'm really sure... it grow around the cracks of cement and it kind of runs instead of growing straight up...grass 1 i'm not to sure it look like little bluestem its hard to tell if you pick some and if it has a purpleish bottom thats what it is...if it has a waxy texture and its bright green it is probably wildrye

Answer 2

grass1 is sperm grass2 is causal  i am 4rm  nigeria

Answer 3

I guess grass 1 is centrosema pubescene and grass 2 is calopogonium mucunoid

Answer 4

called wimbleton grass court 1   court 2

Answer 5

Well, that's a consensus then...

Not convinced by either previous answer.  Not easy without the flowering shoot (nor helped for me by being a British botanist who's hardly ever been past the Isle of Wight...).

Grass 1 could be a ryegrass, but I'd go for perennial ryegrass (Lolium perenne) not annual.  Can't see well enough, but looks creeping to me. Either would have leaves shiny on underside only.  Pretty sure it's not a sedge -- but the clincher would be the shoot pattern.  Sedges always grow with the leaves arranged in three lines -- look down on the shoot, and the leaves make a three-pointed star.  Grasses grow with leaves opposite-alternate in two lines, like the close-up of grass 2 -- they'll lie flat on a flat surface.  Beware rushes though, and other grass-like non-grass plants...  Other possibilities I'm familiar with are a meadow grass (Poa) or one of the larger fescues, such as meadow fescue (Festuca pratensis) -- no doubt lots more Aussie ones.

Grass 2 does look like Cynodon (which we get here as a rare casual).  However, it ought to look greyer, and coarser, with longer leaf-blades.  It (and some others) has a ligule made of hairs not the more usual membrane (the ligule is a bit sticking out where the blade meets the sheath part of the leaf).  The Axonopus looks rather too densely leaved -- but perhaps it can be laxer?

Any chance of flowering or fruiting photos?  You've set yourself a real challenge identifying grasses without them, as you can see from the different views so far...  There are very many species, and probably at least a dozen or so common lawn ones (in UK anyway -- you'll have a mainly different dozen).

Edit -  Ummmm.  Neither Centrosema nor Calopogonium seem to be grasses or anything similar...

Answer 6

Grass number 1 is nutgrass, Cyperus rotundus. Not a grass at all but a sedge.

Grass number 2 is narrow leafed carpet grass, Axonopus affinis.

Answer 7

Hi.

Grass number one is annual rye grass. It has very thin leaves, a bright green and no hair at all.

It is, obviously annual.

Grass number two is Cynodon dactylon.

It's a perennial grass, extremely tough, and it grows parallel to the ground.

Hope it helped.
