General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
As the name suggests, looks like tufts of lawn grass.
On closer inspection you can see the cylindrical, succulent, green leaves. Almost flat and wide at the base, quickly turning cylindrical. The sparse hairs start along the flat edges thinning out up the leaf.
The flowers are nearly invisible to the eye when walking past, you have to get down on your hands and knees to see them. Like all flowers in the daisy family, they are compound flowers; tiny flowers (called "Florets") inside a larger cluster.
The flowers can be green or white, with some "Florets" in the centre being yellow (We thought these were stamen). Because of the white flowers, we miss-identified some plants as Woolly Heads (Myriocephalus rhizocephalus); but the flowers on these are on stalks.
The only way we can describe the "Petals" of the "Florets" are as: swirls.
The fruits are called "Achenes".
