Botanical description (B.FL, vii, 579). A common grass, very 

 variable in habit, usually erect or decumbent; 1 to 2 feet high or rather 

 more, with flat, rather flaccid leaves, but sometimes smaller, with 

 convolute or fine, almost filiform, leaves. 



Panicles usually very loose and spreading when fully out, 6 inches to 1 foot long, 

 with long capillary divided branches in distant whorls or clusters. 



Spikelets very numerous. 



Outer glumes narrow, very pointed, 1 to 1^ lines long, or in some varieties, nearly 

 2 lines. 



Flowering glume about half as long, thin and almost hyaline, broad, enveloping the 

 flower, truncate, or very shortly and unequally tw r o- or four-toothed, sprinkled 

 or densely covered with hairs on the back, rarely almost glabrous, surrounded 

 by the hairs of the rhachis, with a fine twisted awn attached about the middle 

 of the back. 



Palea very narrow. 



Rhachis produced into a bristle, usually very short and ciliate with a few long hairs. 



Botanical notes. Normally with a very hairy flowering glume. Var. 

 l&viglumis with flowering glume nearly glabrous, except marginal cilia. 

 Lake George, N.S.W., and in Victoria. 



Value as a fodder. A very abundant grass in the cooler parts o 

 the year, disappearing during the hot summer months. It produces 

 large quantities of excellent pasture. As the seed ripens the panicles 

 break off the stalk and blow about, frequently accumulating in large 

 quantities against obstacles. Here follow a Victorian and a New 

 Zealand account of the grass : 



" It is the first grass to spring up after summer rains, and keeps 

 up a supply of nutritive herbage. During winter it seeds freely. I 

 onsider it a useful winter grass. When summer comes it dries up, 

 making room for other sorts." (Bacchus.) 



"Often forming a prominent part of the pasture on dry, stony, or 

 sandy soils. It is valuable as a sheep-grass in such places, probably 

 proving perennial when prevented by grazing from ripening its seed, 

 the permanence of such grasses often depending on their capability to 

 stole or form off-sets or branches at the roots before flowering and
