64 PASTURE PLANTS AND PASTURES OF N.Z. 



flowers are small, green, and crowded together in a 

 rounded head a good deal like that of the native Piri 

 Piri or bidi-bid. 



Sheep's Burnet has been recommended for inclusion in 

 pastures, because it provides a certain amount of palatable 

 feed, and because it has a deep penetrating tap-root that 

 will break up the sub-soil. The penetrating power of its 

 root is, hovewer, not great, and stiff clay pans will turn the 

 root so that it runs along the surface of the pan instead of 

 going through it. In this case Burnet has nothing left to 

 recommend it. 



The seed is large and four winged ; each so called ' ' seed " 

 contains several seeds, so that its germination exceeds 100 

 per cent. Its cost is about Is. 3d. per pound.
