 lanceolate, acuminate; callus pungent, 1^ line long, villous ; awn yellowish, 2 to 3

In the report of the Cape Botanist for 1864, this grass is alluded to, and is said 

 to be known as " Roode Zaad Gras," and Mr. Ella, of Queenstown district, says of it : 

 " Said to be a good sound pasture, standing and eatable when all others have been 

 blown into dust, it does not stand frost, nor does it shoot early in spring, nor does 

 it grow readily without moisture, but from its permanency when once matured it 

 may be said to be the most important of the district."
