by. It is said to have first made its appearance 

 in 1920, and since then has covered an exten- 

 sive area. It shoots up in January and Feb- 

 ruary, and comes into flower in April at the 

 beginning of the dry season, and then dies off 

 as soon as it has fruited. It is a fodder plant 

 of some value, judging by the avidity with which 

 the horses and other stock eat it, and the good 

 condition it keeps them in. 

 Leaves. — It is vigorous enough to kill out most of 

 the other smaller herbs and grasses, and makes 

 a regular carpet.
