42608. Panicum laevifolium Hack. Poaceae. Grass. 



From Johannesburg, Union of South Africa. Presented by Mr. J. Burtt 

 Davy, botanist, Agricultural Supply Association. Received April 25, 191G. 



"An annual hay grass common In wettish lands in our maize belt. This is a 

 remarkably heavy cropper, and if I remember rightly one of my early investi- 

 gations gave a cutting of about 5 tons of hay to the acre, but I have not my 

 original notes, which have been lost somewhere in the Department of Agri- 

 culture. This grass seems to thrive best on alluvial deposits, but it is also 

 found on almost any kind of soil where water is apt to stand during rains. 

 Animals are extremely fond of it, and we consider it one of our best native 

 grasses. As compared with teff (Eragrostis abyssinica) , the principal drawback 

 of Panicum laevifolium is the unevenness in maturity of its seeds, whereas teff 

 matures very evenly, owing to the fact that the first-ripened seeds do not fall 

 off easily, as is the case with P. laevifolium. However, in spite of this 

 drawback I think this grass may meet the needs of some particular locality in 

 the South where the rainfall is erratic and apt to come after long intervals of 

 drought." (Davy.)
