EHRHARTA COLENSOI. 



This grass lias only been found on the Ruahine and Tararua Mountains, in the 

 Xorth Island ; it grows in flat tufts or tussacs on the open land above the limits 

 of bush. Very little is known of its value as a pasture grass, its limited distribu- 

 tion preventing opportunities for observation or experiment as to its fitness for 

 cultivation at lower levels. From the known fact, however, that many of these 

 alpine grasses are very succulent and fattening, and much relished by sheep during 

 the summer months, this species may prove valuable when the extensive sub-alpine 

 country in the neighbourhood of these mountains is opened up for settlement.
