Native. Pascual, &c. In giving the altitudinal and 

 zonal range of this species, it is assumed that the vivipa- 

 rous Festuca, so frequent on the mountains of Scotland, 

 is a state of F. ovina, rather than of F. duriuscula. The 

 height of " 1400 or 1450 yards " is intended for the sum- 

 mit of Ben-na-muic-dhu, which attains to 4300 feet, a 

 little more or less.
