A grass of large growth and very leafy, affording a rich and nutritious food for animals ; in some cases it forms 

 large mounds or tussacks, not unbke those of the Dactylis caspitosa of the Falkland Islands (the Tussack grass), but 

 smaller ; with, however, a similarly luxuriant habit. In size it varies extremely, froni several feet to a few inches in 

 height, and from a robust to rather a slender habit ; it is only indeed when growing in large masses that it assumes 

 a characteristic appearance, in this respect further resembling the celebrated grass above mentioned. The small 

 specimen from McQuarrie's Island especially, I should have been inclined to regard as another species, had the plant 

 not appeared in a similarly starved state in Campbell's Island. In the large cidms the ample sheaths of the old 

 leaves conceal the compressed form and distichous insertion of the leaves, which are very marked in the younger 

 ones, and in certain states as conspicuous as in small states of the Tussack grass itself. 



It is with much hesitation that I refer this to Festuca, for I know no species of that genus with a similarly leafy 

 and soft habit, or with cgmpressed culms and distichous leaves, the only one indeed which appears to bear any 

 resemblance to it is the jP. Bonax, Lowe, a Madeira plant, and that merely in being of a large size and having a 

 somewhat similar large and branched panicle. The want of the arista alone at the apex of the lower palea restrains 

 me from placing it with what is certainly its nearest ally, the true Tussack Grass.
