168 HORTUS GRAMINEUS WOBUItNENSIS. 



important work, the English Flora, has been given to the 

 public : from which it appears that this grass has been found 

 a native of valleys among the Highlands of Scotland, and I 

 willingly submit to the opinion of the illustrious author, in 

 considering this species distinct from the Holcus Australis. 



Root creeping. Perennial. Native of valleys among the High- 

 lands of Scotland ; and in Germany grows in moist meadows.

The proportional value in which the grass of the seed crop ex- 

 ceeds that at the time of flowering, is as 21 to 17. The grass of 

 the latter-math, and the grass at the time of flowering, are of 

 equal proportional value. 



Though this is one of the earliest flowering grasses, it is tender, 

 and the spring produce of herbage is very inconsiderable, the 

 flowering straws rising up in a manner destitute of leaves. This 

 deficiency of produce is much to be regretted, as the nutritive 

 qualities of the grass are greater than in most of the early spring 

 grasses : it sends forth but a few flower straws, which are of a 

 slender structure, compared to the size of the leaves. This ac-
