TRIANDRTA. DIGYNIA. Agrostls. 12? 



Leers 4. Q-FI. dan. l6l, (exact as to the flower, but seems a 



starred specimen.) 



About \ a yard high ; branching from the root. Straw and 

 Root-leaves smooth. Stem-leaves roughish. Sheath-scale very 

 short* cloven* Panicle 3 to 5 inches long, either purple or 

 white. Branches 1 to if inch. Calyx valves unequal in the 

 flowering but equal in the seeding state ; the outer only serrulated 

 on the upper half; the inner smooth. BIoss. inner valve very mi- 

 nute, but y the length, and | the breadth of the outer. Awu 

 bent, tw r ice as long as the blossom, and fixed just beneath its , 

 middle. 



This is not ihtAgr. cantnaoll Linn, nor of Huds. though 

 that trivial name is applied to it because it is the name of Leers 

 and Fl. dan. and as the Agr. canina of Linn, is now referred to 

 another species, no confusion can arise from the use of this name. 

 The specimens now before me perfectly accord with the fig. of 

 Leers as well as with his description, but they do not shew the 

 brown knot upon the awn mentioned by him, but he observes 

 that this does not appear until the flower is old.

The panicle and its branches of a fine red purple, but as it 

 ripens the florets change to yellow brown, and both the awn and
