In Edgbaston park, near Birmingham. Withering. At Svvains- 

 thorpe, near Norwich. Mr. Stone. In Angusshire and Fifeshire, 

 Messrs. Don. Hooker. 



Perennial. July. 



Like the preceding in habit, and in general structure j but our spe- 

 cimens are much more luxuriant. Spike about 3 inches long, 

 conspicuous for the orange colour of the anthers, which are still 

 more peculiar on account of their short roundish figure. The 

 shortness of the awns may be a variable circumstance. The sug- 

 gestion of Dr. Withering first led me to propose this as a species, 

 and 1 still wish to leave it for more accurate examination, though 

 Professor Hooker is of a different opinion. I hope not to be 

 thought precipitate or dogmatical, which faults I have had ex- 

 perience enough to wish, at least, to avoid.
