* The genus Eriophorum belongs to the natural family of Cype- 

 raceas : it is here placed in company with the proper grasses, because 

 I have observed our English species eaten by cows, oxen, and sheep, 

 in common with those species of proper grasses with which they 

 happen to be combined, while the species of other genera of cype- 

 racea; growing on the spot were rejected ; — not a Botanical 7-eason 

 certainlj', but an Agricultural one, which the learned and indulgent 

 Botanist will here, I hope, excuse.
