II. TRIGYNIA. 
Rumex digynus.—All the species of Rumex are 
boiled and eaten by the Icelanders; 
though only the young shoots of 
acutus are employed. Of the 
Acetosa a beverage is made by the 
common people, by steeping the 
plant in water till all the juice is 
extracted. This drink is kept some 
time; but soon becomes bad and 
putrid in warm weather. 
—— acutus.
