" A fine suite of specimens of Oarex acuta given me by Arthur 

 Betinett, Croydon, England, and a study of the species in various foreign 

 herbaria, have enabled me to draw lines of separation between the 

 European plant and the western plants which have been referred to it. 

 0. acutina differs from 0. acuta in the pale color of the plant and its 

 lesser size and thin leaves, habitually smaller spikes, thinner and 

 shorter perigynium, which is much less prominently nerved, and the 

 lighter colored obtuse or muticous scales." {Bailey.) Lewes Eiver,
