In a narrow mountain valley, called Kella^ in Angusshire; G. Dotu 



Near Thurso, Caithness ; Mr. llobert Dick {185^). 1(1. 5. — About 



1 foot hip^h, glabrous. Leaves linear-acuminate. Panicle brownish, 



glossy. Sp'ikekts broadly ovate. Glumes ovate, acute, rather unequal, 



sometimes a little serrate at the point. Florets rather longer than the 



glumes : the outer glumellas are of a firmer texture, scabrous when 



highly magnified, distinctly fringed at the margin, the point sharp, 



but not awned. Ceyitral floret the smallest. Smell resembling that 



of Aiitlioxaiithum odoratum, Don's station has not been verified ; 



but the plant is, we believe, abundant in Caithness. In Iceland it is 



so plentiful as to be used by the people to scent their apartments and 

 clothes,
