Korycarpus Zea ; Lag., Gen. and Sp. Nov. 4. 1816. The only species described 

 is K. arundinaceus Zea, which is the same as Diarina festucoides. Lagasca cites 



the reference "Ac. Matr. 1806," but 

 there seems to be no evidence that the 

 name Korycarpus was published earlier 

 than 1816. 



Our single species, Diarina 

 f&stucoides Raf. (fig. 20), is 

 found in rich woods through 

 the eastern United States. It is 

 of little importance as a forage 

 grass.
