Korycarpus Zea ; Lag., Gen. and Sp. Nov, 4. 1816. The only species described 
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 
festucoides Raf. (fig. 20), is 
found in rich woods through 
the eastern United States. It is 
of little importance as a forage 
gfrass.
