Dear Mr. Deane:— 
I have looked over the specimen of Festuca you sent 
down and I think it is correctly named (Fe stuca ovina var. jurius - 
cula ). I have compared it with European specimens and have 
looked up the descriptions in Hackel’s monograph of the European 
species of Festuca and also Asoherson and Graebner’s Synopsis of 
Middle European plants. Your plant is the subvariety trachyphylla 
Hack, which differs from the typical form of duriuscula in having 
scabrous blades. I am wondering what reason you have for doubting 
it to be F. duriuscula . 
Very truly yours 
Systematic Agrostologist
