 C. acuta is represented in the Linnean Herbarium on sheet No. 28, 

 but another sheet so labelled contains specimens of some other species. 

 According to strict prioi'ity Hudson should be cited for this species,

 In Berkshii'e, C. acuta is a variable species, differing in the relative 

 length of the glumes and the perigynia as well as in other respects. 

 Our forms include var. personata ^Boott, Car. 166, t. 552), Fries, Nov.
