Herbarium of unknown

I got this herbarium consisting of grass specimens as a present. The maker of it is unknown. The sheet are labeled with name of specimen, date and place of finding in a beautiful old handwriting. The grasses have left direct prints on the opposite pages.  

Herbarium At Home is a volunteer-based project that aims to catalogue and make available the wealth of data represented by the historical herbarium collections held by universities and museums in Great Britain. Everyone can join and help label (and in return look at the most amazing examples for free).
