From Thomas Rivers 26 April 1867
Summary
Sends a root of a wild oat-grass from California and the root of a variety of barley that came from it. Several varieties of barley, all differing from English varieties, came up in the same bed of oat-grass. "The transmutation of a genus seems almost incredible" but TR has seen so many changes he has ceased to doubt strongly.
