95 Discovered by the writer in November, 1913, on the lower rocky slopes of the Chisos Mountains, 

 Brewster County, southwestern Texas, where it is a small or medium-sized tree. In November, 1920, 

 the writer found a single tree in the Davis Mountains (Olympia Canyon) a few miles north of Fort Davis, 

 while in November, 1921, R. A. Epperson and the writer found this oak growing abundantly in a tributary 

 can .von of Olympia Canyon. Further explorations will doubtless show a wider occurrence of this oak in 

 the Davis Mountains. So far the writer has been unable to find it in the Chinati Mountains. Specimens 

 of this tree sent to C. S. Sargent led him to believe it to be a varietal form of Quercus texana Buckley, and 

 in 1918 it was described as Quercus texana var. chisosensis Sargent. However, a careful field study of this 

 oak convinces the writer that it is specifically distinct from Quercus texana Buckley, and I now propose 

 for it the name Quercus gravesii = Quercus texana var. chisosensis Sargent (Bot. Gaz., LXV, 423, 1918) is 

 honor of Henry S. Graves, formerly Director of the United States Forest Service, who throughout his con- 

 nection with the Federal Government's forest work has been a staunch friend and supporter of dendro- 

 logical investigations.
