White Oak (Tex.) 



la Britten and Shafer (North Am. Trees, 328, 1908) have segregated from Querent muehlenlergii Engel- 

 mann a broadleafed flaky barked form under the name Quercus Alemnderi Britton, Alexander's Oak, 

 which is said to have been confused with Quercus muehlsabergii Engelmann. The writer hesitates at this 

 lime to accept this segregate because Engelmann's characterization of the Yellow or Chinquapin Oak 

 includes both the lanceolate form of leaf and the larger, "broadly orate or obovate" form of leaf, a phase 

 of the Chinquapin Oak which, according to Engelmann, "is identical in bark and fruit with the narrow- 

 leafed form." Quercus Alexanderi Britton is said to be distinguished chiefly by its obovate or oblong- 

 ovate leaves and its flaky, scaly gray bark. 



20 In October, 1915, the writer found this tree growing abundantly in New Mexico along the dry rook 

 borders of the water courses named above, this being then the most western station recorded. In Septem- 

 ber, 1921, Harrison Burrall of the Forest Service found this oak in the Lincoln National Forest, still far- 

 ther west, in Lincoln County, vicinity of Pine Lodge in Arroyo Seco. Further exploration doubtless 

 will discover that the tree is quite generally represented in these and other mountains of the region.
