Madrone-tree. 



*° Arbutus xalapensis Humboldt. Bonpland, and Kunth has long been believed to include both the 

 Mexican and Texas Madronos. The writer has not seen authentic specimens of the Mexican plant. It 

 seems probable that, as indicated by Britten and Shafer (North Am. Trees, 759, 1908), the Mexican tree is 

 specifically distinct from the Texas Madrofio, in which case the correct name for the latter is Arbutus 

 texana Buckley, which has been adopted by Britton and Shafer (1. c).
