abounds in Florida, where it may be found on nearly every kind 
of tree. We know of one plant growing on a low Prunus 
dosa along the Rio Grande. Dr. George Engelmann” says of var. 
macrophyllum that it was found on soft woods, the Ash, Willow, 
oplar, Sycamore and Sapindus, along the Gila and Bonita riv- 
ers; and of var. villosum, that it was found on hard woods, prin- 
¢eipally Oaks, in Oregon, California and Arizona, and in the moun- 
tains of Arizona on @. undulata. I am informed by perfectly 
reliable authority that it is common on the Persimmon in the 
southernmost counties of Illinois. L. F. Ward informs me he 
has observed it on Acer rubrum in the Dismal Swamp.
