This plant does not seem to be distinct from the eastern species. Gray! refers 
to it as ‘forma occidentalis, T. grandis Nutt.,” without description. Therefore 
the citation in Watson’s Index, p. 27, as ‘ var. occidentalis Gray” is not warranted, 
for Dr. Gray himself did not consider it even a variety, practically reducing 
Nuttall’s name to a synonym.
