With regard to the botanical position of the foregoing species and so-called 
species, we have received the following letter from Professor Bayley Balfour :— 
“You find here that including what we ca.ll Azalea Vaseyi, which they 
(the American botanists) now make a distinct genus, Biltia, because the upper 
lobe of the corolla is external not internal, there are 12 species of Azalea in 
America. 
“ A. calendulacea (which they now call A. lutea).
