Key: White dots indicate localities where each of the "Hundred Best Iris” was originated by a modern hybridizer. 
Solid green indicates habitat of various species of beardless iris. 
Shaded green indicates range of the bearded species. (Beardless species are also found throughout most of this area.) 
(It is interesting to note that the numerous species of wild iris, though very widely distributed, are confined exclu¬ 
sively to the Northern Hemisphere.)
