The Violet which forms the subject of our illustration 
is one which was originally discovered on Mount Olympus 
in Bithynia, but which, as Becker has shown, occurs also 
in Macedonia and, according to the same authority, may 
ibly also occur in Montenegro. It was for a long 
time believed by authorities so competent as Boissier and 
Halacsy to be a native also of Greece, but Becker has given 
good reasons for the treatment of the Greek specimens 
named V. gracilis by Boissier as the basis of a distinet 
variety of the somewhat different species V. heterophylla, 
Bertol. The species now figured, V. gracilis, is a hardy 
Fesrvary, 1914.
