Takeda— Old World Species of the Genus Mahonia. 245 



The present investigation clearly shows that our knowledge 

 of the genus Mahonia has been and still is very imperfect. It 

 is remarkable how numerous are the species which have errone- 

 ously been recorded as M. napaulensis, without their real nature 

 being satisfactorily understood. No doubt many more new 

 species are still to be found, while many more specimens of the 

 known species must be collected and carefully examined before 

 they can be adequately defined.
