The foreign species of ('oiiidsrliiniin have been merged with Liuiiftticiiin 

 and our own species put into Scliiiiiin by Bentham it Hooker. Their 

 decision in referen(.o to our species was based upon immature fruit, while 

 study of a (|uantity of fine fruiting material has led us to restore it to generic 

 rank. 5 It differs so decidedly from our definition of LignHiirum that it 

 is only necessary to call attention to the characters which separate it tiom
