but I have not found that any of the forms of the same species 

 conies in accord with the Loo-chooan plant in respect of the 

 shape of leaves. Accordingly I have thought it better to regard 

 the latter as representing a new variety of the species. The 

 present variety differs from the type in having ovate leaves, quite 

 ix)unded at the base, acuminate at the apex, with three distinct 

 nerves, and two distinct lateral veins on both sides of the central 

 nerve. The leaves of the type are oblong, or obovately oblong, or 

 rarely ovate-oblong, much more obtuse at the apex, and nearly 

 acute at the base, pinninerved or obscurely three-nerved, with 

 more than six lateral veins on both sides of the central nerve. 

 The new variety is named in honour of Dr. T. Itö who has 

 done so much for the study of the flora of these interesting 

 Archipelago.
