68 ART, I,—B. HAYATA? 
but I have not found that any of the forms of the same species 
comes 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 
rounded 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. It6 who has 
done so much for the study of the flora of these interesting 
Archipelago.
