MATERIALS FOR A FLORA OF FORMOSA. Ei} 
As far as I can judge from the description of the variety @. 
Taiwanensis, it is so very different from D. crenata 8. et Z., that 
it is quite proper to raise it up to specific rank. The fruit of 
the present plant is very similar to those of Hrnry’s specimen 
at Kew.
