MATERIALS FOR A FLORA OF FORMOSA. Vit 
Has. Taito : Daironsan, leg. T. KawaKamr ct U. Mort, (No. 2184). 
The present plant was first identified with Pieris formosa D. Don 
by Prof. J. Matsumura. I was also of the same opinion as the 
Professor regarding the reference of the plant, as the figures given 
in Wicurt, Ic Pl. t. 1200 quite agree with it. Since coming to 
_ Kew, when | have examined the type of P. formosa D. Don, I have, 
however, found that the type does not agree with the Formosan 
plant. The inflorescence of the latter spreads less, the flowers 
are smaller, the leaves are obovately spathulate, less acute at the 
apex, more obtusely serrate on the margin, and very faintly reti- 
culated on the surface. There are at Kew some specimens {rom conti- 
nental China, referred to P. formosa D. Dox. They are also different 
from my plant.
