Ridley 10071 from Kwala Pedas, Negri Sembilan has been identified by 
A. von Seemen in the Kew Herbarium as being probably Castanopsis echidno- 
carpa,A.DC. The material is so poor that I have thought it best not to include 
it in the key and descriptions. 
In his paper on the Flora of the Telém and Batang Padang Valleys in the 
Journ. Fed. Malay States Museum, vol. iv, page 63 (1909), Ridley mentions 
the finding of Castanopsis argentea, A. DC. His specimen is in the Kew Her- 
barium, in young fruit only, and seems to me to come nearer to C. Hystrix 
A. DC., but; to properly identify species of Castanopsis ripe fruit is indis- 
pensable.
