Perak. Ulu Batang Padang, at 4.900 feet (Wray 128). 



In the Kew Herbarium a sheet of this is written up by 

 King as Mastixia gracilis, King, but the description of that 

 species (based on a plant collected in Perak at 3,900 feet by 

 Wray No. 1528) does not apply to the plant at all well, 

 especially in the length of the petiole is given as .2 — .25 in. 

 long, and the inflorescence as cymose. This plant has um- 

 bellate inflorescence much resembling that of A. alternifolium 

 and is clearly an Araliaceous plant.

 or five species ranging from Sumatra through New Guinea to 

 Australia.
