Among tlie plants obtained by a native collector of the Royal 

 Botanic Garden, Calcutta, while working in the Kachin Hills under the 

 kind supervision of Lieutenant Oruddas, S.C., Commandant of the 

 Military Police Battalion at Myitkyina, one of the most striking is a 

 hitherto uncharacterised Araliaceous plant which cannot be referred to 

 any known genus of the order. The necessary generic definition, and 

 a detailed description of the species on which the new genus is based, 

 are herewith submitted to the Asiatic Society.
