the only shrub met with towards the top of the volcanic 
cone of Gunong Dempo in Passumah, where it is called 
Kayo Umur panjang, or the Tree of long Life, probably 
from its maintaining itself at elevations where the other de-

infusion of the leaves is drunk as a substitute for tea ; and it 
is known to the natives by the name of the Tea Plant.
