it was ‘‘intoxicating’’. I could get no further informa- 
tion at that time. The Witoto name of this plant in the 
Rio Karaparana was oo-hoo-na, the same name given to 
me by the informant, but this Indian name may refer 
generically to more than one species of Virola or even 
to species in related genera. A collection (22. 7. Martin 
et C.A. Lau-Cam 1272) of Dyalanthera parviflora from 
the Rio Napo in adjacent Peru, for example, bears the 
Witoto name w-Av-na. 
The Witotos rasp the inner part of the freshly stripped 
bark, roll the rasped tissue into balls and express the 
resin from it into a pot of water which is boiled for five 
or six hours, until the mass becomes a thick syrup that 
sticks to the wooden paddle that has been used to stir 
the boiling mixture. 
While this operation is progressing with the resin of 
Virola, another Indian reduces to ashes the bark of a 
‘‘large tree with long leaves, like matamata’’ that grows 
in floodland. We were fortunate in being able to collect 
flowering material of this tree in the Rio Loretoyacu 
region: it represents Gustavia Poeppigiana Berg ex 
Martius.” The Witoto name of this tree is he-rog. 
The ashes are placed in a funnel made of strong leaves, 
and cool water is poured over the ashes and allowed to 
seep through until ‘‘no more cloudiness leaches out’’. 
The water is then slowly boiled down until a greyish 
residue or ‘‘salt’’ is left. This is known in Witoto as 
le-sa.
