but B. Caapi and what appears to represent B. Rusbyana 
are cultivated for use as intoxicants. The collections cited 
below are all sterile and identification is, therefore, not 
certain, but, in each case, they were taken from plant 
material which I know, from personal experimentation, 
to possess narcotic properties. 
The 'Taiwano and Kabuyari Indians of the Rio Kana- 
nari, an affluent of the middle course of the Apaporis, 
prepare their kaheé from two kinds of Banisteriopsis, 
both cultivated. One vine had no leaves at the time of 
the Baile de la Sabaleta, when yajé is drunk, but the 
stems obviously belonged to a species of Banisteriopsis. 
The other is represented by the collection Schultes & 
Cabrera 13156a and corresponds in all vegetative charac- 
ters with Banisteriopsis Caapi. 
Those Makunas who live along the Rio Popeyaca, also 
an affluent of the Apaporis, prepare the drink in two 
ways: either with one species of Banisteriopsis or with 
two species of this genus, both cultivated. The drink is 
called haheé by the Makunas. When it is made from one 
species, Banisteriopsis Caapi (represented by Schultes & 
Cabrera 15587) is employed: this species is known in 
Makuna by the name reé-ma. When two species are 
used in the preparation of the drink, Banisteriopsis Caapi 
is mixed with a vine called me-ne-ka-heé-ma (‘‘vine of 
ha-heé™’) and referable probably to B. Rusbyana (Schultes 
& Cabrera 15588). Of Banisteriopsis Caapi, only the 
rasped bark is employed, but of B. Rusbyana either the 
leaves or the bark or both are utilized. With these 
natives, I took yajé twice; once made with bark from 
Schultes & Cabrera 15587 and leaves from Schultes & 
Cabrera 15588, and once with bark of Schultes & Cabrera 
15587 alone. Intoxication was induced in both eases, 
and I was unable to note that one preparation had dif- 
ferent or stronger effects than the other. Both of these
