Recent investigations have indicated how much re- 
mains to be done to clarify our understanding of the 
preparation of the South American hallucinogen made 
basically from the bark of Banisteriopsis Caapi (Spr. ex 
Griseb.) Morton or B. inebrians Morton (8, 20, 24). 
Although it has been shown that the additive caapi- 
pinima (‘‘painted caapi’’) of the Tukano Indians of the 
Rio Uaupes of Brazil was not the apocynaceous Pres- 
tonia (Haemadictyon) amazonica (Bth.) Macbride (26), 
as suggested a century ago by Spruce (27), and accepted 
widely, even in the chemical literature (11), several mem- 
bers of this family have been reported as admixtures: 
the crushed leaves of Malouetia Tamaquarina A. DeCan- 
dolle amongst the Makunas of the Colombian Vaupés 
(21) and a species of Tabernaemontana in Peru (8). 
Sundry solanaceous plants are so used. In the Rio 
Negro-Vaupés region, tobacco (Nicotiana Tabacum L.) 
is often added (2, 14, 21). The Sionas of the Colombian 
Putumayo employ a Datura, probably D. suaveolens 
Humboldt & Bonpland ex Willdenow (2, 14, 21). A 
species of Brunfelsia—possibly also taken alone as an hal-
