TREE DATURA DRUGS OF THE 
COLOMBIAN SIBUNDOY' 
BY 
ME.LvIN L. BristTo.’ 
IN southernmost Colombia high on the eastern flank of 
the Andean cordillera lies a small and isolated montane 
basin, the Valley of Sibundoy (Plate NLVIII). Several 
thousand Kamsi-speaking Sibundoy and three Inga- 
speaking groups have inhabited the Valley for several 
centuries, perhaps for much longer.” The collapsing agri- 
cultural terraces clearly visible at many places on the 
valley sides indicate a populous pre-hispanic occupation, 
and the Sibundoy believe that their ancestors have lived 
in the Valley from very early times. As yet, however, 
there is no evidence linking the early terrace builders 
with the Sibundoy or with any other native group in 
southern Colombia. 
Despite the apparent isolation of the Valley of Sibun- 
doy, the natives have probably always been in contact 
with a diversity of other aboriginals. Today, as in the 
Sixteenth Century, there are three trails leading out of 
the Valley to the east, west and north. Two of these 
have recently been supplanted, for a road now connects 
the highland capital of Pasto twenty miles to the west
