Variation in Datura candida ‘ Buyés’ 
Most specimens of Daturas in the Valley of Sibundoy 
are called buyés borrachera by the Kamsa-speaking Sibun- 
doy, or D. candida ev. Buyés as described below. They 
represent several, or possibly many, genetic lines, as 
evidenced by marked differences in the size and shape of 
the flowers. At the present time, however, the natives 
are little, if at all, aware of these variations, and they do 
not discriminate verbally within their concept of buyés 
borrachera. For later purposes of comparison, it will be 
helpful here to record the limits of variation of D. can- 
dida ‘Buyés’ in the Valley of Sibundoy. To this end, a 
representative sample of leaves and flowers was taken 
from twenty-eight trees scattered throughout the area of 
the Valley inhabited by the Sibundoy. With the addition 
of other collections, there are thirty-seven trees repre- 
sented, to give an indication of the range of variability of 
this cultivar. Table I gives the range of variation in D. 
candida ‘Buyés’ for six of the eight characters found to 
be most useful in distinguishing the nine Sibundoy culti- 
vars of D. candida.

The most conspicuous feature of these trees is certainly 
the brilliant white corolla, but despite this, its variation 
in size has no formal recognition among the Sibundoy. 
In many flowers, the edge of the corolla between the 
lobes is emarginate, but in some it is straight or well
