tent of their knowledge. For example, very few, perhaps 
only the medicine-men, are able to name all the cultivars 
accorded recognition by the culture; but even some of 
these may be unaware of cv. Salamain. Many informants 
can provide names and some kind of information on four 
or five different borrucheras. The ‘‘average’’ landowner 
may own several ‘Buyés’ trees but probably has no eco- 
nomically important cultivar. Both his knowledge and 
his curiosity extend beyond the Jorracheras in his own 
garden. Following is a summary of economic uses. 
1. ‘Guamuco’—A poultice of the flowers, together with 
‘Culebra’ leaves and the stems and leaves of Phenawx 
integrifolius Wedd. is used to treat rheumatism. The 
leaves are sometimes heated and tied over swollen 
infections, or an infusion of the leaves may be used 
to bathe infections. 
2. ‘Sangre’-—Same as ‘Guamuco’. 
3. ‘Buyés’—Leaves of this cultivar are sometimes pow- 
dered and applied topically with other drugs to relieve 
rheumatic pain. 
One informant said he always uses the fruit of this at 
maize planting time. He plants a few fruits along with 
the maize in order to prevent grubs or other soil pests 
from eating the germinating seed. This interesting ges- 
ture to protect the crop can scarcely be a general prac- 
tice, however, because fruiting is rare. This is the only 
use ever encountered for any Datura fruit or seed in the 
Valley of Sibundoy. 
4. *‘Dientes’—Same as ‘Buyés’. 
5. ‘Ocre’—No use encountered. 
6. ‘Biangin’—The leaves and flowers can be ground
