LXXXVIII. SOLANACE. 
In the highlands of Huilla, where manioc does not succeed, the 
common potato was introduced in 1840, and is extensively 
cultivated by the negroes of Munhaneca in Humpata; in 
Welwitsch’s time the potato disease had not appeared there. 
After a prolonged diet of potatoes in Humpata, the Monanos, who 
were quite unaccustomed to them, suffered from an outbreak of 
dysentery. 
The Daturas appear to have immigrated from Asia; they, as 
well as hemp, have the Bunda name “ Sambalage,” derived from 
dilage, which means madness ; their poisonous narcotic properties 
have been known to the negroes from the earliest times. 
Welwitsch was convinced in several instances that the seeds were 
intentionally used to produce poisoning, which in each case was 
attributed to other poisonous plants known only to the negroes. 
The drugging of palm wine with Datura, which is supposed to 
be caused by the so-called “ Fel de Jacari,” supplies an emphatic 
proof,
