mine, the first malpighiaceous species from which a try p- 
tamine has been isolated (1, 6, 15). Similarly, the leaves 
of Psychotria viridis and P. carthaginensis (7, 20) have 
been found to contain the same tryptamine—again the 
first known occurrence of tryptamines in the family 
Rubiaceae. Obviously, the addition of leaves of these 
plants—as the addition of solanaceous plants with tro- 
pane alkaloids—greatly heightens the narcotic effects of 
the drink. That the utilization of Psychotria leaves is 
widespread has been shown by the recent discovery of 
this custom in the westernmost Amazon in Ecuador and 
Colombia, in several isolated localities in Amazonian 
Peru and in the southwestern Amazon of Brazil (7, 13, 
14, 16, 17, 20, 22). 
In pursuit of our studies of additives or possible addi- 
tives to ayahuasca, the following voucher specimens 
authenticating new data are offered. 
Teliostachya lanceolata Nees var. crispa Nees 
ev Martius F\. Bras. 9 (1847) 72. 
Peru: Departamento de Loreto, Iquitos and vicinity. *“Cultivated. 
Flowers white with violet. Toé negra.”’ July 15, 1967. R. Martin, 
T. Plowman et C. Lau-Cam 1638 [| Det. Plowman]. 
This variety of the acanthaceous T'eliostachya lanceo- 
lata is added to ayahuasca and may be used alone also as 
a narcotic. The collectors received the following data 
from a Kokama Indian informant: ‘‘1) Used as an ad- 
mixture to ayahuasca (Banisteriopsis Caapi). ‘Two 
branches are cooked with ayahuasca for about 11 hours. 
2) When taken alone, about 10 leaves are cooked gently 
for 7 hours. The effects (on the mind) last for three days, 
during which one converses with the spirit of the plant. 
Also causes loss of sight for three days.”’ 
Chemical studies have apparently not been carried out 
on Teliostachya (10). In view, however, of the suspected
