ously known as telepathine, yageine or banisterine. He 
stated, however, that it might also be found in ‘ta num- 
ber of related plants or forms** and quoted Morton in 
citing Banisteriopsis Rusbyana and Banisteria longialata 
as admixtures known by the names of oco-yagé and 
chagro panga. 
O’Connell and Lynn (60), working on material of Ban- 
istertopsis inebrians from the Putumayo of Colombia, 
found that the stems contain harmine and the leaves ‘‘an 
alkaloid which was partly identified as harmine.’’ The 
work of O’Connell and Lynn is noteworthy as represent- 
ing apparently the second chemical investigation carried 
out on material of Banisteriopsis identified through her- 
barium material. 
Mors and Zaltzman published a most interesting con- 
tribution in 1954 (56) in which they indicated their opin- 
ion, based on chemical examination, that yageine was 
different from harmine. On the basis of a brief review of 
the literature, they concluded that eaapi and ayahuasea 
were referable to Banisteriopsis Caapi but that yagé was 
not the same narcotic. 
Most recently, Fabre (21) published an historical re- 
view of caapi, ayahuasca and yajé, indicating his belief 
that only one species 
Banisteriopsis. Caapi--is_ the 
source of these narcotics, though citing Spruce that, 
amongst certain tribes, another plant may oftentimes be 
added in the preparation of the narcotic drink.

Although Morton (57) has convincingly shown why 
the generic epithet Banisteria is not available for the 
group of malpighiaceous plants which should be called 
Banisteriopsis, in accordance with the lucid arguments 
of Robinson (76), there is a tendency to persist in the 
incorrect use of the name Banisteria. This tendency is
