round,’ with reference to the seed of ololiuqui. It is a 
narcotic Mexican plant, the dried seeds of which, pul- 
verized and soaked in pulque or tepache, produce an in- 
toxicating drink called piwle. Piule was formerly used as 
a sorecerer’s potion and is still employed as an intoxicant 
in secluded parts of Mexico, especially in Oaxaca (16). 
There has been much dispute concerning the botani- 
‘al identification of ololiuqui. Mexican authorities (8,12, 
16, 84) hold that it is Rrvea corymbosa (L.) Hall.f. (T'ur- 
bina corymbosa Rat., Ipomoea sidaefolia Choisy). This 
agrees with the identification of ololiuqui seeds received 
by the writer from Mexico (27). Urbina (84) reports that 
other species of [pomoea are also called ololiuqui. Several 
other plants are known under the name puzzle.” 
Sahagun (25) described two ololiuqui plants. One, 
apparently a member of the So/anaceae, probably Phy- 
salis sp., was called wizicamatic;, this was medicinal for 
indigestion, but had no narcotic properties."” The other, 
coatl-wovwouhqui (*‘green snake’’), obviously a member of 
the Convolvulaceae, was medicinal for rheumatism and 
possessed drastic intoxicating properties when taken as 
a drink.” 
Hernandez (8) described and figured ololiuqui or coax- 
huitl (“‘snake plant’’) under the caption De Ololiuhquit 
seu planta orbicularium foliorum as amember of the Con- 
volvulaceae with thick, green, cordate leaves, large white 
flowers, and ‘‘coriander-like’’ seeds. He reported that it 
was an aphrodisiac,a stimulating tonic,a cure for syphilis, 
an analgesic, a carminative, a cure for colds, and a help 
for sprains, fractures, pelvic cramps in women, and un- 
natural swellings. Mixed with milk and Capsicum spp., 
and applied to the head and forehead, it was thought to 
be a cure tor certain eye troubles. 
De la Serna (30) attributed to ololiuqui intoxicating 
properties similar to those of peyote and teonanacatl.
