Richard Evans Schultes

The Narcotic Mushroom of the Aztecs

Schultes's botanical account of his 1938-39 fieldwork with Blas Pablo Reko among the Mazatec, tracing the teonanácatl rediscovery from Reko's 1923 letter through Robert Weitlaner's 1936 visit to Huautla de Jiménez. Schultes identifies the mushroom as Paneolus campanulatus var. sphinctrinus.

The Narcotic Ololiuqui of the Aztecs

Schultes's botanical monograph settling the identity of ololiuqui, the Aztec morning-glory narcotic. He credits Urbina's 1897 identification as Rivea corymbosa, corrects Safford's 1915 misidentification as jimsonweed, and surveys continued ritual and medicinal use among the Chinantec, Mazatec, Mixtec, and Zapotec of Oaxaca.
