II. Plants known as ‘‘peyote’’ 
A list of those plants which, in Mexico, are popularly 
classed as “‘peyote’’ would include, in addition to the 
Convolvulaceae described above, the following: among 
the Cactaceae— Ariocarpus fissuratus (Kngelm.) K. 
Schum. (16), A. retusus Scheidw.(2), and A.hotschoubcy- 
anus (ILem.) K. Schum. (2), Astrophytum myriostigma 
Lem. (18), 4. asterias (Auce.) Lem. (3), and A.capri- 
corne Dietrich (3), Pelecyphora aselliformis Khrenb. (3), 
Strombocactus disciformis DC. (8), Aztehium ritteru 
Boedeker” (16), Obregonia denegrii Fric.” (16), Doli- 
chothele longimamma Britton & Rose (4), and Solisia 
pectinata Britton & Rose (4); among the Crassulaceae— 
Cotyledon caespitosa Haw. (4) and several other species 
(16); among the Compositae—Cacalia cordifolia HBK. 
(34,22) and probably also several other species (34), Sen- 
ecio calophyllus Hemsl. (4), 8. Hartwegii Benth. (4), 
S. Grayanus Hemsl. (15), 8S. tolucanus DC. (15), S. cer- 
variaefolhus Sch. Bip. (4), and S.albo-lutescens Sch. Bip. 
(12): among the Leguminosae—Rhychosia longeracemosa 
Mart. & Gal. (15); and among the So/anaceae— Datura 
meteloides IOC. ex Dunal (15). 
All of these ‘‘peyotes’’ are said to be either narcotic 
or medicinal, a fact which seems to lend support to the 
Reko etymology. Chemical corroboration of these re- 
ported properties is impossible in many cases because of 
the lack of investigation of these somewhat obscure 
plants. Anhalin, the one ‘‘anhalonium alkaloid’’ usually 
absent in Lophophora Wilhamsiu, has been found in sev- 
eral species of Ariocarpus (86) and is thought to be 
present in the other members of the Cactaceae known as 
peyote. Astrophytum myrtostigma, A.asterias, A.capri- 
corne, Pelecyphora aselliformis, Dolichothele longimam- 
ma, and Solisia pectinata have not been investigated
