[6] Schultes, _Peyotes and Plants Used_, 135. The Reko etymology preferred by Schultes (p. 136) so far as botanical evidence goes derives peyotl from Aztec pi- (small) and -yautli or -yolli (herb with narcotic odor or action), making “peyotillo” a double diminutive. Schultes has accepted, at the instance of the present writer, the thesis that _Cacalia_ spp. might well enough fit the “velvety, cocoon-like” etymology, but argues nevertheless that “this etymology does not seem to explain the application of the same name to the great array of plants which possess no soft or silky parts whatsoever.” Schultes is undoubtedly right on this point in terms of descriptive botany; yet may not some items be included in our lists illegitimately? _Anhalonium prismaticum_ Lem., for example, is called hikuli, not peyote, and is only partly its terminological equivalent. And does the “little narcotic” etymology explain all these instances? [7] Urbina, in Harms, _Über das Narkotikum_, 31; Schultes, _op. cit._, 135. APPENDIX 2: PEYOTE AND THE MESCAL BEAN Far the commonest designation for peyote in the older literature is “mescal bean,” a curiously persistent misusage, since either in the dried or the green state _Lophophora williamsii_ resembles a bean even less than a mushroom, Safford’s teo-nanacatl. On probing more deeply into this confusion, a widespread pre-peyote narcotic cult of the southern Plains was discovered. The ethnographic results of this study are presented in the text, but a brief characterization of the “mescal bean” proper is essential as well. Collected specimens of the old Plains “red bean” (= mescal bean proper) have been identified by authorities at the Harvard Botanical Museum as _Sophora secundiflora_ (Ortega) Lag. ex DC.[1] Variously known as “mescal bean” (southern Plains), “colorín” (Coahuila, Nuevo León, Texas), “frijolillo” (Nuevo León, Texas), “frijolito” (Texas), “evergreen coral-bean,” “coral-bean” and “mountain laurel” (southern New Mexico), this plant grows from Coahuila to San Luis Potosí, western Texas and southern New Mexico, being specially characteristic of the dry limestone hills. It is not, however, the “mountain laurel” _Kalmia latifolia_, being a true member of the Fabaceae or Bean Family; the term “coral-bean” is likewise applied to two other legumes of Texas, both, however, _Erythrina_ spp., not _Sophora_.[2]
