    This species, despite its rough resemblence to Lophophora williamsii, is not hallucinogenic.
        L. williamsii has mescaline as its major alkaloid but L. koehresii contains only traces of mescaline which are pharmacologically inactive.

    Notice the Ariocarpus kotschoubeyanus growing to the upper left of the Lophophora koehresii in the upper left image?


    For a closer view of the plants we encountered see the next page.
