On the mesas of Tamaulipas and Jalisco, in the dry infertile regions of Mexico south of the Rio Grande, a cactus grows amid the rocks and sand. It is not erect and magnificent like the Saguaro or the bearer of gorgeous flowers like the night-blooming Cereus. It is, in fact, a thoroughly insignificant little pincushion projecting a bare three inches above the barren soil, a round, dark green protuberance connected to a carrot like taproot, its surface covered with tufts of silky hairs. Though utterly uninspiring in appearance, this humble cactus, Lophophora williamsii, (Formerly Anhaloniurn lewinii) produces in its fleshy top one of the strangest drugs in the pharmacologists' collection.
