Dermatophyllum secundiflorum is a species of flowering shrub or small tree in the pea family, Fabaceae, that is native to the southwestern United States (Texas, New Mexico) and Mexico (Chihuahua and Coahuila south to Hidalgo, Puebla and Querétaro). Common names include Texas mountain laurel, Texas mescalbean, frijolito, and frijolillo. Although "mescalbean" is among the plant's common appellations, it bears no relation to the Agave species used to make the spirit mezcal, nor to the peyote cactus (Lophophora williamsii), which contains the hallucinogenic alkaloid mescaline.
