Dermatophyllum secundiflorum Dermatophyllum secundiflorum 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. It is well-adapted to arid and semi-arid habitats but is most common in riparian
Ionic compound but stay in the remaining solution, and when they become sufficiently concentrated, nucleation occurs, and they crystallize into an ionic compound. This process occurs widely in nature, and is the means of formation of the evaporite minerals. Another method of recovering the compound from solution involves saturating a solution at high temperature and then reducing the solubility by reducing the temperature until the solution is supersaturated and the solid compound nucleates. Insoluble ionic compounds can be precipitated by mixing two solutions, one with the cation and one with the anion in it. Because all solutions are electrically neutral, the two
