Dermatophyllum Purpusii
''Dermatophyllum'' is a genus of three or four species of shrubs and small trees in the subfamily Faboideae of the pea family, Fabaceae. The genus is native to southwestern North America from western Texas to New Mexico and Arizona in the United States, and south through Chihuahua, Coahuila, and Nuevo León in northern Mexico. Members of the genus are commonly known as mescalbean, mescal bean, or ''frijolito''. One of the common names of ''Dermatophyllum secundiflorum'' is Texas mountain laurel, although the name mountain laurel also refers to the very dissimilar and unrelated genus ''Kalmia'' (family Ericaceae) and the name laurel refers generally to plants in the unrelated order Laurales. Although still commonly treated in the genus ''Sophora'', recent genetic evidence has shown that the mescalbeans are only distantly related to the other species of ''Sophora''. Species ''Dermatophyllum'' comprises the following species: * '' Dermatophyllum arizonicum'' ( S.Watson) Vincent— ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dermatophyllum Secundiflorum
''Dermatophyllum secundiflorum'' is a species of flowering shrub or small tree in the family Fabaceae that is native to the Southwestern United States (Texas, New Mexico) and Mexico ( Chihuahua and Coahuila south to Hidalgo, Puebla, and Querétaro). Its common names include Texas mountain laurel, Texas mescalbean, ''frijolito'', and ''frijolillo''. Name 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. Description An evergreen, its leaves are pinnately compound, with small, roughly spatulate leaflets; the leaflets are rather thick, and waxy to the touch. Never tall, and rarely having a straight trunk, its bark is smooth in all but the oldest specimens. It grows slowly to a height of and a crown diameter of . Extremely fragrant purple flowers, resembling the smell of grape soda, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texas
Texas (, ; Spanish language, Spanish: ''Texas'', ''Tejas'') is a state in the South Central United States, South Central region of the United States. At 268,596 square miles (695,662 km2), and with more than 29.1 million residents in 2020, it is the second-largest U.S. state by both List of U.S. states and territories by area, area (after Alaska) and List of U.S. states and territories by population, population (after California).

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...
