NeltumaNeltuma is a genus of flowering plants in the pea family (Fabaceae). It includes 43 species native to the Americas, which were previously placed in genus Prosopis. The species range from the southwestern and central United States through Mexico, Central America, the Caribbean, and South America to southern Argentina and Uruguay. Along with related species in the genus Strombocarpa, some species are known as mesquites. Species43 species are accepted: Neltuma affinis(Spreng.)
ProsopisProsopis is a genus of flowering plants in the family Fabaceae. The current circumscription of the genus contains three species found in northern Africa, the Middle East, Central and South Asia. Previously it also contained around 40 species of spinytrees and shrubs found in subtropical and tropical regions of the Americas and Africa, now mostly placed in genera Strombocarpa and Neltuma.

AmericasLandmass comprising North and South AmericaThe Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America. When viewed as a single continent, the Americas are the second largest continent by area after Asia and the third largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and constitute the "New World", in contrast to the "Old World" of Afro-Eurasia.
Before PresentBefore Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year".
StrombocarpaStrombocarpa is a genus of flowering plants in the pea family (Fabaceae). This genus was previously classified as a section of genus Prosopis. It includes ten species, which are native to the southwestern United States and northern Mexico, or to southern South America from Peru through Bolivia and northern and central Chile to southern Argentina. Ten species are accepted: Strombocarpa abbreviata (Benth.) Hutch.
Old WorldThe "Old World" (Latin: Mundus vetustus) is a term for Afro-Eurasia coined by Europeans after 1493, when they became aware of the existence of the Americas, Oceania, and Antarctica. It is used to contrast the continents of Africa, Europe, and Asia in the Eastern Hemisphere, previously thought of by the Europeans as the entire world, with the "New World", the newly encountered lands of the Western Hemisphere, particularly the Americas.
Mexican SpanishMexican Spanish (Spanish: español mexicano) is the variety of dialects and sociolects of the Spanish language spoken in Mexico and its bordering regions. Mexico has the world's largest number of Spanish speakers, more than double any other country. Spanish is spoken by over 99% of the population, being the mother tongue of 93.8%, and the second language of 5.4%.
LegumeLegumes are plants in the pea family Fabaceae (or Leguminosae), or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption, but also as livestock forage and silage, and as soil-enhancing green manure.
Lumpers and splittersLumpers and splitters are opposing factions in any academic discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example, schools of literature, biologicaltaxa, and so on. A "lumper" is a person who assigns examples broadly, judging that differences are not as important as signature similarities.
Nitrogen fixationNitrogen fixation is a chemical process by which the abundant but relatively inert molecular dinitrogen (N2) is converted into bioavailablenitrogen compounds such as ammonia (NH3) and nitrates (NO3). It occurs both biologically and abiologically, the latter either naturally through weather phenomena (e.g. lightning) or artificially by chemical industries.
NahuatlNahuatl (English: NAH-wah-təl; hispanicized from Nawatl pronounced [ˈnaːwat͡ɬ] ), Aztec, or Mexicano is a language or, by some definitions, a group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by about 1.7 million Nahuas, most of whom live mainly in Central Mexico and have smaller populations in the United States. Nahuatl has been spoken in central Mexico since at least the seventh century AD.*As an Amazon Associate I earn from qualifying purchases.
