Article V of the TREATY OF PEACE, FRIENDSHIP, LIMITS, AND SETTLEMENT BETWEEN THE UNITED STATES OF AMERICA AND THE UNITED MEXICAN STATES CONCLUDED AT GUADALUPE HIDALGO (known commonly as the Treaty of Guadalupe Hidalgo ) declared that the new boundary between the two republics of the United States and Mexico would lay "three leagues from land, opposite the mouth of the Rio Grande, otherwise called Rio Bravo del Norte, or Opposite the mouth of its deepest branch, if it should have more than one branch emptying directly into the sea; from thence up the middle of that river, following the deepest channel, where it has more than one, to the point where it strikes the southern boundary of New Mexico; thence, westwardly, along the whole southern boundary of New Mexico (which runs north of the town called Paso) to its western termination; thence, northward, along the western line of New Mexico, until it intersects the first branch of the river Gila; (or if it should not intersect any branch of that river, then to the point on the said line nearest to such branch, and thence in a direct line to the same); thence down the middle of the said branch and of the said river, until it empties into the Rio Colorado; thence across the Rio Colorado, following the division line between Upper and Lower California, to the Pacific Ocean. "
 It delineated the boundary through its text but wasn't written with much knowledge of the area's actually geography; A commissioner and surveyor from each country were appointed to precisely locate landmarks and accurately map the new border, relying on the treaty as their guide.
Eryngium foetidum is a tropical perennial herb in the family Apiaceae.
 Its scientific Latin name literally translates as "foul-smelling thistle".
 Common names include culantro ( or ), "shado beni", Mexican coriander and long coriander.
 It is native to Mexico and South America, but is cultivated worldwide, sometimes being grown as an annual in temperate climates.
 In the United States, where it is not well known outside Latino/Hispanic, Indo-Caribbean, and Caribbean communities, the common name "culantro" sometimes causes confusion with "cilantro", a common name for the leaves of "Coriandrum sativum" (also in Apiaceae), of which "culantro" is said to taste like a stronger version.
Eryngium articulatum is a species of flowering plant in the carrot family known by the common names beethistle and jointed coyote thistle.
 This plant is native to the northwestern United States from California to Idaho, where it is a plant of marshes and riverbanks.
 This is a sturdy, branching perennial herb with rounded, naked stems reaching maximum heights over one meter.
 It has a few sparse sharply serrated leaves at nodes and branching points along its stem.
 Atop the stem is the rounded to egg-shaped flower head, which looks superficially like that of a thistle, mainly due to its spikiness and lavender color.
 It is fringed with up to 17 spiny, toothed, pointed bracts, each up to about two centimeters long.
 Each flower head is packed full of small lavender flowers.
Eryngium is a genus of flowering plants in the family Apiaceae.
 There are about 250 species.
 The genus has a cosmopolitan distribution, with the center of diversity in South America.
 Common names include eryngo and amethyst sea holly (though the genus is not related to the true hollies, "Ilex").

Eryngium leavenworthii, also known as Leavenworth's eryngo, is an annual plant in the parsley family that is native to the central United States.
 It can reach heights up to 3 feet.
 It inhabits dry rocky prairies, roadside fields, open woodlands and waste areas.
 The plant is mostly found in areas with limestone or chalk soils.
 Its flowers appear between July to September, although in some areas the flowers may bloom as late as November.
 The flower ranges in length from 1 1/2" to 3" and in width approximately 1/2".
 It is frequently mistaken for thistle.
 The flowers sit atop elongated stems on spiked leaves and form cones of purple or wine colored, tightly clustered blossoms that resemble small fuzzy pineapples.
 It was named after, Melines Conklin Leavenworth (1796–1862) who is credited with its discovery.
The Hispanos of New Mexico (less commonly referred to as Nuevomexicanos) are people of Spanish or Amerindian-Hispanic descent native to the region of Santa Fé de Nuevo Mexico, now the Four Corners region but primarily centering on New Mexico and southern Colorado, in the United States.
 For most of its modern history, New Mexico belonged to Spain (16th century – 1821) and later Mexico (1821–1848).
 Like some of the "Californios" and "Tejanos", most settlers in New Mexico were of Spanish ancestry (either directly or through Mexico).
 The descendants of the settlers make up an ethnic community of more than 340,000 in New Mexico, with others in southern Colorado.
