Chenopodium Aciculare
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascendin ...

Chenopodium Berlandieri
''Chenopodium berlandieri'', also known by the common names pitseed goosefoot, lamb's quarters (or lambsquarters), and ''huauzontle'' ( Nahuatl) is an annual herbaceous plant in the family Amaranthaceae. The species is widespread in North America, where its range extends from Canada south to Michoacán, Mexico. It is found in every U.S. state except Hawaii. The fast-growing, upright plant can reach heights of more than 3 m. It can be differentiated from most of the other members of its large genus by its honeycomb-pitted seeds, and further separated by its serrated, evenly lobed (more or less) lower leaves. Although widely regarded as a weed, this species was once one of several plants cultivated by Native Americans in prehistoric North America as part of the Eastern Agricultural Complex. ''C. berlandieri'' was a domesticated pseudocereal crop, similar to the closely related quinoa ''C. quinoa.'' It continues to be cultivated in Mexico as a pseudocereal, as a leaf vegetable, ...
