Prosopis humilis, the algarrobilla or algaroba (carob in Spanish), is a mesquite, a flowering plant and a tree species in the genus "Prosopis" found in Argentina.
Prosopis nigra (synonym "Prosopis algarrobilla") is a South American leguminous tree species that inhabits the Gran Chaco ecoregion (in particular, the transition zone between the Wet Chaco and the Southern Chaco), in Argentina and Paraguay.
 It is known as algarrobo negro in Spanish, which means "black carob tree" (the Spanish settlers gave it that name, as they did with many other species of genus "Prosopis", because of its similarity to the European carob tree).
 It is also variously called "algarrobo dulce", "algarrobo morado" and "algarrobo amarillo" ("sweet", "purple" and "yellow" carob tree, respectively).
Lavatera assurgentiflora – now classified as Malva assurgentiflora, the island mallow, mission mallow, royal mallow, island tree mallow, malva rosa, is a species of flowering plant in the mallow family.
Malva verticillata, also known as the Chinese mallow or cluster mallow, is a species of the mallow genus "Malva" in the family of Malvaceae found in East Asia.
 "M. verticillata" is an annual or biennial that grow up to 1.7 meters in high and can inhabit woodland areas of different soil types.
 In temperate climates, it flowers from July to September and the seeds from August to October.
 The flowers of the plant are self-fertile but can also be pollinated by insects.
Prosopis is a genus of flowering plants in the pea family, Fabaceae.
 It contains around 45 species of spiny trees and shrubs found in subtropical and tropical regions of the Americas, Africa, Western Asia, and South Asia.
 They often thrive in arid soil and are resistant to drought, on occasion developing extremely deep root systems.
 Their wood is usually hard, dense and durable.
 Their fruits are pods and may contain large amounts of sugar.
 The generic name means "burdock" in late Latin and originated in the Greek language.
Malva sylvestris is a species of the mallow genus "Malva" in the family of Malvaceae and is considered to be the type species for the genus.
 Known as common mallow to English-speaking Europeans,
Malva arborea (also known as Lavatera arborea, or, more recently as Malva eriocalyx), the tree mallow, is a species of mallow native to the coasts of western Europe and the Mediterranean region, from the British Isles south to Algeria and Libya, and east to Greece.
Malva pusilla, also known as Malva rotundifolia (the latter of which is now officially rejected by botanists), the low mallow, small mallow, or the round-leaved mallow, is an annual and biennial herb species of the Mallow genus "Malva" in the family of Malvaceae.
 Malva is a genus that consists of about 30 species of plants.
 This genus consists of plants named mallows.
 Mallows grow in many regions, including temperate, subtropical, and tropical areas.
Prosopis pallida is a species of mesquite tree.
 It has the common names kiawe (in Hawaii), huarango (in its native South America) and American carob, as well as "bayahonda" (a generic term for "Prosopis") and "algarrobo blanco" (usually used for "Prosopis alba").
 It is a thorny legume, native to Colombia, Ecuador and Peru, particularly drier areas near the coast.
 While threatened in its native habitat, it is considered an invasive species in many other places.
Malva is a genus of about 25–30 species of herbaceous annual, biennial, and perennial plants in the family Malvaceae (of which it is the type genus), one of several closely related genera in the family to bear the common English name mallow.
 The genus is widespread throughout the temperate, subtropical and tropical regions of Africa, Asia and Europe.
 The word "mallow" is derived from Old English "malwe", which was imported from Latin "malva", cognate with Ancient Greek μαλάχη (malakhē) meaning "mallow", both perhaps reflecting a Mediterranean term.
 A number of species, previously considered to belong to "Lavatera", have been moved to "Malva".
