The existent climatic configuration in the Argentinean territory, as well as the disposition of the relief, they determine the existence of varied natural vegetable formations. The arboreal areas are represented by forests, forests and mounts, of those that spends gradually to the park and the savanna like transition areas, until arriving to the herbaceous formations: the prairie and the steppe. The regions present fitogeográficas in the Argentina are the South American and the antarctic one in which the vegetables are practically nonexistent; subdivided in counties and districts; the most representative are:

• Missionary forest
• Galleries and parks correntinos
• Forest chaqueño
• Tropical mountain forest (or tucumano-oranense)
• Herbaceous steppe
• Riverside forest
• Spinal
• Mount or mountain forest
• Steppe arbustiva
• Steppe Andean puneña
• Forest cordillerano (cold or subantártico)
• Steppe patagónica

It presents a closed vegetation, very rich in species, with several arboreal strata and a sotobosque of canes, bushes, grasses and mosses. Some of their copies are: guatambú, laurel, cedar, petiribí, lapacho, palm pindó, arborescent ferns, lianas and epífitas among those that orchids and ferns stand out.

This formation is prolonged along the rivers Paraná and Uruguay, showing again although something more impoverished, in the oriental area of the counties of the Chaco and Formosa.

In their vegetation forests are alternated in higher areas, pastizales in the plane and pajonales and tidelands in the depressions where accumulates water.

The ñandubay mounts, pruning, espinillo, chañar and locust, they appear alternate with herbaceous spaces in those that the espartillo prevails and several gramineous and caranday palmares and yatay. They are typical the camalotales formations and those dammed, formed by aquatic plants as the irupé, the cabbage and the lentil of water.

It prevails the vegetation caducifolia and xerófila with reduction of the leaves and presence of thorns to avoid the loss of water for perspiration. They are typical the quebrachos accompanied by guayacán, sacred stick, locust and thorny bushes as the chañar, the tusca and the vinal.

They are frequent the cactáceas (quimili, cardón) and the palms; toward the West and in the saline floors there is jume, it hides and cachiyuyo; in the southern mountain areas the molle prevails of drinking, coconut, churqui and scribble. In the branches there are líquenes, carnations of the air and plants climbers.

It is the domain of the grasses although it is presented very altered for the human presence. They can be different gramineous as the flechilla and diverse bushes among them the romerillo and the brusquilla.

In the lagoons and taken a bath aquatic grasses grow, rushes, cortaderas and totoras, those that are also in the depressed area of the bay Samborombón, together with espartillo and reed-mace. In the dunes of the Atlantic coast the vegetation is adapted to the sandy floor.

This mount extended in arch form, surrounds the pastizales pampeanos from the county of Among Ríos until the area of the Bay Blanca, being presented forests xerófilos that alternate with savannas and palmares. They are distinguished three areas with prevalence of different copies: the mount entrerriano with the ñandubay; the mount Cordovan santafecino with the locust and the mount puntano pampeano with the caldén.

Other species accompany those mentioned: espinillo, pruning, chañar and the palm. In Between Ríos and Santa Faith the herbaceous stratum is rich in species like espartillo, cortadera, cebadilla and red straw, as well as yatay palmares. In the area of the caldén they prevail white straw, I pasture puna and flechillas. In sandy atmospheres there are jonquil and male garlic and in the saline jume and cachiyuyo.

The vegetation impoverished by the aridity presents adaptations like the reduction of the leaves, the engrosamiento of the shaft and the appearance of thorns like in the cactáceas.

The characteristic copies are locust, sallow and maitén that usually locate next to the courses of water. In summer they present a sotobosque of bushes like espinillo, bull shade, piquillín, jarilla and retamo and grasses in those that coirón, cebadilla, straw and pichana prevail.
