For the botanist, a lawn is a plant formation consisting of herbaceous species of low height (barely exceeding 20-30 cm in height), mainly grasses, such as grasslands. Leaving the ground bare in places, it can sprinkled with rare small shrubs. They host a rich biodiversity and are home to many different plants, sometimes endemic or rare (lawn service Florida Keys).
Ascending stems: usually come with short base which gradually grows longer towards the apex. They can either be simple or branched. Creeping stems: these variants grow on ground, rooting at the nodes. Their compounds often have knots, Stenotaphrum and Cynodon. When creeping stems rise to new plants at each node they are called stolons.
Floating stems: these float on water due to gaps or the presence of internodes Aerenchyma. Rhizomes: There are two types of rhizomes in grasses. A first type of short rhizomes is hunched and of defined growth, generating new plants next to original kills helping to increase its diameter, such as in Arundo donax and Spartina densiflora.
The second type of Rhizome is long of indefinite growth propagating some distance from the original clump. Examples of this second type are Sorghum halepense and Panicum racemosum. Pseudobulbos: are thickening of basal internodes enveloped by its leaf sheaths. They are rare in grasses, some examples are Amphibromus scabrivalvis and Phalaris tuberosa.
The lawns are found throughout the temperate zones including Europe, and all levels of vegetation (including alpin). Several factors determine the existence lawns including: local microclimates, soil types, the situation, the immediate presence of forests and wetlands, sunshine, slope. Lawns are subject to significant periods of drought, but the regional climate, especially rainfall, is not the most important.
They are generally herbs, although they may be woody like the tropicales, turfgrass, rhizomatous or stoloniferous bamboos. For the duration of its life cycle can annual, biennial or perennial. Annual grasses, as is logical to assume, reproduce only once during their life cycle -the case of wheat or oats, for example.
Their role was crucial to human activity as they allowed to feed livestock, especially sheep and goats. Other lawns of this type are born from the recent abandonment of vineyards. In this case, if man is not involved in their management, these environments naturally evolve into a forest stage through ecological succession. Many lawns have disappeared (overgrown, woody) abandoned for lack of profitability in early twentieth century. Since that time, 50 to 75% dry grasslands were perdues
Pseudopetiole: in many Bambuseas there is a contraction between the blade and the sheath that resembles a petiole; often this pseudopetiole is articulated with the blade and persistent. Blade is usually linear or lanceolate, entire in margin and parallel ribs. In tropical genera oblong sheets appear to broadly elliptic, and Pharus and Olyra. Neurolepis sheet (Bambusoideae) can have up to 4 meters long.
