Quercus Durifolia
''Quercus durifolia'', commonly known as encino colorado, is a species of oak tree native to Mexico. Description ''Quercus durifolia'' is a small evergreen tree that typically reaches in height, occasionally growing to 15 meters. Leaves are lanceolate or ovate, glossy and dark-green on the top and tomentose on the underside. The bark is dark gray to black, smooth when young and becoming rough and fissured with age.

Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of The Sierra Madre Occidental
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn Woodpecker
The acorn woodpecker (''Melanerpes formicivorus'') is a medium-sized woodpecker, long, with an average weight of . Taxonomy The acorn woodpecker was formally described in 1827 by the English naturalist William John Swainson under the binomial name ''Picus formicivorus'' from a specimen collected in Mexico. The specific epithet combines the Latin ''formica'' meaning "ant" with ''-vorus'' meaning "eating". The type locality is Temascaltepec in Mexico. The acorn woodpecker is one of 24 species now placed in the genus ''Melanerpes'' that was introduced by Swainson in 1832. Within ''Melanerpes'' the acorn woodpecker is sister to a clade containing two South American species: the white woodpecker (''Melanerpes candidus'') and the white-fronted woodpecker (''Melanerpes cactorum''). Seven subspecies are recognised: * ''M. f. bairdi'' Ridgway, 1881 – Oregon (USA) to north Baja California (Mexico) * ''M. f. angustifrons'' Baird, SF, 1870 – south Baja California (Mexico) * ...

Tomentose
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and '' Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in '' Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sierra Madre Occidental Pine–oak Forests
The Sierra Madre Occidental pine–oak forests ( es, Bosques de pino-roble de la Sierra Madre Occidental) are a Temperate broadleaf and mixed forests ecoregion of the Sierra Madre Occidental range from the southwest USA region to the western part of Mexico. They are home to a large number of endemic plants and important habitat for wildlife. Geography The Sierra Madre Occidental run north to south in western Mexico from the center of the country towards the United States border. The Sierra Madre Occidental is Mexico's largest range, and the ecoregion extends approximately 1,200 kilometers from southern Arizona to northern Jalisco.
