The Zacatonal is a montane grassland and shrubland ecoregion of central Mexico. Geography The Zacatonal consists of several enclaves of grassland and shrubland occupying the highest peaks of the Trans-Mexican Volcanic Belt, covering about . Zacatonal is found above 3500 meters elevation on the volcanoes Popocatépetl, Iztaccihuatl, Malinche, Nevado de Toluca, Cofre de Perote, Pico de Tancítaro, and Pico de Orizaba.Brown, David E., and Markings, Elizabeth (2014). "A Guide to North American Grasslands" ''Desert Plants'', Volume 29, Number 2, 2014. Zacatonal is surrounded by the Trans-Mexican Volcanic Belt pine-oak forests ecoregion at lower elevations.

Pico De Tancítaro
Pico de Tancítaro, also known as Volcán Tancítaro, is a volcanic mountain in Mexico. It is located in Tancítaro municipality in Michoacán state. It is the highest peak in Michoacán. Geology Pico de Tancítaro is an andesitic-dacitic stratovolcano. It was active from 800,000 to 237,000 years ago, and is currently believed to be extinct. It is part of the much larger Michoacán–Guanajuato volcanic field. Portions of the volcanic field are still active. Parícutin is a young volcano located 11 km northeast of Pico de Tancítaro. It first erupted in 1943 and remained active and grew in size until 1952. Ecology Plant communities on the mountain include pine-oak forest, open pine forest, and montane mesophyll or cloud forest, with alpine grasslands, known as Zacatonal, at higher elevations."El Área de Protección de Flora y Fauna Pico de Tancítaro, proveedora de agua de al menos a 82 comunidades".

Nevado De Toluca
Nevado de Toluca () is a stratovolcano in central Mexico, located about west of Mexico City near the city of Toluca. It is the fourth highest of Mexico's peaks, after Pico de Orizaba, Popocatépetl and Iztaccíhuatl. The volcano and the area around it is now a national park. Etymology It is often called by the Nahuatl name Xinantecatl which is usually translated as The Naked Lord, ''Señor Desnudo'' in Spanish, although other etymologies have been suggested such as "Lord of the Corn Stalks", Tzinacantecatl or Zinacantepetl (Mountain of the Bats). Further evidence regarding the etymologies of this mountain has surfaced after many archeology discoveries in and around the area. It has been concluded that its correct etymology is Chicnauhtecatl meaning "Lord of Nine", probably referring to the various deep lakes at the top of the cone. Description The volcano has a wide summit caldera which is open to the east. The highest summit, the Pico del Fraile (Friar's Peak), is on ...

Potentilla Staminea
''Potentilla'' is a genus containing over 300Guillén, A., et al. (2005)Reproductive biology of the Iberian species of ''Potentilla'' L. (Rosaceae).''Anales del Jardín Botánico de Madrid'' 1(62) 9–21. species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae. Potentillas may also be called cinquefoils in English, but they have also been called five fingers and silverweeds. Some species are called tormentils, though this is often used specifically for common tormentil (''P. erecta''). Others are referred to as barren strawberries, which may also refer to '' P. sterilis'' in particular, or to the closely related ''Waldsteinia fragarioides''. Several other cinquefoils formerly included here are now separated in distinct genera - notably the popular garden shrub ''P. fruticosa'', now '' Dasiphora fruticosa''. Potentillas are generally found throughout the northern continents of the world (holarctic), though some occur in montane biome ...

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penstemon Gentianoides
''Penstemon'' , the beardtongues, is a large genus of roughly 250 species of flowering plants native mostly to the Nearctic, but with a few species also found in the North American portion of the Neotropics. It is the largest genus of flowering plants endemic to North America. Formerly placed in the family Scrophulariaceae by the Cronquist system, new genetic research has placed it in the vastly expanded family Plantaginaceae. They have opposite leaves, partly tube-shaped, and two-lipped flowers and seed capsules. The most distinctive feature of the genus is the prominent staminode, an infertile stamen. The staminode takes a variety of forms in the different species; while typically a long straight filament extending to the mouth of the corolla, some are longer and extremely hairy, giving the general appearance of an open mouth with a fuzzy tongue protruding and inspiring the common name beardtongue. Most penstemons are deciduous or semi-evergreen perennial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The highest diversity is in eastern Asia, with 352 species accepted in China alone. Taxonomy The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in livestock. The genus name ''Pedicularis'' is from the Latin ''pediculus'' meaning louse.

Oxalis
''Oxalis'' ( (American English) or (British English)) is a large genus of flowering plants in the wood-sorrel family Oxalidaceae, comprising over 550 species. The genus occurs throughout most of the world, except for the Polar region, polar areas; species diversity is particularly rich in tropical Brazil, Mexico, and South Africa. Many of the species are known as wood sorrels (sometimes written "woodsorrels" or "wood-sorrels") as they have an acidic taste reminiscent of the sorrel proper (''Rumex acetosa''), which is only distantly related. Some species are called yellow sorrels or pink sorrels after the color of their flowers instead. Other species are colloquially known as false shamrocks, and some called sourgrasses. For the genus as a whole, the term oxalises is also used. Description and ecology These plants are annual plant, annual or perennial plant, perennial. The leaves are divided into three to ten or more obovate and top-notched leaflets, arranged palmately with all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
