Bearded Helmetcrest
The bearded helmetcrests (''Oxypogon'') are a genus of hummingbird in the family Trochilidae. They are found in Colombia and Venezuela. Primary natural habitat is subtropical or tropical high-altitude grassland, known as páramo. The genus contains four species. Taxonomy and species list The genus ''Oxypogon'' was introduced in 1848 by the English ornithologist John Gould. The type species was subsequently designated as the green-bearded helmetcrest. The genus name combines the Ancient Greek ''oxus'' meaning "sharp" or "pointed" with ''pōgōn'' meaning "beard". The genus contains four species: * White-bearded helmetcrest, ''Oxypogon lindenii'' * Green-bearded helmetcrest, ''Oxypogon guerinii'' * Blue-bearded helmetcrest, ''Oxypogon cyanolaemus'' * Buffy helmetcrest, ''Oxypogon stuebelii'' These four species were formerly all considered as subspecies of what was known as the bearded helmetcrest (''Oxypogon guerinii''). The bearded helmetcrest was split into four separate sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Castilleja
''Castilleja'', commonly known as paintbrush, Indian paintbrush, or prairie-fire, is a genus of about 200 species of annual and perennial herbaceous plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and one species as far west as the Kola Peninsula in northwestern Russia. These plants are classified in the broomrape family Orobanchaceae (following major rearrangements of the order Lamiales starting around 2001; sources which do not follow these reclassifications may place them in the Scrophulariaceae). They are hemiparasitic on the roots of grasses and forbs. The generic name honors Spanish botanist Domingo Castillejo. Ecology ''Castilleja'' species are eaten by the larvae of some lepidopteran species, including '' Schinia cupes'' (which has been recorded on ''C. exserta'') and ''Schinia pulchripennis'' (which feeds exclusively on ''C. exserta''), and checkerspot butterflies, such as ''Euphydryas'' species.

Echeveria
''Echeveria'' is a large genus of flowering plants in the family Crassulaceae, native to semi-desert areas of Central America, Mexico and northwestern South America. Description Plants may be evergreen or deciduous. Flowers on short stalks (cymes) arise from compact rosettes of succulent fleshy, often brightly coloured leaves. Species are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes. Often numerous offsets are produced, and are commonly known as "hen and chicks", which can also refer to other genera, such as ''Sempervivum'', that are significantly different from ''Echeveria''. Many species of ''Echeveria'' serve important environmental roles, such as those of host plants for butterflies. For example, the butterfly ''Callophrys xami'' uses several species of ''Echeveria'', such as ''Echevelia gibbiflora'', for suitable host plants. Even more, these plants are integral to the oviposition process of ''C. xami'' and some other b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Espeletia
''Espeletia'', commonly known as 'frailejones' ("big monks"), is a genus of perennial subshrubs, in the family Asteraceae. The genus, which is native mainly to Colombia, Venezuela and Ecuador, was first formally described in 1808. The genus was named after the viceroy of New Granada, José Manuel de Ezpeleta. The plants live at high altitude in páramo ecosystems. The trunk is thick, with succulent hairy leaves disposed in a dense spiral pattern. Marcescent leaves help protect the plants from cold. The flowers are usually yellow, similar to daisies. Some members of the genus exhibit a caulirosulate growth habit. The frailejón plant is endangered due to destruction of the páramo for agricultural purposes, especially potato crops. This activity continues, despite the Colombian government declaring it illegal. Since about 2010 the plants have also come under attack by beetle larvae, a moth and a fungus, some new to science but suspected to be related to climate change which al ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks.
