Asteranthera
''Asteranthera'' is a monotypic plant genus in the family Gesneriaceae, native to the humid temperate forests of Argentina and Chile. The sole species in the genus, ''Asteranthera ovata'', is an evergreen scrambling vine A vine is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas, or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Da .... The plant has small rounded leaves with scalloped margins. The flowers are tubular and two-lipped, red with white markings. It blooms in the summer and can be grown as a climber or ground cover.

Gesneriaceae
Gesneriaceae, the gesneriad family, is a family (biology), family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World (almost all Didymocarpoideae) and the New World (most Gesnerioideae), with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants. Etymology The family name is based on the genus ''Gesneria'', which honours Switzerland, Swiss naturalist and humanism, humanist Conrad Gessner. Description Most species are herbaceous plant, herbaceous perennial plant, perennials or subshrubs but a few are woody shrubs or small trees. The phyllotaxy is usually opposite and decussate, but leaves have a spiral or alternate arrangement in some groups. As with other members of the Lamiales the flowers have a (usually) zygomorphic corolla whose petals are fused into a tube and there is no one character that separates a gesneriad from any o ...

Johannes Von Hanstein
Johannes Ludwig Emil Robert von Hanstein (15 May 1822 – 27 August 1880) was a German botanist who was a native of Potsdam. He attended classes at the ''Gärtnerlehranstalt'' (Institute of Horticulture) in Potsdam, and later studied sciences in Berlin, obtaining his doctorate in 1848. In 1855 he was a lecturer of botany at the University of Berlin, and six years later became curator of the royal herbarium. In 1865 he was appointed professor of botany at the University of Bonn and director of the botanical garden. Hanstein is remembered for studies in plant anatomy and morphology. In 1868 he introduced the " histogen theory" to explain shoot apex behaviour in plants. With his close friend, Nathanael Pringsheim (1823–1894), he conducted pioneer research on the fertilization process in ferns. The plant genus '' Hansteinia'' of the family Acanthaceae is named after him. Gallery File:Capsella bursa-pastoris, kiembol (Hanstein).jpg, ''Capsella bursa-pastoris'' drawing by Johann ...

Gesnerioideae
The Gesnerioideae are a subfamily of plants in the family Gesneriaceae: based on the type genus ''Gesneria''. Although genera typically originate in the New World, some species have become widely distributed as ornamental plants. Description Gesnerioideae is one of two main subfamilies in the Gesneriaceae, the other being Didymocarpoideae. (The third subfamily, Sanangoideae, contains only the genus ''Sanango''.) Gesnerioideae seedlings have normal cotyledons of the same size and shape (isocotylous), whereas the cotyledons of Didymocarpoideae are usually, but not always, eventually different in size and shape (anisocotylous). Gesnerioideae flowers usually have four fertile stamens, rarely two or five. In other respects, Gesnerioideae species are very variable. The Ovary (botany), ovary may be superior, semi-inferior or inferior, and the fruit takes various forms. Taxonomy The original use of the name for the subfamily is attributed to Gilbert Thomas Burnett in 1835. Burnett divide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Valdivian Temperate Forests
The Valdivian temperate forests (NT0404) is an ecoregion on the west coast of southern South America, in Chile and Argentina. It is part of the Neotropical realm. The forests are named after the city of Valdivia. The Valdivian temperate rainforests are characterized by their dense understories of bamboos, ferns, and for being mostly dominated by evergreen angiosperm trees with some deciduous specimens, though conifer trees are also common. Setting Temperate rain forests comprise a relatively narrow Chilean coastal strip, between the Pacific Ocean to the west and the southern Andes Mountains to the east, from roughly 37° to 48° south latitude. North of 42°, the Chilean Coast Range stretches on, with just the north–south running Chilean Central Valley between it and the Andes. South of 42°, the coast range continues as a chain of offshore islands (including Chiloé Island and the Chonos Archipelago), while the "Central Valley" is submerged and continues as the Gulf of Corc ...

Evergreen
In botany, an evergreen is a plant which has Leaf, foliage that remains green and functional throughout the year. This contrasts with deciduous plants, which lose their foliage completely during the winter or dry season. Consisting of many different species, the unique feature of evergreen plants lends itself to various environments and purposes. Evergreen species There are many different kinds of evergreen plants, including trees, shrubs, and vines. Evergreens include: * Most species of conifers (e.g., pine, Tsuga, hemlock, spruce, and fir), but not all (e.g., larch). * Live oak, holly, and "ancient" gymnosperms such as cycads * Many woody plants from frost-free climates * Rainforest trees * All eucalypts * Lycopodiopsida, Clubmosses and relatives * Most bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance: :''Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' ...

Vine
A vine is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas, or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Daydon (1928). ''A Glossary of Botanic Terms with their Derivation and Accent'', 4th ed. London: Gerald Duckworth & Co. In parts of the world, including the British Isles, the term "vine" usually applies exclusively to grapevines, while the term "climber" is used for all climbing plants. Growth forms Certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available. A vine displays a growth form based on very long stems. This has two purposes. A vine may use rock exposures, other plants, or other supports for growth rather than investing energy in a lot of supportive tissu ...

Flora Of The Valdivian Temperate Forests
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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 Metonymy () is a figure of speech in which a concept is referred to by the name of something associated with that thing or concept. For example, the word " suit" may refer to a person from groups commonly wearing business attire, such as sales ... of this goddess at the end of the sixteenth century.
