Manekia Incurva
''Manekia'' is a genus of flowering plants in the family Piperaceae. It is distributed across disjunct areas in the southern Atlantics Forests of Brazil, the Guiana shield in Venezuela, the Andean regions of Colombia, Ecuador and Peru, the Caribbean coast of Nicaragua, Costa Rica and Panama, and the Greater and Lesser Antilles. It thrives in karst areas, and in humid, premontane or montane forests from sea level to . The name ''Manekia'' is a taxonomic anagram derived from the name of the genus '' Ekmania''. The latter name is a taxonomic patronym honoring the Swedish botanist Erik Leonard Ekman. Description ''Manekia'' members are characterized by scandent or lianescent habits and by short sympodial branches holding the spikes. Flowers possess four stamens, four-carpellate pistils with four or five stigmas. Berries are fully or partially immersed in the rachis. When compared to other Piperaceae genera, the ecology of ''Manekia'' appears rather distinct, with plants invad ...

Patronym (taxonomy)
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type (biology), type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9&nbs ...

Peperomia
''Peperomia'' is one of the two large genera of the family Piperaceae. It is estimated that there are at least over 1,000 species, occurring in all tropical and subtropical regions of the world. They are concentrated in South and Central America, but may also be found in southern North America, the Caribbean islands, Africa, Oceania, and southern and eastern parts of Asia. The exact number of species is difficult to determine, as some plants have been recorded several times with different names, and new species continue to be discovered. Peperomias have adapted to many different environments and their appearances vary greatly. Some are epiphytes (growing on other plants) or lithophytes (growing on rock or in rock crevices), and many are xerophytes (drought-tolerant, with thick succulent structures to save water) or possess underground tubers ( geophytes). Most species are compact perennial shrubs or vines. Some Peperomias have thick, waxy, succulent leaves and stems; still, others ...

Piper (plant)
''Piper'', the pepper plants or pepper vines, is an economically and ecologically important genus in the family Piperaceae. It contains about 1,000–2,000 species of shrubs, herbs, and lianas, many of which are dominant species in their native habitat. The diversification of this taxon is of interest to understanding the evolution of plants. Pepper plants belong to the magnoliids, which are angiosperms but neither monocots nor eudicots. Their family, Piperaceae, is most closely related to the lizardtail family ( Saururaceae), which in fact generally look like smaller, more delicate and amphibious pepper plants. Both families have characteristic tail-shaped inflorescences covered in tiny flowers. A somewhat less close relative is the pipevine family ( Aristolochiaceae). A well-known and very close relative – being also part of the Piperaceae – are the radiator plants of the genus '' Peperomia''. The scientific name ''Piper'' and the common name "pepper" are derived f ...

Zippelia
''Zippelia begoniifolia'' is the only species of the monotypic genus ''Zippelia'', a genus of plants in the Piperaceae, the same botanical family as that of black pepper. The species has also been spelled as ''Z. begoniaefolia''. It is an erect, ascending, perennial herb with leaves of in length. It occurs in Borneo, Cambodia, southern-central and southeast mainland China as well as Hainan, Java, Laos, Peninsular Malaysia, the Philippines, Sumatra, Thailand and Vietnam. The generic epithet commemorates Alexander Zippelius. Zippelius was a horticulturist and early collector of plants in Java and other islands of the region. The genus name ''Zippelia'' has a confused taxonomic history, also having been used to place the parasitic plants now classified in the genus '' Rhizanthes'' by Ludwig Reichenbach Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist, ornithologist and illustrator. It was he who first requested Leopold and Rudolf Bl ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant community, plant cropping or crop, formed by the collection of individual Crown (botany), plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, Arboreal, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, Ecological resilience, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants. Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted ...

Sympodial Branching
In botany, sympodial growth is a bifurcating branching pattern where one branch develops more strongly than the other, resulting in the stronger branches forming the primary shoot and the weaker branches appearing laterally. A sympodium, also referred to as a sympode or pseudaxis, is the primary shoot, comprising the stronger branches, formed during sympodial growth. The pattern is similar to dichotomous branching; it is characterized by branching along stems or hyphae. Sympodial growth occurs when the apical meristem is terminated and growth is continued by one or more lateral meristems, which repeat the process. The apical meristem may be consumed to make an inflorescence or other determinate structure, or it may be aborted. Types If the sympodium is always formed on the same side of the branch bifurcation, e.g. always on the right side, the branching structure is called a helicoid cyme or bostryx. If the sympodium occurs alternately, e.g. on the right and then the left, ...

Lianescent
A liana is a long- stemmed woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. The word ''liana'' does not refer to a taxonomic grouping, but rather a habit of plant growth—much like ''tree'' or ''shrub''. It comes from standard French , itself from an Antilles French dialect word meaning to sheave. Ecology Lianas are characteristic of tropical moist broadleaf forests (especially seasonal forests), but may be found in temperate rainforests and temperate deciduous forests. There are also temperate lianas, for example the members of the ''Clematis'' or ''Vitis'' (wild grape) genera. Lianas can form bridges in the forest canopy, providing arboreal animals—including ants and many other invertebrates, lizards, rodents, sloths, monkeys, and lemurs—with paths through the forest. For example, in the Eastern tropical forests of Madagascar many lemurs achieve ...

Scandent
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 tissue, ...

Erik Leonard Ekman
Erik Leonard Ekman was a Swedish botanist and explorer. Biography Erik Leonard Ekman was born into a low-income household with five children on October 14, 1883. Due to economic difficulties, the family moved to the central-Swedish town of Jönköping when he was eleven and a half. Here, while at school, his passion for botanical collecting started. He was awarded a bachelor's degree in 1907 at Lund University in southern Sweden and was offered free passage on a ship to Argentina with a Swedish shipping company. He spent three months in Misiones collecting plants, aided greatly by the local Swedish colony. While there, he was offered a position as the Regnellian amanuensis at the Swedish Museum of Natural History in Stockholm, which he gladly accepted. He started his service at the museum in 1908. Thanks to financial support from the Regnell fund, he was able to travel widely through Europe and study with many of the prominent botanists of the time. Ekman presented his doctoral ...
