Costus Curvibracteatus
''Costus curvibracteatus'' is a tropical rhizomatous perennial native to Costa Rica and Panama. Taxonomy The first description of ''Costus curvibracteatus'' as a species was published by the Dutch botanist Paul Maas in 1976 in the ''Acta Botanica Neerlandica''. The article, 'Notes on New World Zingiberaceae', described 12 new species in the genus ''Costus''. The following year, Maas published a monograph on the Zingiberaceae, clearing up some taxonomic confusion and expanding descriptions, including that for ''C. curvibracteatus''. In this and other early works, the genus ''Costus'' is placed in the family Zingiberaceae, subfamily Costoideae. Following further classification contributions by botanist W. John Kress, the spiral gingers were recognised as a sister clade to the Zingiberaceae and moved to the family Costaceae, as originally suggested by the Japanese botanist Takenoshin Nakai in 1941.

Paulus Johannes Maria Maas
Paulus Johannes Maria "Paul" Maas (born 27 February 1939, in Arnhem) is a botanist from the Netherlands and a specialist in the flora of the neotropics. Maas has identified and named about two hundred fifty plants from the Burmanniaceae, the Costus Family ( Costaceae), the Gentian Family (Gentianaceae), the Bloodwort Family ( Haemodoraceae), the Banana Family (Musaceae), the Olacaceae, the Triuridaceae, and the Ginger Family (Zingiberaceae). The Annonaceae and saprotrophic plants from the neotropics, such as the Burmanniaceae, are two major areas of research. Maas has also worked with the genus '' Canna'' (Cannaceae) and has published floristic treatments of this group for the Guianas (Maas 1985) and Ecuador (Maas & Maas 1988). In 2008, he was honoured when botanists Mols, Kessler & Rogstad published a genus of flowering plants from Indo-China, belonging to the family Annonaceae The Annonaceae are a Family (biology), family of flowering plants consisting of trees, shrubs, or ...

Flora Of Panama
Panama is a country located in Central America, bordering both the Caribbean Sea and the Pacific Ocean, between Colombia and Costa Rica. Panama is located on the narrow and low Isthmus of Panama. This S-shaped isthmus is situated between 7° and 10° north latitude and 77° and 83° west longitude. Panama encompasses approximately . It is long, and between wide. Geology The Cocos and Nazca plates formed in the Miocene. The Panama microplate is made of oceanic crust basalt, similar to the basalt plateau at the bottom of the Caribbean Sea. The isthmus of Panama formed due to convergent tectonics of the eastern Pacific subduction zone, which created a magmatic arc extending from southern North America. The center of the isthmus, from Arenal Volcano in Costa Rica to El Valle volcano in Panama was uplifted during the subduction of the unusually thick Cocos Ridge oceanic crust, which also produced the four kilometer high Talamanca Range. The western edge of the Caribbean Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Costus
''Costus'' is a genus of herbaceous perennial plants in the family Costaceae, erected by Linnaeus in 1753. It is widespread through tropical and subtropical regions of Asia, Africa, and the Americas. ''Costus'' is often characterized and distinguished from relatives such as '' Zingiber'' (true ginger) by its spiraling stems. The genus as a whole is thus often called spiral gingers, but this can also refer to '' C. barbatus'' specifically. It is important not to confuse ''Costus scaber'', ''C. spectabilis'' etc. with the herb known by the common name " costus". '' Costus spectabilis'' is the floral emblem of Nigeria; its flowers are represented (erroneously in red instead of yellow color) on its coat of arms. '' Costus productus'' and '' Costus guanaiensis'' are among the species of ''Costus'' with edible flowers. Other ''Costus'' species' flowers have also been determined to be edible. Some ''Costus'' species have traditional medicinal and veterinary uses. For example, in T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

Ellipsoid
An ellipsoid is a surface that can be obtained from a sphere by deforming it by means of directional Scaling (geometry), scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a Surface (mathematics), surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar Cross section (geometry), cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is Bounded set, bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular Rotational symmetry, axes of symmetry which intersect at a Central symmetry, center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal ax ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zingiber Officinale
Ginger (''Zingiber officinale'') is a flowering plant whose rhizome, ginger root or ginger, is widely used as a spice and a folk medicine. It is an herbaceous perennial that grows annual pseudostems (false stems made of the rolled bases of leaves) about one meter tall, bearing narrow leaf blades. The inflorescences bear flowers having pale yellow petals with purple edges, and arise directly from the rhizome on separate shoots. Ginger is in the family Zingiberaceae, which also includes turmeric (''Curcuma longa''), cardamom (''Elettaria cardamomum''), and galangal. Ginger originated in Maritime Southeast Asia and was likely domesticated first by the Austronesian peoples. It was transported with them throughout the Indo-Pacific during the Austronesian expansion ( BP), reaching as far as Hawaii. Ginger is one of the first spices to have been exported from Asia, arriving in Europe with the spice trade, and was used by ancient Greeks and Romans. The distantly related dicots in ...

Rhizomes
In botany and dendrology, a rhizome ( ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. Rhizomes have nodes and internodes and auxiliary buds. Roots do not have nodes and internodes and have a root cap terminating their ends. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stolon is similar to a rhizome, but stolon sprouts from an existing stem having long internodes and generating new shoots at the ends, they are often also called runners such as in the strawberry plant. A stem tuber is a thickened part of a rhizome or sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae. Poaceae and Cyperaceae The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs. The membranous ligule can be very short 1–2 mm ( Kentucky bluegrass, ''Poa pratensis'') to very long 10–20 mm ( Johnson grass, ''Sorghum halepense''), it can also ...
