Schoepfia Multiflora
''Schoepfia multiflora'' is a species of flowering plant in the Schoepfiaceae family. It is a smallish tree, growing six to eight metres tall, exceptionally to ten metres. It is endemic to Jamaica, where it grows on rocky limestone in the woodlands of the central region. ''Schoepfia multiflora'' was first described as a new species by Ignatz Urban in the 1907 volume of the ''Symbolae Antillanae''. In the 1984 key by Hermann Otto Sleumer, ''Schoepfia multiflora'', ''S. harrisii'' and ''S. vacciniifolia'' are the only American '' Schoepfia'' species which have some or all flowers possessing tiny pedicels - all other species have sessile flowers which sit directly on top of the short peduncles. ''S. harrisii'' is also a Jamaican endemic, whereas ''S. vacciniifolia'' is a species from Central America.

Ignatz Urban
Ignatz Urban (7 January 1848 – 7 January 1931) was a German botanist. He is known for his contributions to the flora of the Caribbean and Brazil, and for his work as curator of the Berlin Botanical Garden. Born the son of a brewer, Urban showed an interest in botany as an undergraduate. He pursued further study at the University of Bonn and later at the University of Berlin where he gained a doctorate in 1873. Urban was appointed by A. W. Eichler to run the Berlin Botanical Garden and supervised its move to Dahlem. He also worked as Eichler's assistant on the ''Flora Brasiliensis'', later succeeding him as editor. In 1884 Urban began working with Leopold Krug on his Puerto Rican collections, a collaboration would later produce the nine-volume '' Symbolae Antillanae'', one of his most important contributions, and his 30-part ''Sertum Antillanum''. Urban's herbarium, estimated to include 80,000 or more sheets, was destroyed when the Berlin Herbarium was bombed in 1943 ...

Identification Key
In biology, an identification key, taxonomic key, or biological key is a printed or computer-aided device that aids the identification of biological entities, such as plants, animals, fossils, microorganisms, and pollen grains. Identification keys are also used in many other scientific and technical fields to identify various kinds of entities, such as diseases, soil types, minerals, or archaeological and anthropological artifacts. Traditionally identification keys have most commonly taken the form of single-access keys. These work by offering a fixed sequence of ''identification steps'', each with multiple alternatives, the choice of which determines the next step. If each step has only two alternatives, the key is said to be dichotomous, else it is polytomous. Modern multi-access or ''interactive keys'' allow the user to freely choose the identification steps and their order. At each step, the user must answer a question about one or more features (''characters'') of the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle.

Sessile (botany)
In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus ''Trillium'' is partitioned into two subgenera, the sessile-flowered trilliums (''Trillium'' subg. ''Sessilium'') and the pedicellate-flowered trilliums. Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel Pedicle or pedicel may refer to: Human anatomy *Pedicle of vertebral arch, the segment between the transvers ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

Schoepfia
''Schoepfia'' is a genus of small hemiparasitic trees, flowering plants belonging to the family Schoepfiaceae. The genus has long been placed in the Olacaceae family. Description Plants in this genus are small trees or shrubs which exhibit heterostyly - individuals can have both often cylindrical brachystylous (short styled) flowers and somewhat bell-shaped dolichostylous (longer styled) flowers. In most plants where heterostyly occurs, there is a sexual differentiation between flower types, the brachystylous flowers being functionally male, or one type of flower is cleistogamous or self-fertile. In ''Schoepfia'' species both flowers are bisexual and can form fruit, the reason for two flower forms is mysterious. The flowers are fragrant and small. They arise from a short peduncle which grows from the leaf axils of a stem. The peduncle is subtended by persistent, imbricate perular bracts. The flower is subtended by a three-lobed epicalyx, it is composed of a bract and two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schoepfia Harrisii
''Schoepfia harrisii'' is a species of flowering plant in the Schoepfiaceae family. It is a small tree or shrub, growing two to five metres tall. It is Endemism, endemic to Jamaica, where it is only known to occur in the Parishes of Jamaica, parishes of Trelawny Parish, Trelawny and Clarendon Parish, Jamaica, Clarendon, in what is known as Cockpit Country, a region of many steep, rounded, limestone hills, shaped like an egg-carton. Here it grows on crags in moist woodland, between 600 and 900m in elevation. Description It is a small tree or large shrub, growing two to five metres tall. In Hermann Otto Sleumer's 1984 monograph on the Neotropical species of ''Schoepfia'' he writes that it can exceptionally grow to ten metres, however he may have been confusing the issue with data garnered from a specimen of Schoepfia obovata, ''S. obovata'', a species which was first discovered to grow on the island in 1982, when it was found that an earlier found specimen of ''S. obovata'' had been ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
