Alsophila Annae
''Gymnosphaera annae'', synonyms ''Alsophila annae'' and ''Cyathea annae'', is a species of tree fern native Sulawesi and to Ambon in the Maluku Islands, where it grows in forest from sea level to about 650 m. The erect trunk is slender and may be as tall as 3 m. Fronds are bipinnate and 1–2 m in length. Characteristically of this species, the final pair of pinnae are usually reduced and occur towards the base of the stipe. The stipe is dark, slender and covered with scattered scales. These are dark, glossy and have a pale dull margin. Fertile pinnules are normally short-lobed. Sori lack indusia and occur two to four per pinnule lobe. The plant was first described as ''Alsophila annae'' from a plant cultivated at the Bogor Botanic Gardens in Java. The specific epithet ''annae'' commemorates Anna Smith (wife of Johannes Jacobus Smith Johannes Jacobus Smith (Antwerp 29 June 1867 – Oegstgeest 14 January 1947) (sometimes written as Joannes Jacobus Smith) was a Dutch bota ...

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 ...

Sorus
A sorus (: sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. A coenosorus (: coenosori) is a compound sorus composed of multiple, fused sori. Etymology This Neo-Latin word is from Ancient Greek σωρός (''sōrós'' 'stack, pile, heap'). Structure In lichens and other fungi, the sorus is surrounded by an external layer. In some red algae, it may take the form of depression into the thallus. In ferns, the sori form a yellowish or brownish mass on the edge or underside of a fertile frond. In some species, they are protected during development by a scale or film of tissue called the indusium (: indusia), which forms an umbrella-like cover. Life cycle significance Sori occur on the sporophyte generation, the sporangia within producing haploid meiospores. As the sporangia mature, the indusium shrivels so that spore release is unimpeded. The sporangia then burst and release the spores. As an aid to identification The shape, arrang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Maluku Islands
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 of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Gymnosphaera
''Gymnosphaera'' is a genus of tree ferns in family Cyatheaceae. Taxonomy The genus was originally described by Carl Ludwig Blume in 1828. It was frequently treated by later authors as a synonym of ''Cyathea'' or '' Alsophila''. In the Pteridophyte Phylogeny Group The Pteridophyte Phylogeny Group (PPG) is an informal international group of systematic botanists who collaborate to establish on the classification of pteridophytes ( lycophytes and ferns) that reflects knowledge about plant relationships discove ... classification of 2016 (PPG I), ''Gymnosphaera'' was left as a synonym of ''Alsophila'', as evidence to support its reliable separation was lacking. More recently, Shi-Yong Dong and collaborators proposed the revival and recircumscription of the genus based on additional phylogenetic evidence, an act subsequently accepted by other tree fern workers. Phylogeny , the following species are accepted in the genus as currently circumscribed by the Checklist of Ferns and Lycop ...

Johannes Jacobus Smith
Johannes Jacobus Smith (Antwerp 29 June 1867 – Oegstgeest 14 January 1947) (sometimes written as Joannes Jacobus Smith) was a Dutch botanist who, between years 1905 to 1924, crossed the islands of the Dutch East Indies (mainly Java), collecting specimens of plants and describing and cataloguing the flora of these islands. The standard botanical author abbreviation J.J.Sm. is applied to plants described by J.J. Smith. The description of the flowers of the western half of New Guinea (then a Dutch territory) is largely based on his work. He was, next to Rudolf Schlechter, the most prolific author on New Guinea orchids. He also described numerous plants from other families, such as Ericaceae and Euphorbiaceae. Biography Smith was born in Antwerp where his father worked in the postal department. The family moved to Utrecht in 1872 and to Amsterdam in 1875. He took an interest in growing plants and keeping animals. One of his secondary school teachers was Jan Costerus who advised hi ...

Epithet
An epithet (, ), also a byname, is a descriptive term (word or phrase) commonly accompanying or occurring in place of the name of a real or fictitious person, place, or thing. It is usually literally descriptive, as in Alfred the Great, Suleiman the Magnificent, Richard the Lionheart, and Ladislaus the Short, or allusive, as in Edward the Confessor, William the Conqueror, Æthelred the Unready, John Lackland, Mehmed the Conqueror and Bloody Mary. The word ''epithet'' also may refer to an abusive, defamatory, or derogatory word or phrase. This use is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler noted in 1926 that "''epithet'' is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes attached to a person's name or appear in place of their name, as what might be described as a glorified nickname or sobriquet, and for this reason some linguists have argued that they should be c ...

Java
Java is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea (a part of Pacific Ocean) to the north. With a population of 156.9 million people (including Madura) in mid 2024, projected to rise to 158 million at mid 2025, Java is the world's List of islands by population, most populous island, home to approximately 55.7% of the Demographics of Indonesia, Indonesian population (only approximately 44.3% of Indonesian population live outside Java). Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the History of Indonesia, Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally.

Bogor Botanic Gardens
The Bogor Botanical Gardens () is a botanical garden located in Bogor, Indonesia, 60 km south of central Jakarta. It is currently operated by the National Research and Innovation Agency. The garden is located in the city center and adjoin the presidential palace compound of Istana Bogor. It covers an area of and contains 13,983 different kinds of trees and plants of various origin. The geographic position of Bogor means it rains almost daily, even in the dry season. This makes the garden an advantageous location for the cultivation of tropical plants. Founded in 1817 by the order of the government of the Dutch East Indies, the garden thrived under the leadership of many renowned botanists including Johannes Elias Teijsmann, Rudolph Herman Christiaan Carel Scheffer, and Melchior Treub. Since its foundation, the Bogor botanical garden has served as a major research center for agriculture and horticulture. It is the oldest botanical garden in Southeast Asia. History Backgro ...

Pinnule
A leaflet (occasionally called foliole) in botany is a leaf-like part of a compound leaf. Though it resembles an entire leaf, a leaflet is not borne on a main plant stem or branch, as a leaf is, but rather on a petiole or a branch of the leaf. Compound leaves are common in many plant families and they differ widely in morphology. The two main classes of compound leaf morphology are palmate and pinnate. For example, a ''hemp'' plant has palmate compound leaves, whereas some species of ''Acacia'' have pinnate leaves. The ultimate free division (or leaflet) of a compound leaf, or a pinnate subdivision of a multipinnate leaf is called a pinnule or pinnula.

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stipe (botany)
In botany, a stipe is a stalk that supports some other structure. The precise meaning is different depending on which taxonomic group is being described. file:Helicteres-Yucatán-Flowers.jpg, The long stipe of a '' Helicteres'' flower. file:Helicteres-Yucatán-Fruits.jpg, remains as each flower forms a fruit. In the case of ferns, the stipe is only the petiole from the rootstock to the beginning of the leaf tissue, or lamina. The continuation of the structure within the lamina is then termed a rachis. In flowering plants, the term is often used in reference to a stalk that sometimes supports a flower's ovary. In orchids, the stipe or caudicle is the stalk-like support of the pollinia. It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak). A stipe is also a structure found in organisms that are studied by botanists but that are no longer classified as plants. It may be the stem-like part of the thallus of a ...
