Heptapleurum Actinophyllum
''Heptapleurum actinophyllum'' (formerly ''Schefflera actinophylla'') is a tree in the family Araliaceae. It is native to tropical rainforests and gallery forests in northern and northeastern Queensland coasts and the Northern Territory of Australia, as well as New Guinea and Java. Common names include Australian umbrella tree, Queensland umbrella tree, octopus tree and amate. Description ''Heptapleurum actinophyllum'' is an evergreen tree growing to tall. It has palmately compound medium green leaves in groups of seven leaflets. It is usually multi-trunked, and the flowers develop at the top of the tree. It often grows as a hemiepiphyte on other rainforest trees. It produces racemes up to long containing up to 1,000 small red flowers. Flowering begins in early summer and typically continues for several months. The specific epithet ''actinophyllum'' means "with radiating leaves". Ecology The up to 1,000 flowers produced by the plant generate large amounts of nectar, attractin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, ''De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for observed dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Araliaceae
The Araliaceae are a family of flowering plants composed of about 43 genera and around 1500 species consisting of primarily woody plants and some herbaceous plants commonly called the ginseng family. The morphology of Araliaceae varies widely, but it is predominantly distinguishable based on its woody habit, tropical distribution, and the presence of simple umbels. There are numerous plants of economic importance. Some genera, such as ''Hedera'' (the ivies), '' Fatsia'' (Japanese aralias) and '' Heptapleurum'' (formerly ''Schefflera'', the umbrella trees), are used as ornamental foliage plants. The family also includes '' Panax ginseng'', the root of which is ginseng, used in traditional Chinese medicine. Overview The morphology of Araliaceae varies widely. Many studies have found that there is no unifying characteristic capable of classifying the family. In general, Araliaceae species have large, usually alternate leaves, often with aromatic ethereal oils, five-petaled fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malesia
Malesia is a biogeographical region straddling the Equator and the boundaries of the Indomalayan and Australasian realms. It is a phytogeographical floristic region in the Paleotropical kingdom. It was first recognized as a distinct region in 1857 by Heinrich Zollinger, a Swiss botanist and explorer. The precise boundaries used to define Malesia vary. The broadly defined area used in '' Flora Malesiana'' consists of the countries of Malaysia, Singapore, Indonesia, Brunei, the Philippines, Timor-Leste and Papua New Guinea. The original definition by the World Geographical Scheme for Recording Plant Distributions (WGSRPD) covered a similar area, but New Guinea and some offshore islands were split off as Papuasia in its 2001 version. Floristic region Malesia was first recognized as a distinct floristic region in 1857 by Heinrich Zollinger, a Swiss botanist and explorer. In 1948 and 1950, Cornelius G. G. J. van Steenis developed the idea of Malesia, and put forward plans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papuasia
Papuasia is a Level 2 botanical region defined in the World Geographical Scheme for Recording Plant Distributions (WGSRPD). It lies in the southwestern Pacific Ocean, in the Melanesia ecoregion of Oceania and Tropical Asia. It comprises the following geographic and political entities: * Aru Islands (Indonesia; treated as part of Western New Guinea in the Scheme) * New Guinea ** Papua New Guinea ** Western New Guinea (Indonesia) * Solomon Islands (archipelago) ** Bougainville ** Solomon Islands Solomon Islands, also known simply as the Solomons,John Prados, ''Islands of Destiny'', Dutton Caliber, 2012, p,20 and passim is an island country consisting of six major islands and over 1000 smaller islands in Melanesia, part of Oceania, t ...

Schefflera
''Schefflera'' is a genus of flowering plants in the family Araliaceae with 13 species native to New Zealand and some Pacific islands. The genus is named in honor of , physician and botanist of Gdańsk, and later of Warsaw, who contributed plants to for Reyger's book, ''Tentamen Florae Gedanensis''. Taxonomy The circumscription of the genus has varied greatly. Phylogenetic studies have shown that the widely used broad circumscription was polyphyletic, so most of its hundreds of species have been reassigned to other genera. Molecular analyses have recovered five polyphyletic clades of ''Schefflera'', all of which are geographically isolated from one another yet share similar traits indicating parallel evolution. These clades have been split into separate genera, primarily along geographical lines, with ''Schefflera'' now consisting of thirteen species restricted to New Zealand and some Pacific islands. The houseplant popularly known as "Schefflera" is now '' Heptapleurum arbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
