Negria
''Negria'' is a plant genus in the family Gesneriaceae. Its only species is ''Negria rhabdothamnoides'', commonly known as the pumpkin tree. It is related to '' Fieldia'' (syn. ''Lenbrassia'') and '' Depanthus''. Description The pumpkin tree grows to about 8 m in height. It has pale, corky bark and soft, brittle wood. The ovate to broadly elliptic leaves are 70–200 mm long and 45–100 mm wide; they have glossy upper surfaces and are pale and sparsely haired beneath. The flowers are large and orange with small red dots, appearing over summer from October to April. The fruit is a black, beaked capsule 15 mm long which holds numerous tiny, wind-dispersed seeds. Distribution and habitat The species is endemic to Australia's subtropical Lord Howe Island in the Tasman Sea The Tasman Sea ( Māori: ''Te Tai-o-Rēhua'', ) is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand.

Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhabdothamnus
''Rhabdothamnus solandri'' is a small shrub of the family Gesneriaceae endemic to New Zealand. It is the only plant of the genus ''Rhabdothamnus'', and the only member of Gesneriaceae native to New Zealand. Its common names are New Zealand gloxinia and, in the Māori language, , , and . The species is found throughout the North Island, less commonly in the southern part of the island, and its offshore islands, in a variety of locations such as forests, near streams, or on banks. It grows as a shrub up to 2 metres tall. It has distinctive trumpet-shaped flowers that are modest-sized at 2–2.5, and up to 4, centimetres long. The flowers are usually orange, but sometimes brick-red, yellow, purple or pink, and are longitudinally striped by 12–14, even up to 20, red or dark orange veins. It flowers year-round, peaking between October and February. The flowers are pollinated mainly by the bellbird, tui and stitchbird. The silvereye, which is a 19th-century immigrant to New Zeal ...

Gesneriaceae
Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World (almost all Didymocarpoideae) and the New World (most Gesnerioideae), with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants. Etymology The family name is based on the genus '' Gesneria'', which honours Swiss naturalist and humanist Conrad Gessner. Description Most species are herbaceous perennials or subshrubs but a few are woody shrubs or small trees. The phyllotaxy is usually opposite and decussate, but leaves have a spiral or alternate arrangement in some groups. As with other members of the Lamiales the flowers have a (usually) zygomorphic corolla whose petals are fused into a tube and there is no one character that separates a gesneriad from any other member of Lamiales. Gesneriads differ from related families o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gesnerioideae
The Gesnerioideae are a subfamily of plants in the family Gesneriaceae: based on the type genus ''Gesneria''. Although genera typically originate in the New World, some species have become widely distributed as ornamental plants. Description Gesnerioideae is one of two main subfamilies in the Gesneriaceae, the other being Didymocarpoideae. (The third subfamily, Sanangoideae, contains only the genus '' Sanango''.) Gesnerioideae seedlings have normal cotyledons of the same size and shape (isocotylous), whereas the cotyledons of Didymocarpoideae are usually, but not always, eventually different in size and shape (anisocotylous). Gesnerioideae flowers usually have four fertile stamens, rarely two or five. In other respects, Gesnerioideae species are very variable. The ovary may be superior, semi-inferior or inferior, and the fruit takes various forms. Taxonomy The original use of the name for the subfamily is attributed to Gilbert Thomas Burnett in 1835. Burnett divided his circu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferdinand Von Mueller
Baron Sir Ferdinand Jacob Heinrich von Mueller, (german: Müller; 30 June 1825 – 10 October 1896) was a German-Australian physician, geographer, and most notably, a botanist. He was appointed government botanist for the then colony of Victoria (Australia) by Governor Charles La Trobe in 1853, and later director of the Royal Botanic Gardens, Melbourne. He also founded the National Herbarium of Victoria. He named many Australian plants. Early life Mueller was born at Rostock, in the Grand Duchy of Mecklenburg-Schwerin. After the early death of his parents, Frederick and Louisa, his grandparents gave him a good education in Tönning, Schleswig. Apprenticed to a chemist at the age of 15, he passed his pharmaceutical examinations and studied botany under Professor Ernst Ferdinand Nolte (1791–1875) at Kiel University. In 1847, he received his degree of Doctor of Philosophy from Kiel for a thesis on the plants of the southern regions of Schleswig. Mueller's sister Bertha ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. 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 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. phylogenetic analysis should cl ...

Fieldia (plant)
''Fieldia'' is a genus of flowering plants in the family Gesneriaceae, native to New South Wales, Queensland and Victoria in Australia.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subtropical
The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical ( Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate ( Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau and in Da Lat of the Vietnamese Central Highlands. The six c ...
