Peraxilla Colensoi
''Peraxilla colensoi'', the scarlet mistletoe, is a shrubby parasitic plant composed of broad, leathery leaves that grow up to 8 cm long and have a red edge. The common name is derived from the scarlet petals of the plant that bloom every October to January. These mistletoes are parasitic plants whose seeds attach themselves to host plants. The most common host for these plants is the silver beech. The plant can grow up to 3 meters tall and are often located in low altitudes throughout the North and South Islands of New Zealand. Description This is a parasitic plant and relies on its host to grow and survive on. Individuals of this species are shrubs up to 3m long and will further out to branches on its host. It has glossy green paired leaves and red tubular flowers. The fruit produced is a small, round yellow color and the leathery leaves of the shrub will fall and cover the forest floor. Distribution ''Peraxilla colensoi'' naturally occurs to grow on other trees in New Zealan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peraxilla Tetrapetala
''Peraxilla tetrapetala'', or red mistletoe, is a parasitic plant in the family Loranthaceae, endemic to New Zealand and found on both the North and South Islands. The Māori names for the plant are pikirangi, pirirangi and roeroe. It is a shrub up to one metre tall with glabrous leaves. The flowers are 4–5 mm long, bright red to orange in colour which split open to the base. Red mistletoe mainly parasitises ''Quintinia'' and ''Nothofagus'' species. Its principal host is the black/mountain beech (''Nothofagus solandri'' complex). However, north of latitude 38°S this species utilises tawheowheo (''Quintinia serrata''), and in the far north has been found on pohutukawa (''Metrosideros excelsa''), puriri (''Vitex lucens'') and towai (''Weinmannia sylvicola''), and hence, is the most widely distributed beech mistletoe. ''P. tetrapetala'' is hermaphroditic, self-compatible, and is both bird-pollinated and bird-dispersed, yet has an explosive bud-opening mechanism. It is tho ...

Loranthaceae
Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are ''Nuytsia floribunda'' (the Western Australian Christmas tree), ''Atkinsonia ligustrina'' (from the Blue Mountains of Australia), and '' Gaiadendron punctatum'' (from Central/South America.) Loranthaceae are primarily xylem parasites, but their haustoria may sometimes tap the phloem, while '' Tristerix aphyllus'' is almost holoparasitic. For a more complete description of the Australian Loranthaceae, seFlora of Australia online, for the Malesian Loranthaceae seFlora of Malesia Originally, Loranthaceae contained all mistletoe species, but the mistletoes of Europe and North America (''Viscum'', ''Arceuthobium'', and ''Phoradendron'') belong to the family Santalaceae. The APG II system 2003 assigns the family to the order Santalales in the clade core eudicots. Phylog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippe Édouard Léon Van Tieghem
Philippe Édouard Léon Van Tieghem (; 19 April 1839 – 28 April 1914) was a French botanist born in Baillleul in the département of Nord. He was one of the best known French botanists of the latter nineteenth century. Life Van Tieghem's father was a textile merchant who died of yellow fever in Martinique before he was born, and his mother shortly thereafter. One of five children, he obtained his ''baccalauréat'' in 1856, and continued his studies at the École Normale Supérieure, where after receiving agrégation, he worked in the laboratory of Louis Pasteur (1822–1895). Here he performed research involving the cultivation of mushrooms. He is credited with creation of the eponymous "Van Tieghem cell", a device mounted on a microscope slide that allows for observing the development of a fungus' mycelium. In 1864 he earned his doctorate in physical sciences with a thesis titled ''Recherches sur la fermentation de l'urée et de l'acide hippurique'', and two years later ob ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
