Lysiana Exocarpi
''Lysiana exocarpi'', commonly known as harlequin mistletoe, is a species of Parasitic plant, hemiparasitic shrub, Endemism, endemic to Australia. It is in the Gondwanan family Loranthaceae and is probably the most Derived trait, derived genus of that family with 12 pairs of chromosomes. The Loranthaceae is the most diverse family in the Mistletoes, mistletoe group with over 900 species worldwide and including the best known species in Australia. Mistletoes are notable for their relationships with other species. In an early reference to the group in Australia Allan Cunningham (botanist), Allan Cunningham explorer and first Director of the Royal Botanic Gardens, Sydney, wrote in 1817: "The Bastard Box is frequently much encumbered with the twining adhering ''Loranthus aurantiacus'' (box mistletoe) which 'Scorning the soil, aloft she springs, Shakes her red plumes and claps her golden wings'." Description Spreading to shrub, Glabrousness, glabrous; no external runners. Leaves fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Hermann Behr
Hans Hermann Behr (August 18, 1818, Köthen (Anhalt), Köthen – March 6, 1904, San Francisco) was a German Americans, German-American Physician, doctor, entomologist and botanist. At the time of his death, the ''San Francisco Chronicle'' reported that he was "reckoned among mental giants" and that he was "an authority of world-wide prominence" in many branches of science. Early life Behr came from a prominent family with connections to the administration of the principality of Köthen (also Koethen, Goethen or Colthen). He attended schools in Köthen and Zerbst where he studied Ancient Greek, Greek, Latin, Hebrew language, Hebrew and mathematics. As a boy he developed an interest in natural history, including collecting birds' eggs. In 1837 he began his study of medicine, first at the Martin Luther University of Halle-Wittenberg and later at the Humboldt University of Berlin where he graduated in 1843 as Doctor of Medicine. (In 1898, on his eightieth birthday, he was given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Moree, New South Wales
Moree is a town in Moree Plains Shire in northern New South Wales, Australia. It is located on the banks of the Mehi River, in the centre of the rich black-soil plains. The town is located at the junction of the Newell Highway and Gwydir Highway and can be reached by daily train and air services from Sydney. The Weraerai and Kamilaroi peoples are the earliest known inhabitants of the area, and the town's name is said to come from an Aboriginal word for "rising sun," "long spring," or "water hole". The town was settled by Europeans in the 1850s, and local Aboriginal residents were placed in missions, later Aboriginal reserves. The town, and in particular the Moree Baths and Swimming Pool, are known for being visited by the group of activists on the famous 1965 Freedom Ride, an historic trip through northern NSW led by Charles Perkins to bring media attention to discrimination against Indigenous Australians. Moree is a major agricultural centre, noted for its part in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exocarpos
''Exocarpos'' is a genus of flowering shrubs and small trees in the sandalwood family, Santalaceae. They are found throughout Southeast Asia, Australia and the Pacific Islands. They are semi-parasitic, requiring the roots of a host tree, a trait they share with many other members of the Santalaceae. In Australia, they are known as ''ballarts'', and several species are known as cherries. Within Australia, an identification key is available for New South Wales species, and for Victorian species.

Eremophila (plant)
''Eremophila'' is a genus of more than 260 species of plants in the figwort family, Scrophulariaceae all of which are endemic to mainland Australia. (One species, '' Eremophila debilis'' is thought to be a recent arrival in New Zealand). Eremophilas are widespread in the arid areas of Australia, especially Western Australia and range in size from low-growing shrubs to small trees. The petals are joined, at least at their bases, into a tube with the upper petals different in size and shape from the lower ones. Some species have common names including emu bush, poverty bush or fuchsia bush, reflecting the belief that emus eat the fruit, their arid environment or a superficial resemblance to the flowers of plants in the genus ''Fuchsia''. Description Eremophilas vary in size and habit from low, prostrate shrubs such as '' E. serpens'' to small trees in the case of '' E. bignoniiflora''. Leaf size and shape is also variable but the leaves are usually small and are often shiny or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casuarinaceae
The Casuarinaceae are a family of dicotyledonous flowering plants placed in the order Fagales, consisting of four genera and 91 species of trees and shrubs native to eastern Africa, Australia, Southeast Asia, Malesia, Papuasia, and the Pacific Islands. At one time, all species were placed in the genus ''Casuarina''. Lawrence Alexander Sidney Johnson separated out many of those species and renamed them into the new genera of ''Gymnostoma'' in 1980 and 1982, ''Allocasuarina'' in 1982, and ''Ceuthostoma'' in 1988, with some additional formal descriptions of new species in each other genus. At the time, it was somewhat controversial. The monophyly of these genera was later supported in a 2003 genetics study of the family. In the Wettstein system, this family was the only one placed in the order Verticillatae. Likewise, in the Engler, Cronquist, and Kubitzki systems, the Casuarinaceae were the only family placed in the order Casuarinales. Members of this family are characterized ...

Cassia (genus)
''Cassia'' is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae. Species are known commonly as cassias. Cassia is also the English common name of some species in the genus ''Cinnamomum'' of the family Lauraceae. Species of the genera '' Senna'' and ''Chamaecrista'' were previously included in ''Cassia''. ''Cassia'' now generally includes the largest species of the legume subtribe Cassiinae, usually mid-sized trees. Ecology ''Cassia'' species occur in a range of climates. Some can be utilized widely as ornamental plants. They have been used in reforestation projects, and species from desert climates can be used to prevent desertification. ''Cassia'' species are used as food plants by the caterpillars of many lepidopteran taxa. For example, the skipper ''Astraptes fulgerator'' and the pierids ''Catopsilia pomona'' and '' C. pyranthe'' are all seen on ''Cassia fistula''. The latter utilizes several other cassias, as well.

Amyema
''Amyema'' is a genus of semi- parasitic shrubs (mistletoes) which occur in Malesia and Australia. Etymology ''Amyema'' derives from the Greek: ''a'' (negative), and ''myeo'' (I initiate), referring to the genus being previously unrecognised. Description Hamilton & Barlow describe the haustorial structures of most Australian ''Amyemas'' as being ball-like, with some exceptions. Species There are approximately 90 species including the following: * '' Amyema arthrocaulis'' Barlow * ''Amyema artensis'' (Mont.) Dan. (indigenous to Upolu and Savai'i, known as ''tapuna''.) * '' Amyema benthamii'' (Blakely) Danser * ''Amyema betchei'' (Blakely) Danser * ''Amyema bifurcata'' (Benth.)

Alectryon (plant)
''Alectryon'' is a genus of about 30 species of trees and shrubs from the family Sapindaceae. They grow naturally across Australasia, Papuasia, Melanesia, western Polynesia, east Malesia and Southeast Asia, including across mainland Australia, especially diverse in eastern Queensland and New South Wales, the Torres Strait Islands, New Guinea, the Solomon Islands, New Caledonia, New Zealand, Vanuatu, Fiji, Samoa, Hawaii, Indonesia and the Philippines. They grow in a wide variety of natural habitats, from rainforests, gallery forests and coastal forests to arid savannas and heaths. Mainland Australia, especially the eastern Queensland and New South Wales rainforests and the monsoon tropics, harbours the global centre of ''Alectryon'' species diversity, having 15 species, 12 of them endemic to Australia. In the continent of, combined New Guinea including Papua New Guinea and West Papua, Australia and all of their continental islands, including the Torres Strait Islands, known collec ...

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitic
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obcordate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
