Exocarpos Humifusus
''Exocarpos humifusus'', also known as mountain native-cherry, is a small shrub member of the family Santalaceae, all of which are hemiparasites. ''Exocarpos humifusus'' is a dwarfish and sprawling shrub with woody stems, and small dry fruits that grow atop a fleshy red stalk, hence the common name of native-cherry. Description ''Exocarpos humifusus'' is a rigid, woody dwarf shrub with branches prostrate and spreading over the ground and rocks. The stems are dark yellow-green tinged with red, and are ribbed with rounded edges. The leaves are triangular and scale shaped, about long, arranged alternately along the stem. The flowers are generally 4 parted, approximately in diameter and grow in bunches of 2-3 on a short stalk at the end of a stem. The fruit is a small greenish-black drupe or nut in length, that grows atop a fleshy receptacle. When mature the receptacle of the fruit is dark red fleshy, juicy and edible, attracting animals as distributors. Habitat and distribution ...

Santalaceae
The Santalaceae, sandalwoods, are a widely distributed family of flowering plants (including small trees, shrubs, perennial herbs, and epiphytic climbersHewson & George t al.br>''Santalaceae'' taxonomy, 1984, pp. 191-194.) which, like other members of Santalales, are partially parasitic on other plants. Its flowers are bisexual or, by abortion ("flower drop"), unisexual.Pilger, R''Santalaceae''(with 17 figures). R. Br. Prodr. Fl. Nov. Holl. (1810) 350, pp. 1-45. Modern treatments of the Santalaceae include the family Viscaceae (mistletoes), previously considered distinct. The APG II system of 2003 recognises the family and assigns it to the order Santalales in the clade core eudicots. However, the circumscription by APG is much wider than accepted by previous classifications, including the plants earlier treated in families Eremolepidaceae and Viscaceae. It includes about 1,000 species in 43 genera. Many have reported traditional and cultural uses, including as medicine. Genera ...

Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heath
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feldmark
Feldmark, also spelt fjaeldmark (), is a plant community characteristic of sites where plant growth is severely restricted by extremes of cold and exposure to wind, typical of alpine tundra and subantarctic environments. Description Feldmark plant communities are characterised by scattered dwarf and prostrate plants, up to about in height, often with a mat or cushion habit, among patches of bare ground and exposed rock. Distribution Feldmark occurs in the least favourable situations for plant growth, including late-lying snowdrift areas on leeward slopes and cold, highly wind-exposed ridges. Because feldmark species are adapted to cold bare ground, some are able to colonise areas of severe erosion where the topsoil has been removed, leaving only a surface of broken rock or stones.. In areas with strong prevailing winds, expansion through layering on the sheltered sides of plants means that they may grow preferentially on the protected sides and gradually move downwind across th ...

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.
