Campynema Lineare
''Campynema'' is a genus in the family Campynemataceae first described in 1805. It contains only one known species (monotypic), ''Campynema lineare'', endemic to the island of Tasmania in Australia. Its closest relative is '' Campynemanthe'', endemic to New Caledonia, sole other genus of the family. ''Campynema lineare'' ''C. lineare'', also known as the green mountain lily, is a small inconspicuous erect herb that grows to 15–30 cm in height. Its leaves consist of a single, curved basal leaf, with smaller leaves ascending up the flower stem. It is most distinguishable by its striking green flower, which blooms in summer. The flower is usually solitary, with 6 green tepals, sometimes with a burgundy tinge and developing brown edges with age, lacking apparent nectaries. The anthers are dorsifixed, styluli are free but thickened and contiguous below. The seeds are numerous and are flattened, sometimes almost discoid, with a spongy outer coat. It is a geophyte, and its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geophyte
A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Plants that have an underground storage organ are called geophytes in the Raunkiær plant life-form classification system.; reprinted (1977) in ''History of ecology'' series, New York: Arno Press, Storage organs often, but not always, act as perennating organs which enable plants to survive adverse conditions (such as cold, excessive heat, lack of light or drought). Relationship to perennating organ Storage organs may act as perennating organs ('perennating' as in perennial, meaning "through the year", used in the sense of continuing beyond the year and in due course lasting for multiple years). These are used by plants to survive adverse periods in the plant's life-cycle (e.g. caused by cold, excessive heat, lack of light or drought). During these per ...

Endemic Flora Of Tasmania
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Tasmanian Cushion Plants
Tasmanian cushion plants are low growing, highly compact, woody, spreading mats that can grow up to 3 m in diameter, located mainly on the island of Tasmania. These mats are made up of tightly packed stems that grow at the same rate so that no apical rosettes protrude above the rest. The term cushion plant refers to a characteristic growth habit adopted by various species from a range of families to adapt to alpine and subalpine environments and areas of high latitude. They are adapted to grow in low nutrient areas and typically have deep taproots. Cushion plants are very slow growing and do not grow high above ground; mounds typically remain under 30 cm high. Underneath the living surface of the cushion, the plants either allow dead leaves to persist or produce non-photosynthetic material, resulting in an insulating effect. Floristics of Tasmanian cushion plant community Six families, including seven species, of cushion plants occur in Tasmania, and one additional family and ...
