Argyroxiphium Grayanum
''Argyroxiphium grayanum'', commonly known as the greensword, is a species of flowering plant in the family Asteraceae, and a member of the silversword alliance, a group of over 50 species which are diverse in morphology and habitat but are genetically closely related. The silversword alliance provides a convincing natural case study in evolution by adaptive radiation, with the greensword representing one extreme of the genus' plasticity. Some ''Argyroxiphium'', including the well-known Haleakala and Mauna Kea silverswords, live in harsh alpine desert-like conditions of heat, sun, wind, and aridity, and are drought-adapted plants capable of storing water as a gel in leaf structures which are normally air pockets in other plants. However, ''A. grayanum'' is a bog plant adapted to very different conditions – excessive moisture, lack of regular sunlight, and cool temperatures, and its leaves are non-succulent like those of the related genus ''Dubautia''.

William Hillebrand
Wilhelm or William Hillebrand (November 13, 1821 – July 13, 1886) was a German physician. He practiced medicine in several different countries, including for over 20 years in the Hawaiian islands. In 1850, Hillebrand lived at what is now Foster Botanical Garden in Honolulu and gained acknowledgement as a botanist. Life and career Hillebrand was born on November 13, 1821, in Nieheim, Province of Westphalia, Prussia. His father was Judge Franz Josef Hillebrand, and mother Louise Pauline Konig. He studied medicine at Heidelberg and Berlin, and practiced at Paderborn. He sought a warmer climate to recover from a lung problem, (perhaps tuberculosis), first traveling to Australia in 1849, and then the Spanish East Indies, Philippines. Hillebrand then went to San Francisco and finally arrived in the Kingdom of Hawaii, Hawaii on December 22, 1850. He stayed for a little over 20 years and made significant contributions to local medical practice. He was able to speak the Hawaiian langu ...

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] |
Argyroxiphium
''Argyroxiphium'' is a small genus of plants in the family Asteraceae. Its members are known by the common names silversword or greensword due to their long, narrow leaves and the silvery hairs on some species. The silverswords belong to a larger Adaptive radiation, radiation of over 50 species, including the physically different genera ''Dubautia'' and ''Wilkesia''. This grouping is often referred to as the silversword alliance.[B. Baldwin. Age and Rate of Diversification of the Hawaiian Silversword Alliance (Compositae). 1998.] Botanist P. H. Raven referred to this radiation as "the best example of adaptive radiation in plants". Description Species in ''Argyroxiphium'' are Perennial plant, perennial, Rosette (botany), rosette-forming shrubs. They may consist of a single large rosette or a collection of several rosettes. In all ''Argyroxiphium'' species, long, narrow leaves contain interstitial gels hypothesized to function as water storage. For some species, leaves are cove ...

Common names for the species include Muir's tarplant,''Carlquistia muirii''. The Jepson eFlora 2013 Muir's raillardiopsis, and Muir's raillardella. This plant is related to the of an plants.

Argyroxiphium Virescens
''Argyroxiphium virescens'' was a species of flowering plant in the family Asteraceae that was last seen in 1945. It was found only in the Hawaiian Islands where it was endemic to the eastern part of Maui. Its natural habitats were subtropical or tropical moist montane forests and subtropical or tropical high-altitude shrubland. It is officially declared extinct, but in 1989 plants were discovered that appear to be hybrids between it and the Haleakalā silversword ''Argyroxiphium sandwicense'' subsp. ''macrocephalum'', the east Maui silversword or Haleakala silversword, is a rare plant, part of the family (biology), family Asteraceae. The silversword in general is referred to as ''āhinahina'' in Hawaiian .... This hybrid is known as the Pu'u 'Alaea greensword.

Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do not ...

Kipahulu Valley
Kīpahulu is an unincorporated community in the Hāna district of southeastern Maui, Hawaii. Location and access Kīpahulu is unincorporated and is located south of Hana and east of Kaupo. The only land access to the area is from the north by Hana Highway driving about 45 minutes past Hana or from west by highway 31 (Piilani Highway) which was reopened in 2008 after a nearly two-year closure due to earthquake damage. Piilani Highway is the only major road in Kīpahulu and all populated areas are located along this road. Kīpahulu does not have any electric or water utilities. The only public utility is the telephone. Water is obtained from the streams coming down from Haleakalā and these services are provided to the community by private water systems. History The first written description of Kīpahulu was made by Jean-François de Galaup in 1786 while sailing along the southeast coast of Maui in search of a place to drop anchor: I coasted along its shore at a distanc ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
