Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...

Hibiscus
''Hibiscus'' is a genus of flowering plants in the mallow family, Malvaceae. The genus is quite large, comprising several hundred species that are native to warm temperate, subtropical and tropical regions throughout the world. Member species are renowned for their large, showy flowers and those species are commonly known simply as "hibiscus", or less widely known as rose mallow. Other names include hardy hibiscus, rose of sharon, and tropical hibiscus. The genus includes both annual and perennial herbaceous plants, as well as woody shrubs and small trees. The generic name is derived from the Greek name ἰβίσκος (''ibískos'') which Pedanius Dioscorides gave to ''Althaea officinalis'' ( 40–90 AD). Several species are widely cultivated as ornamental plants, notably ''Hibiscus syriacus'' and ''Hibiscus rosa-sinensis''. A tea made from hibiscus flowers is known by many names around the world and is served both hot and cold. The beverage is known for its red colour, t ...

Hawaiian Hibiscus
Hawaiian hibiscus are seven species of hibiscus native to Hawaii. The yellow hibiscus is Hawaii's state flower. Most commonly grown as ornamental plants in the Hawaiian Islands are the non-native Chinese hibiscus (''Hibiscus rosa-sinensis'') and its numerous hybrids, though the native ''Hibiscus arnottianus'' is occasionally planted. The native plants in the genus ''Hibiscus'' in Hawaii are thought to have derived from four independent colonization events for the five endemic species (four closely related species plus the yellow-flowered species) and one each for the two indigenous species. Native species The native hibiscus found in Hawaii are: *'' Hibiscus arnottianus'' A.Gray – ''kokio keokeo'' ("''kokio'' that is white like the shine of silver") is an endemic species of hibiscus with white flowers. Three subspecies are recognized: ''H. arnottianus'' ssp. ''arnottianus'' found in the Waianae Range of western Oahu; ''H. a.'' ssp. ''immaculatus'' which is very rare (l ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Otto Degener
Otto Degener (May 13, 1899 – January 16, 1988) was a botanist and conservationist who specialized in identifying plants of the Hawaiian Islands. Biography Degener was born May 13, 1899 in East Orange, New Jersey. Degener graduated from the Massachusetts Agricultural College (now University of Massachusetts Amherst). Intending to spend a year as a tourist, he arrived in Hawaii but decided to stay. He received his MA from the University of Hawaii in 1922 and his PhD from Columbia University. He taught Botany at the University of Hawaii from 1925 to 1927, and was the first naturalist for what are now Hawaii Volcanoes National Park and Haleakala National Park.

Althaea Officinalis
''Althaea officinalis'', the marsh mallow or marshmallow, is a species of flowering plant indigenous to Europe, Western Asia and North Africa, which is used in herbalism and as an ornamental plant. A confection made from the root since ancient Egyptian times evolved into today's marshmallow treat, but most modern marshmallow treats no longer contain any marsh-mallow root. Description This herbaceous perennial has stems which die down in the autumn, They typically grow , but can reach and put out only a few lateral branches. The leaves are shortly petioled, roundish, ovate-cordate, long, and about broad, entire or three to five lobed, irregularly toothed at the margin, and thick. They are soft and velvety on both sides, due to a dense covering of stellate hairs. The lilac-pink flowers are shaped like those of the common mallow, but are smaller and of a pale colour, and are either axillary, or in panicles, more often the latter. The stamens are united into a tube, the anthe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedanius Dioscorides
Pedanius Dioscorides ( grc-gre, Πεδάνιος Διοσκουρίδης, ; 40–90 AD), “the father of pharmacognosy”, was a Greek physician, pharmacologist, botanist, and author of ''De materia medica'' (, On Medical Material) —a 5-volume Greek encyclopedia about herbal medicine and related medicinal substances (a pharmacopeia), that was widely read for more than 1,500 years. For almost two millennia Dioscorides was regarded as the most prominent writer on plants and plant drugs. Life A native of Anazarbus, Cilicia, Asia Minor, Dioscorides likely studied medicine nearby at the school in Tarsus, Mersin, Tarsus, which had a pharmacological emphasis, and he dedicated his medical books to Laecanius Arius, a medical practitioner there. Though he writes he lived a "soldier's life" or "soldier-like life", his pharmacopeia refers almost solely to plants found in the Greek-speaking eastern Mediterranean, making it likely that he served in campaigns, or travelled in a civilian ca ...
