Hibiscadelphus
''Hibiscadelphus'' is a genus of flowering plants that are endemic to Hawaii, Hawaii. It is known by the Native Hawaiians as ''hau kuahiwi'' which means "mountain Hibiscus". The Latin name ''Hibiscadelphus'' means "brother of ''Hibiscus''". It is distinctive for its peculiar flowers, which do not fully open. ''Hibiscadelphus'' is in the family Malvaceae, subfamily Malvoideae. Several of the species in this small genus are presumed extinct, as a result of coextinction with their primary pollinators, the Hawaiian honeycreepers. Description ''Hibiscadelphus'' was first described by Austrian-American botanist Joseph Rock in 1911 on the basis of the species ''Hibiscadelphus giffardianus''. Species in this genus are large shrubs or small trees, up to tall, with nearly circular leaves. The genus is characterized by flowers that never open to the flat form of ''Hibiscus'', but remain folded together in a tubular form. This is presumed to be an adaptation to pollination by Hawaiian ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hibiscadelphus Distans
''Hibiscadelphus distans'' (Kauai hau kuahiwi) is an extremely rare species of flowering plant in the mallow family, Malvaceae, that is endemic to the island of Kauai in Hawaii.

Hibiscadelphus Stellatus
''Hibiscadelphus stellatus'' is a species of flowering plant in the mallow family, Malvaceae. It is called stellar hau kuahiwi in the United States Department of Agriculture PLANTS database. It is endemic to West Maui, Hawaii. It was first formally described in 2014.

Bracts are usually different from foliage leaves in size, color, shape or texture. They also loo ...s, as well as its "beautiful and stellar (outstanding) flowers".

Malvoideae
Malvoideae is a botanical name at the rank of subfamily, which includes in the minimum the genus ''Malva''. It was first used by Burnett in 1835, but was not much used until recently, where, within the framework of the APG System, which unites the families Malvaceae, Bombacaceae, Sterculiaceae and Tiliaceae of the Cronquist system, the aggregate family Malvaceae is divided into 9 subfamilies, including Malvoideae. The Malvoideae of Kubitzki system, Kubitzki and Bayer includes 4 tribes: * Malveae (''Abutilon, Alcea, Malva, Sidalcea'' etc.) * Gossypieae (''Gossypium'', the cottons etc.) * Hibisceae (''Hibiscus'' etc.) * Kydieae * - and two unplaced genera:- ** ''Jumelleanthus'' ** ''Howittia'' The genus ''Alyogyne'' was once included in the genus ''Hibiscus'' but is not included there anymore. It is not placed in the Hibisceae either and some resources, such as the Germplasm Resources Information Network, GRIN include it in the Gossypieae. The GRIN also excludes ''Thepparatia'' from ...

Coextinction
Coextinction and cothreatened refer to the phenomenon of the loss or decline of a host species resulting in the loss or endangerment of another species that depends on it, potentially leading to cascading effects across trophic levels. The term was originated by the authors Stork and Lyal (1993) and was originally used to explain the extinction of parasitic insects following the loss of their specific hosts. The term is now used to describe the loss of any interacting species, including competition with their counterpart, and specialist herbivores with their food source. Coextinction is especially common when a keystone species goes extinct. Causes The most frequently cited example is that of the extinct passenger pigeon and its parasitic bird lice '' Columbicola extinctus'' and ''Campanulotes defectus''. Recently, ''C. extinctus'' was rediscovered on the band-tailed pigeon, and ''C. defectus'' was found to be a likely case of misidentification of the existing '' Campanulotes ...

North Kona
Kona is a ''moku'' or district on the Big Island of Hawaii in the State of Hawaii, known for its Kona coffee and the Ironman World Championship Triathlon. In the administration of Hawaii County, the ''moku'' of Kona is divided into North Kona District (''Kona Akau'') and South Kona District (''Kona Hema''). "Kona" sometimes refers to its largest town, Kailua-Kona. Other towns in Kona include Kealakekua, Keauhou, Holualoa, Hōnaunau and Honalo. Description In the Hawaiian language, ''kona'' means leeward or dry side of the island, as opposed to ''ko‘olau'' which means windward or the wet side of the island. In the times of Ancient Hawaiʻi, ''Kona'' was the name of the leeward district on each major island. In Hawai‘i, the Pacific anticyclone provides moist prevailing northeasterly winds to the Hawaiian islands, resulting in rain when the winds contact the windward landmass of the islands – the winds subsequently lose their moisture and travel on to the leeward (or ...
