The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, some dye plants, and ornamental cultivars.
Gardenia is a genus of flowering plants in the coffee family, Rubiaceae, native to the tropical and subtropical regions of Africa, Asia, Madagascar and Pacific Islands, and Australia.
Alberta is a monotypic genus of flowering plants in the family Rubiaceae. Most species have been transferred to the genus Razafimandimbisonia, except for the type species Alberta magna. It is native to KwaZulu-Natal, South Africa and is commonly known as Natal flame bush.
Gardenia anapetes is a species of plant in the family Rubiaceae. It is endemic to the Fiji island of Vanua Levu. The native gardenias of Fiji possess a diverse array of natural products. Methoxylated and oxygenated flavonols and triterpenes accumulate on the vegetative- and floral-buds as droplets of secreted resin. Phytochemical studies of these bud exudates have been published, including a population-level study of two other rare, sympatric species on Vanua Levu Island, G. candida and G. grievei.
Gardenia brighamii, commonly known as nānū, naʻu, or forest gardenia, is a species of flowering plant in the coffee family, Rubiaceae, that is endemic to Hawaii.
Gardenia candida is a species of asterid flowering plant in the family Rubiaceae. This species is endemic to Fiji with populations known from dry tropical forest thickets on the Island of Vanua Levu, and from tropical forests of Viti Levu Island. Native gardenias of the Fiji Islands and elsewhere in the paleotropics possess a diverse array of natural products. Methoxylated and oxygenated flavonols and triterpenes accumulate on the vegetative- and floral-buds as yellow to brown droplets of secreted resin. Focused phytochemical studies of these bud exudates have been published, including a population-level study of another rare, sympatric species, G. grievei.
Gardenia grievei is a species of asterid flowering plant in the family Rubiaceae. This species, among others, is endemic to Fiji with populations known from Vanua Levu and Viti Levu islands. Native gardenias of the Fiji Islands and elsewhere in the paleotropics possess a diverse array of natural products including methoxylated and oxygenated flavonols and triterpenes. These secondary plant substances accumulate on the vegetative- and floral-buds as yellow to brown droplets of secreted resin. Focused phytochemical studies of these bud exudates have been published, including a population-level study of a sympatric species, G. candida
Gardenia gummifera is a species of plant in the family Rubiaceae. It is endemic to India.
Gardenia hillii is a species of plant in the family Rubiaceae. It is endemic to Fiji.
Gardenia hutchinsoniana is a species of plant in the family Rubiaceae. It is endemic to Fiji.
Gardenia mannii, the nānū, Oahu gardenia or Mann's gardenia, is a species of flowering tree in the coffee family, Rubiaceae, that is endemic to the island of Oʻahu in Hawaiʻi. It inhabits coastal mesic, mixed mesic, and wet forests at elevations of 100–730 m (330–2,400 ft) in the Koʻolau and Waiʻanae Ranges. It is threatened by habitat loss.
Gardenia remyi, the nānū or Remy's gardenia, is a species of flowering tree in the madder family, Rubiaceae.
Gardenia storckii is a species of plant in the family Rubiaceae. It is endemic to Fiji. The native gardenias of Fiji possess a diverse array of natural products. Methoxylated and oxygenated flavonols and triterpenes accumulate on the vegetative- and floral-buds as droplets of secreted resin. Phytochemical studies of these bud exudates have been published, including a population-level study of two other rare, sympatric species on Vanua Levu Island in the Fiji archipelago, G. candida and G. grievei.
Gardenia transvenulosa is a species of plant in the family Rubiaceae. It is found in Kenya and Tanzania.
Guettarda speciosa, with common names sea randa, or zebra wood, is a species of shrub in the family Rubiaceae found in coastal habitats in tropical areas around the Pacific Ocean, including the coastline of central and northern Queensland and Northern Territory in Australia, and Pacific Islands, including Micronesia, French Polynesia and Fiji, Malaysia and Indonesia, Maldives and the east coast of Africa. It reaches 6 m in height, has fragrant white flowers, and large green prominently-veined leaves. It grows in sand above the high tide mark.
Atractocarpus is a genus of flowering plants in the family Rubiaceae. Its members are commonly known as native gardenias in Australia. The genus name is derived from the Ancient Greek terms atractos "spindle", and karpos "fruit", from the spindle-shaped fruit of the type species.
Gardenieae is a tribe of flowering plants in the family Rubiaceae and contains about 586 species in 53 genera.
Gardenia actinocarpa is a rare and endangered plant in the madder family Rubiaceae that grows in a very restricted area within the Wet Tropics rainforest of north-east Queensland.
Atractocarpus hirtus, commonly known as the hairy gardenia or native loquat, is a plant in the madder family Rubiaceae, a large family of some 6,500 species with a cosmopolitan distribution. This species is endemic to north-east Queensland, Australia.
Dutailliopsis gordonii is a species of flowering plants in the monotypic genus of Dutailliopsis and belongs to the family Rutaceae.
