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, ornamental cultivars, and historically some dye plants.
Uncaria is a genus of flowering plants in the family Rubiaceae. It has about 40 species. Their distribution is pantropical, with most species native to tropical Asia, three from Africa and the Mediterranean and two from the neotropics. They are known colloquially as gambier, cat's claw or uña de gato. The latter two names are shared with several other plants. The type species for the genus is Uncaria guianensis.
Psychotria viridis, also known as chacruna, chacrona, or chaqruy in the Quechua languages, is a perennial, shrubby flowering plant in the coffee family Rubiaceae. It is a close relative of Psychotria carthagenensis of Ecuador. It is commonly used as an ingredient of ayahuasca, a decoction with a long history of its entheogenic use and its status as a "plant teacher" among the Indigenous peoples of the Amazon rainforest.
Morinda is a genus of flowering plants in the madder family, Rubiaceae. The generic name is derived from the Latin words morus "mulberry", from the appearance of the fruits, and indica, meaning "of India".
The purple-throated mountaingem is a species of hummingbird in tribe Lampornithini of subfamily Trochilinae. It is found in Costa Rica, Nicaragua, and Panama.
Pentas is a genus of flowering plants in the family Rubiaceae. The genus is found in tropical and southern Africa, the Comoros, Madagascar, and the Arabian Peninsula.
Palicourea is a plant genus in the family Rubiaceae. It contains about 200 species, which range from shrubs to small trees, and is distributed throughout the New World tropics.
Pavetta is a genus of flowering plants in the family Rubiaceae. It comprises about 360 species of trees, evergreen shrubs and sub-shrubs. It is found in woodlands, grasslands and thickets in sub-tropical and tropical Africa and Asia. The plants are cultivated for their simple but variable leaves, usually opposite but also occur in triple whorls. The leaves are often membranous with dark bacterial nodules. Pavetta has small, white, tubular flowers, sometimes salviform or funnel-shaped with 4 spreading petal lobes. The flowers are carried on terminal corymbs or cymes.
Psychotria dura is a species of flowering plant in the family Rubiaceae. It is endemic to Jamaica.
Rothmannia is a genus of flowering plants in the family Rubiaceae. It was described in 1776 and is named for Göran Rothman (1739–1778) by Thunberg – both were pupils of Linnaeus.
Palicourea tomentosa, many synonyms, including Psychotria poeppigiana, is a plant species in the family Rubiaceae. A common name is sore-mouth bush, though it is not very often used.
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.
Kadua is a genus of flowering plants in the family Rubiaceae. It comprises 29 species, all restricted to Polynesia. Twenty-two of these are endemic to the Hawaiian Islands. Some of the species are common at high elevation. Others are single-island endemics or very rare, and a few are probably extinct. Kadua affinis is widely distributed in Hawaii and is polymorphic. The type species for the genus is Kadua acuminata.
Retiniphyllum is a genus of flowering plants in the family Rubiaceae and contains 20 species. It is the only genus in the tribe Retiniphylleae. The representatives are shrubs or small trees that grow in white sand soils in tropical South America. They are mainly distributed in the Guayana Region (Venezuela) but also occur in the Amazon Basin, the eastern Andes and central and eastern Brasil.
Psychotrieae is a tribe of flowering plants in the family Rubiaceae and contains about 2114 species in 17 genera. Its representatives are found in the tropics and subtropics. Several genera are Myrmecophytes
Steenisia is a genus of flowering plants in the family Rubiaceae. The genus is endemic to the island of Borneo.
Palicoureeae is a tribe of flowering plants in the family Rubiaceae and contains about 817 species in 11 genera. Its representatives are found in the tropics and subtropics.
Dr. Charlotte M. Taylor is a botanist and professor specialising in taxonomy and conservation. She works with the large plant family Rubiaceae, particularly found in the American tropics and in the tribes Palicoureeae and Psychotrieae. This plant family is an economically important group, as it includes plant species used to make coffee and quinine. Taylor also conducts work related to the floristics of Rubiaceae and morphological radiations of the group. Taylor has collected plant samples from many countries across the globe, including Chile, Colombia, Costa Rica, Panama, and the United States of America, and has named many new species known to science from these regions. As of 2015, Taylor has authored 278 land plant species' names, the seventh-highest number of such names authored by any female scientist.
Palicourea elata, formerly Psychotria elata, commonly known as girlfriend kiss and labios de puta, is a tropical plant that ranges from Central to South American rain forests in countries such as Mexico, Costa Rica, Ecuador, Panama, and Colombia. Palicourea elata is extremely sensitive and requires specific climates to grow, those climates most like rainforests are best suitable for this plant. It is most notable for its distinctly shaped red bracts and is consequently nicknamed “Hot Lips”. Though the bright red bracts are considered its most flashy feature, they are not the actual flowers of the plant but instead extravagant leaves; the flowers of Palicourea elata lie within the “red lip” leaves. Just like human lips, the hot lips plant comes in a variety of shapes and forms offering a vast array of plants. P. elata is well-studied and has been documented over centuries to provide various health benefits to native communities. Due to these benefits and the overall appearance of the plant, it has been over-harvested and is now endangered.
Samuelssonia is a monotypic genus of flowering plants belonging to the family Acanthaceae. It has only one known species, Samuelssonia verrucosa, a small tree which grows to 5 meters tall which is native to the Massif de la Hotte in Haiti.
