Ophiorrhiza is a genus of flowering plants in the coffee family (Rubiaceae). It contains 378 species native to the Indian subcontinent, Indochina, China, Taiwan, Japan, Malesia, Papuasia, Queensland, and the South Pacific. [1] Species of the genus contain camptothecin, an alkaloid used to make chemotherapeutic agents. [2] [3] Many Ophiorrhiza species are endemic to certain areas of the Western Ghats.

<i>Arabidopsis</i> Genus of flowering plants

Arabidopsis (rockcress) is a genus in the family Brassicaceae. They are small flowering plants related to cabbage and mustard. This genus is of great interest since it contains thale cress, one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced. Changes in thale cress are easily observed, making it a very useful model.

<span class="mw-page-title-main">Rubiaceae</span> Family of flowering plants including coffee, madder and bedstraw

Rubiaceae is 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 14,100 species in about 580 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.

<span class="mw-page-title-main">Annonaceae</span> Family of flowering plants

The Annonaceae are a family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably Annona, Anonidium, Asimina, Rollinia, and Uvaria. Its type genus is Annona. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the remaining are Indomalayan.

<i>Catharanthus</i> Genus of flowering plants

Catharanthus is a genus of flowering plants in the family Apocynaceae. Like the genus Vinca, they are known commonly as periwinkles. There are eight known species. Seven are endemic to Madagascar, though one, C. roseus, is widely naturalized around the world. The eighth species, C. pusillus, is native to India and Sri Lanka. The name Catharanthus comes from the Greek for "pure flower".

Aglycyderini is a tribe of belids, primitive weevils of the family Belidae. Like in other belids, their antennae are straight, not elbowed as in the true weevils (Curculionidae). They occur only on the Pacific Islands and in the Macaronesian region.

The Synergistota is a phylum of anaerobic bacteria that show Gram-negative staining and have rod/vibrioid cell shape. Although Synergistota have a diderm cell envelope, the genes for various proteins involved in lipopolysaccharides biosynthesis have not yet been detected in Synergistota, indicating that they may have an atypical outer cell envelope. The Synergistota inhabit a majority of anaerobic environments including animal gastrointestinal tracts, soil, oil wells, and wastewater treatment plants and they are also present in sites of human diseases such as cysts, abscesses, and areas of periodontal disease. Due to their presence at illness related sites, the Synergistota are suggested to be opportunistic pathogens but they can also be found in healthy individuals in the microbiome of the umbilicus and in normal vaginal flora. Species within this phylum have also been implicated in periodontal disease, gastrointestinal infections and soft tissue infections. Other species from this phylum have been identified as significant contributors in the degradation of sludge for production of biogas in anaerobic digesters and are potential candidates for use in renewable energy production through their production of hydrogen gas. All of the known Synergistota species and genera are presently part of a single class (Synergistia), order (Synergistiales), and family (Synergistaceae).

<i>Kadua</i> Genus of flowering plants

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 Solanaceae, or the nightshades, is a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell, and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.

<i>Chonemorpha fragrans</i> Species of flowering plant in the family Apocynaceae

Chonemorpha fragrans, the frangipani vine or climbing frangipani, is a plant species in the genus Chonemorpha. It is a vigorous, generally evergreen, climbing shrub producing stems 30 m (98 ft) or more long that can climb to the tops of the tallest trees in the forests of Southeast Asia. It has scented, white flowers and large shiny leaves. It is native to China, India, Indonesia, Malaysia, Myanmar, Sri Lanka and Thailand. It is very commonly used in Ayurveda and it is also cultivated mostly worldwide in frost-free places.
