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 species include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, some dye plants, and ornamental cultivars.
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.
Gentianales is an order of flowering plants, included within the asterid clade of eudicots. It comprises more than 16,000 species in about 1,138 genera in 5 families. More than 80% of the species in this order belong to the family Rubiaceae.

Ixora is a genus of flowering plants in the family Rubiaceae. It is the only genus in the tribe Ixoreae. It consists of tropical evergreen trees and shrubs and holds around 562 species. Though native to the tropical and subtropical areas throughout the world, its centre of diversity is in Tropical Asia. Ixora also grows commonly in subtropical climates in the United States, such as Florida where it is commonly known as West Indian jasmine. Other common names include viruchi, rangan, kheme, ponna, chann tanea, techi, pan, siantan, jarum-jarum/jejarum, jungle flame, jungle geranium, and cruz de Malta, among others. The plants possess leathery leaves, ranging from 3 to 6 inches in length, and produce large clusters of tiny flowers in the summer. Members of Ixora prefer acidic soil, and are suitable choices for bonsai. It is also a popular choice for hedges in parts of South East Asia. In tropical climates they flower year round and are commonly used in Hindu worship, as well as in ayurveda and Indian folk medicine.
