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.
Cordia is a genus of flowering plants in the borage family, Boraginaceae. It contains about 300 species of shrubs and trees, that are found worldwide, mostly in warmer regions. Many of the species are commonly called manjack, while bocote may refer to several Central American species in Spanish.
Celtis is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, widespread in warm temperate regions of the Northern Hemisphere. The genus is part of the extended Cannabis family (Cannabaceae).
Morinda citrifolia is a fruit-bearing tree in the coffee family, Rubiaceae. Its native range extends across Southeast Asia and Australasia, and was spread across the Pacific by Polynesian sailors. The species is now cultivated throughout the tropics and widely naturalized. Among some 100 names for the fruit across different regions are the more common English names of great morinda, Indian mulberry, noni, beach mulberry, vomit fruit, awl tree and cheese fruit.
Lycium is a genus of flowering plants in the nightshade family, Solanaceae. The genus has a disjunct distribution around the globe, with species occurring on most continents in temperate and subtropical regions. South America has the most species, followed by North America and southern Africa. There are several scattered across Europe and Asia, and one is native to Australia. Common English names for plants of this genus include box-thorn and desert-thorn.
Lythrum is a genus of 38 species of flowering plants native to the temperate world. Commonly known as loosestrife, they are among 32 genera of the family Lythraceae.
Sapindus is a genus of about five to twelve species of shrubs and small trees in the lychee family, Sapindaceae, native to warm temperate to tropical regions of the world. The genus includes both deciduous and evergreen species. Members of the genus are commonly known as soapberries or soapnuts because the fruit pulp is used to make soap. The generic name is derived from the Latin words sapo, meaning "soap", and indicus, meaning "of India".
Swietenia is a genus of trees in the chinaberry family, Meliaceae. It occurs natively in the Neotropics, from southern Florida, the Caribbean, Mexico and Central America south to Bolivia. The genus is named for Dutch-Austrian physician Gerard van Swieten (1700–1772). The wood of Swietenia trees is known as mahogany.
Malpighia is a genus of flowering plants in the nance family, Malpighiaceae. It contains about 45 species of shrubs or small trees, all of which are native to the American tropics. The generic name honours Marcello Malpighi, a 17th-century Italian physician and botanist. The species grow to 1–6 m (3.3–19.7 ft) tall, with a dense, often thorny crown. The leaves are evergreen, simple, 0.5–15 cm (0.20–5.91 in) long, with an entire or serrated margin. The flowers are solitary or in umbels of two to several together, each flower 1–2 cm (0.39–0.79 in) diameter, with five white, pink, red, or purple petals. The fruit is a red, orange, or purple drupe, containing two or three hard seeds. M. emarginata is cultivated for its sweet and juicy fruits, which are very rich in vitamin C.
Chamaedorea is a genus of 107 species of palms, native to subtropical and tropical regions of the Americas. They are small palms, growing to 0.3–6 m tall with slender, cane-like stems, growing in the understory in rainforests, and often spreading by means of underground runners, forming clonal colonies. The leaves are pinnate, with one to numerous leaflets. The flowers are produced in inflorescences; they are dioecious, with male and female flowers on separate plants. The fruit is an orange or red drupe 0.5–2 cm diameter. Perhaps the best-known species is Chamaedorea elegans from Mexico and Guatemala. It is popular as a houseplant, particularly in Victorian houses. Another well-known species is Chamaedorea seifrizii, the bamboo palm or reed palm.

Chloroleucon is a genus of flowering plants in the family Fabaceae. It contains 11 species native to the tropical Americas, ranging from Mexico through Central America, the Caribbean, and South America to northern Argentina. Some authorities consider it part of the genus Albizia. Its name is derived from the Greek words χλωρóς (chloros), meaning "green," and λευκός (leukos), meaning "white."
Bunchosia is a genus in the Malpighiaceae, a family of about 75 genera of flowering plants in the order Malpighiales. It contains roughly 75 species of trees and shrubs, which are native to dry woodlands, savannas, and wet forests. Their range extends from Mexico and the Caribbean to southeastern Brazil and adjacent Argentina. Bunchosia is one of three arborescent genera of Malpighiaceae with fleshy, bird-dispersed fruits.
Hamelia is a genus of flowering plants in the coffee family, Rubiaceae. The name honors French botanist Henri-Louis Duhamel du Monceau (1700–1782).
Schaefferia is a genus of flowering shrubs and small trees in the family Celastraceae. The generic name honours German mycologist and clergyman Jacob Christian Schäffer (1718–1790). Members of the genus are found in the Neotropics. The plants are dioecious, with flowers that are unisexual due to abortion. The flowers are usually clustered in the leaf axil, although they are solitary in some species. The calyx of the flowers has four lobes, and the corolla consists of four petals. The ovary consists of two locules; each locule contains a single ovule which develops into a single seed. The fruit is a drupe.
Rondeletia is a genus of flowering plants in the family Rubiaceae. It is endemic to the Neotropics. There are around 160 species.
