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.
Psychotria viridis is a perennial, shrubby flowering plant in the coffee family Rubiaceae. It is a close relative of Psychotria carthagenensis of Ecuador. In the Quechua languages it is called chacruna or chacrona. In Quechua, chaqruy is a verb meaning "to mix".

Psychotria is a genus of flowering plants in the family Rubiaceae. It contains 1,582 species and is therefore one of the largest genera of flowering plants. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests. Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific.
Nepenthes × pyriformis is a natural hybrid involving N. inermis and N. talangensis. It is known only from Mount Talang in Sumatra, to which N. talangensis is endemic. Nepenthes talangensis was only described as a distinct species in 1994. Prior to this it was placed within N. bongso and some of the older literature identifies this hybrid as N. bongso × N. inermis.

The Cuban moist forests is a tropical moist broadleaf forest ecoregion that occupies 21,400 km2 on Cuba and Isla de la Juventud. The ecoregion receives more than 2,000 mm (79 in) of rainfall annually, and does not have a dry season. Soils are usually derived from quartz, limestone, or serpentinites. Cuban moist forests can be differentiated into lowland forests, sub-montane forests, and montane forests.

Psychotridine is an alkaloid found in some species of the genus Psychotria, namely Psychotria colorata, but also Psychotria forsteriana, Psychotria lyciiflora, Psychotria oleoides, and Psychotria beccarioides. Psychotridine has analgesic effects and dose-dependently inhibits dizocilpine binding to cortical membranes in vitro, suggesting that it acts as a non-competitive NMDA receptor antagonist.
