Guaraná ( from the Portuguese guaraná [ɡʷaɾɐˈna]; Paullinia cupana, syns. P. crysan, P. sorbilis) is a climbing plant in the family Sapindaceae, native to the Amazon basin and especially common in Brazil. Guaraná has large leaves and clusters of flowers, and is best known for the seeds from its beans, which are about the size of a coffee bean. Guaraná is common in soft drinks in Brazil, and is a major source of caffeine for many South Americans. Products containing guaraná can be effective stimulants: the seeds can be up to about 6% caffeine. For comparison, green coffee beans are about 1–3%

Erythroxylaceae (the coca family) is a family of flowering trees and shrubs consisting of 4 genera and 271 species, native to Africa and South America. The four genera are Aneulophus Benth., Erythroxylum P.Browne, Nectaropetalum Engl., and Pinacopodium Exell & Mendonça.

Myricaceae is a small family of dicotyledonous shrubs and small trees in the order Fagales. Its type genus is Myrica, the sweet gales. There are three genera in the family, although some botanists separate many species from Myrica into a fourth genus Morella. About 55 species are usually accepted in Myrica (with Morella included), one in Canacomyrica, and one in Comptonia. Well-known members of this family include bayberry and sweetfern. Canacomyrica Guillaumin 1940 Comptonia L'Hér. 1789 Myrica L. 1753 (includes Morella Lour. 1790)

The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of woody flowering plants. The actual numbers given in taxonomic sources differ according to taxonomic revision at the time of writing. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs; its species are native to tropical regions of Africa, Asia, Australasia, and the Americas. Because of taxonomic revision, as the family size (in terms of genera and species) differs according to the time period

Pontederiaceae is a family of flowering plants. The APG IV system of 2016 (unchanged from the APG III system of 2009, the APG II system of 2003 and the APG system of 1998) places the family in the order Commelinales, in the commelinid clade, in the monocots. It is a small family of heterostylous aquatic plants, occurring in tropical and subtropical waters. Charles Darwin was interested in the specialized form of heterostyly found in the family, known as tristyly. Not all of the species are heterostylous. The family contains two genera with around 40 known species. It is best known for the

Common names include yellow trumpetbush, yellow bells, yellow elder, ginger Thomas. Tecoma stans is the official flower of the United States Virgin Islands and the floral emblem of The Bahamas.

The Bixaceae are a family of dicotyledonous plants commonly called the achiote family. Under the Cronquist system, the family was traditionally placed in the order Violales. However, newer arrangements move it, with some other families previously in the Violales, into the Malvales. Although small, this family includes trees, herbs, and shrubs. The plants are bisexual, and all species have five sepals. All plants within the Bixaceae produce a red, orange, or yellow latex.

Byrsonima crassifolia is a species of flowering plant in the family Malpighiaceae, native to tropical America. Common names used in English include nance, maricao cimun, craboo, and golden spoon. In Jamaica it is called hogberry. The plant is valued for its small (between one, and one and a quarter centimeter in diameter) round, sweet yellow fruit, which is strongly scented. The fruits have a very pungent and distinct flavor and smell. When jarred, their texture resembles that of a green or kalamata olive.

Bactris gasipaes is a species of palm native to the tropical forests of Central and South America. It is well spread in these regions, where it is often cultivated by smallholders in agroforestry systems or more rarely, in monoculture. Common names include peach palm in English, among others used in South American countries. It is a long-lived perennial plant that is productive for 50 to 75 years on average. Its population has an important genetic diversity, leading to numerous fruits, colors, and qualities. The fruits are edible and nutritious but need to be cooked for 30 minutes to five

It is an important multi-purpose legume tree, with a native range from Mexico to Colombia, but now widely introduced to other tropical zones.

Pterocarya, often called wingnuts in English, are trees in the walnut family Juglandaceae. They are native to Asia and parts of Europe. The botanic name is from Ancient Greek πτερόν (pteron) "wing" + κάρυον (karyon) "nut". The genus is of particular scientific interest as a classic relict lineage, with a modern distribution disjunct between East Asia and the Caucasus–West Asian region, while its fossil record shows it was once widespread across much of the Northern Hemisphere. Many fossils are known from the New World and the genus survived in the New world till the Pliocene. Most species of

It has a mustard-like odor when crushed.

Attalea is a large genus of palms native to Mexico, the Caribbean, Central and South America. This pinnately-leaved, non-spiny genus includes both small palms without an aboveground stem and large trees. The genus has a complicated taxonomic history and has often been divided into four or five genera based on differences in male flowers. Since the genera can only be distinguished on the basis of their male flowers, the existence of intermediate flower types and the existence of hybrids between different genera has been used as an argument for keeping them all in the same genus. This has been

Chusquea is a genus of evergreen bamboos in the grass family. Most of them are native to mountain habitats in Latin America, from Mexico to southern Chile and Argentina. They are sometimes referred to as South American mountain bamboos. Unlike most other grasses, the stems of these species are solid, not hollow. Some animals are, to various extents, associated with stands of Chusquea, for example the Inca wren, monito del monte, and the plushcap.

Chloris gayana is a species of grass known by the common name Rhodes grass. It is native to Africa but it can be found throughout the tropical and subtropical world as a naturalized species. It can grow in many types of habitat. It is also cultivated in some areas as a palatable graze for animals and a groundcover to reduce erosion and quickly revegetate denuded soil. It is tolerant of moderately saline and alkaline soils and irrigation.

Altensteinia is a genus of orchids. It is found in the Andean region of South America. At present (May 2014), eight species are accepted.

Alnus acuminata is a species of deciduous tree in the Betulaceae family. It is found in montane forests from central Mexico to Argentina.

Lonchocarpus is a plant genus in the legume family (Fabaceae). It includes 166 species native to the tropical Americas, tropical Africa, and Madasgascar. The species are called lancepods due to their fruit resembling an ornate lance tip or a few beads on a string. Cubé resin is produced from the roots of L. urucu and namely ''L. utilis (cubé). It contains enough of the toxic rotenoids rotenone and deguelin to be used as an insecticide and piscicide. As these are naturally occurring compounds, they were formerly used in organic farming. Since it is highly unselective and kills useful, as well

Lemna minuta is a species of duckweed known by the common name least duckweed. It is the smallest Lemna species. It is native to parts of the Americas, and naturalized in others; the exact native range is not known. It is found on other continents as a non-native introduction as well. The plant's distribution is ever-expanding; it has been spreading in Europe and it was described from Poland for the first time in 2007. In many areas it is a noxious weed, such as in Belgium. This tiny plant varies in shape depending on growth conditions. In the shade it is a single green translucent oval body

Beschorneria is a genus of succulent plants belonging to the family Asparagaceae, subfamily Agavoideae, native to semi-arid areas of Mexico and Central America.

Salvia microphylla, synonyms including Salvia grahamii, Salvia lemmonii and Salvia neurepia, the baby sage, Graham's sage, or blackcurrant sage, is an evergreen shrub found in the wild in southeastern Arizona and the mountains of eastern, western, and southern Mexico. It is a very complex species which easily hybridizes, resulting in numerous hybrids and cultivars brought into horticulture since the 1990s. The specific epithet microphylla, from the Greek, means "small leaved". In Mexico it is called mirto de montes, or "myrtle of the mountains".

Restrepia, abbreviated Rstp in horticultural trade, is a small genus of 50 species in the orchid family (Orchidaceae), closely related to Pleurothallis. Named in honor of Don Jose Restrepo, it tends to be more showy than most other Pleurothallids. They are found primarily at higher altitudes in the cool, damp montane forests of the Andes and Venezuela, with some into Central America up to southern Mexico.

Cercocarpus, commonly known as mountain mahogany, is a small genus of at least nine species of nitrogen-fixing flowering plants in the rose family, Rosaceae. They are native to the western United States and northern Mexico, where they grow in chaparral and semidesert habitats and climates, often at high altitudes. Several are found in the California chaparral and woodlands ecoregion. The classification of Cercocarpus within the Rosaceae has been unclear. The genus has been placed in the subfamily Rosoideae, but is now placed in subfamily Dryadoideae. Members of the genus are deciduous shrubs

Passiflora vitifolia, the perfumed passionflower, is a species of Passiflora native to southern Central America and northwestern South America.

Nothoscordum is a genus of New World plants in the onion tribe within the Amaryllis family. It is probably paraphyletic. The genus is native to North, Central and South America, though a few species have become naturalized in various parts of the Old World. Nothoscordum is a conserved name. It's synonymous with Pseudoscordum, which was described in 1837 by William Herbert as a reclassification of some Allium species. The term Nothoscordum comes from the fourth volume of Carl Sigismund Kunth's work Enum. Pl., published six years later in 1843.
