Rubiaceae in the context of "Liana"

Poaceae (/poʊˈeɪsi.iː, -ˌaɪ/ poh-AY-see-e(y)e), also called Gramineae (/ɡrəˈmɪni.iː, -ˌaɪ/ grə-MIN-ee-e(y)e), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as true grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. Poaceae is the most well-known family within the informal group known as grass.

With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae.

Coffea is a genus of flowering plants in the family Rubiaceae. Coffea species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste.

The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa. The coffee trade relies heavily on two of the over 120 species, Coffea arabica (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and Coffea canephora (known as "Robusta"), which accounts for about 20–40%.

Rubia is the type genus of the Rubiaceae family of flowering plants, which also contains Coffea (coffee). It contains around 80 species of perennial scrambling or climbing herbs and subshrubs native to the Old World.

The genus and its best-known species are commonly known as madder, e.g. Rubia tinctorum (common madder), Rubia peregrina (wild madder), and Rubia cordifolia (Indian madder).

Galium is a large genus of annual and perennial herbaceous plants in the family Rubiaceae, occurring in the temperate zones of both the Northern and Southern Hemispheres. Some species are informally known as bedstraw.

Over 600 species of Galium are described, with estimates of 629 to 650 as of 2013. The field madder, Sherardia arvensis, is a close relative and may be confused with a tiny bedstraw. Asperula is also a closely related genus; some species of Galium (such as woodruff, G. odoratum) are occasionally placed therein.

Coffea canephora (especially C. canephora var. robusta, so predominantly cultivated that it is often simply termed Coffea robusta, or commonly robusta coffee) is a species of coffee plant that has its origins in central and western sub-Saharan Africa. It is a species of flowering plant in the family Rubiaceae. Though widely known as Coffea robusta, the plant is scientifically identified as Coffea canephora, which has two main varieties, robusta and nganda.

Coffea robusta represents between 40% and 45% of global coffee production, with Coffea arabica constituting most of the remainder. There are several differences between the composition of coffee beans from C. arabica and C. robusta. Beans from C. robusta tend to have lower acidity, more bitterness, and a more woody and less fruity flavor compared to C. arabica beans. Most of it is used for instant coffee.
