Coffeae

Coffeae is a tribe within the family Rubiaceae, which is a large group of flowering plants known for their diverse range of species. The tribe Coffeae is particularly notable for its inclusion of the coffee plant, Coffea, which is the source of the popular beverage coffee. The tribe is characterized by its small, often fragrant flowers and the presence of a nectary at the base of the corolla. This nectary is a specialized structure that produces nectar, which is essential for attracting pollinators.

The Coffeae tribe is distributed across various regions, including tropical and subtropical areas. It is estimated to contain around 100 species, with Coffea being the most well-known genus within the tribe. The coffee plant, Coffea arabica and Coffea robusta, are the primary sources of commercial coffee production. These species are valued for their unique flavor profiles and are cultivated in many countries around the world.

In addition to the coffee plant, the Coffeae tribe includes other genera such as Faramea, Geophila, and Ixora. These genera contribute to the biodiversity of the Rubiaceae family and are studied for their ecological and botanical significance. The tribe's members often exhibit a range of ecological adaptations, including the ability to grow in diverse environments and the production of various secondary metabolites.

The Coffeae tribe plays a significant role in both ecological and economic contexts. From an ecological perspective, it contributes to the biodiversity of its habitat and supports various pollinators. Economically, the coffee plant is a major source of income for many regions, particularly in countries like Brazil, Vietnam, and Colombia. The tribe's members are also studied for their potential in pharmaceutical and agricultural research, highlighting their importance in both natural and applied sciences.
