"), which accounts for about 20–40%. '' C. arabica'' is preferred for its sweeter taste, while ''C. canephora'' has a higher caffeine content. ''C. arabica'' has its origins in the highlands of Ethiopia and the Boma Plateau of Sudan, and was the result of a hybrid between ''C. canephora'' and ''C. eugenioides''. The trees produce edible red or purple fruits, which are described either as epigynous berries or as

simultaneously attracts pollinators, specifically honeybees, by creating an olfactory memory that signals bees to return to the plant's flowers. Not all ''Coffea'' species contain caffeine, and the earliest species had little or no caffeine content.

Caffeine has also evolved independently in the more distantly related genera ''

. In 2011, ''Coffea'' absorbed the twenty species of the former genus ''Psilanthus'' due to the morphological and genetic similarities between the two genera. Historically, the two have been considered distinct genera due to differences in the length of the corolla tube and the anther arrangement: ''Coffea'' with a short corolla tube and exserted style and anthers; ''Psilanthus'' with a long corolla tube and included anthers. However, these characteristics were not present in all species of either respective genus, making the two genera overwhelmingly similar in both morphology and genetic sequence. This transfer expanded ''Coffea'' from 104 species to 124, and extended its native distribution to tropical Asia and Australasia. In 2014, the coffee

s identified. This revealed that coffee plants make caffeine using a different set of genes from those found in

, cacao and other such plants. In 2017, a robust and almost fully resolved phylogeny of the entire genus was published. In addition to resolving the relationships of ''Coffea'' species, this study's results suggest Africa or Asia as the likely ancestral origin of Coffea and point to several independent radiations across Africa, Asia, and the Western Indian Ocean Islands. In 2020 a technique of DNA fingerprinting, or genetic authentication of plant material was proven effective for coffee. For the study, scientists used DNA extraction and SSR marker analysis. This technique or ones similar may allow for several improvements to coffee production such as improved information for farmers as to the susceptibility of their coffee plants to pests and disease, a professionalized coffee seed system, and transparency and traceability for buyers of green, un-roasted coffee.
