Coffea arabica
species of plant
Coffea arabica (), also known as the Arabica coffee, is a species of flowering plant in the coffee and madder family Rubiaceae. It is believed to be the first species of coffee to have been cultivated and is the dominant cultivar, representing about 60% of global production. Coffee produced from the less acidic, more bitter, and more highly caffeinated robusta bean (C. canephora) makes up most of the remaining coffee production. The natural populations of Coffea arabica are restricted to the forests of South Ethiopia, South Sudan, and Yemen.
Description
Wild plants grow between 9 and 12 m (30 and 39 ft) tall, and have an open branching system; the leaves are opposite, simple elliptic-ovate to oblong, 6–12 cm (2.5–4.5 in) long and 4–8 cm (1.5–3 in) broad, glossy dark green, with prominent veins and wavy margins.
The flowers are white, 10–15 mm in diameter, and grow in axillary clusters of 2 to 9. The fruit is a drupe (commonly called a "cherry") 10–15 mm in diameter, maturing bright red to purple and typically containing two seeds each which become coffee beans.
Taxonomy
The botanical name Coffea arabica was formally published by Carl Linnaeus in his Species plantarum in 1753. The species had been described and depicted before, as Linnaeus was able to refer to Antoine de Jussieu, who named it Jasminum arabicum, published in 1715, after studying a specimen sent to him from the Botanic Garden of Amsterdam, Gaspard Bauhin's Pinax of 1623 under 'Evonymus IV' and Prospero Alpini's De plantis Aegypti liber, published in 1592.
Coffea arabica is one of the polyploid species of the genus Coffea, as it carries four copies of the eleven chromosomes (44 total) instead of the 2 copies of diploid species.
Begin with the source’s own compact description: “Coffea arabica” is species of plant. The dossier treats that line as a proposition to test through Coffea, arabica and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 26, 2026. The linked authority identifier is Q47685. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1753, 1715, 1623 and 1592.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
