Orange Striped Horned

Citrus aurantium var. corniculata - Horned Bitter Orange

The Horned Bitter Orange fascinates with its extraordinary deformity: its fruits develop horn-shaped excrescences, bumps, and furrows that vary infinitely from one specimen to another.

No tree produces two identical fruits, and some remain simply bumpy while others display true protuberances. Even more astonishing: Poiteau reported that the seeds of this bitter orange tree could contain up to five complete embryos nested within each other, an unexplained botanical curiosity in its time.

The Horned Bitter Orange tree shares the elegant habit and floral beauty of its cousin, the Crowned Bitter Orange tree.

Its voluminous and sweet-smelling flowers are sought after in sacristies. The horns that give the fruit its name are merely dilated peel: they contain neither locules nor seeds, but their presence sometimes deforms the inner segments.

Duhamel had hypothesized a correspondence between the number of supernumerary petals and that of the excrescences, but Poiteau refuted this theory: fruit and petals do not have a sufficient organic relationship for such a link to exist. The infinite variability of forms makes each horned bitter orange a unique botanical object.

This plate is taken from Pierre-Antoine Poiteau and Pierre Jean François Turpin's Traité des Arbres Fruitiers, a botanical encyclopedia published between 1807 and 1835, a major reference in 19th-century naturalist illustration.

It combines the rigor of scientific drawing with a rare artistic sensitivity, characteristic of the great plates from the golden age of illustrated botany.
