Etymology: Camptotheca is a genus of a single species of tree, Camptotheca acuminata, native to southern China, whose name comes from Greek roots meaning "bent" or "curved" and "case" or "box," a reference to the curved, box-like shape of its fruit. The genus was described by the botanists Joseph Decaisne and Henri Decaisne... (see note) Correction to the above: the genus was described in 1877 by the French botanist Joseph Decaisne, who named it from Greek "kampylos" (bent, curved) and "theke" (case, box), the second part referring to the nutlike fruit enclosed in a winged, box-like casing. The tree is known in English as the "happy tree" in Chinese tradition, and its bark and leaves yielded camptothecin, an alkaloid first isolated in 1966 that became the basis for anticancer drugs such as topotecan and irinotecan.

Synonyms: tree of life, Camptotheca acuminata
